How to make a 24’ runabout out of two 20’ boats

Words © by Chris (Seabuddy) Brown

This classic 24’ inboard/outboard boat is waiting for a customer to specify a vee-drive shaft drive in the traditional inboard manner. All the other features and desirable traits of a runabout are in place. She runs, rides, and turns like a gem.

The Cherubini 24’ was created by the company using their 20’ boat model. As a family, they have been building boats back to 1937. The current boat company goes back to 1975. Over this time they have worked their magic in many ways. This is an article about one of their magic moments in a long history of inspired boat building.

It looks like they bought the molds and rights to a water jet powered 20’ runabout from an out of business boat builder. They changed that hull to be a stylish, real sweet running I/O boat. Yes, other power is offered from the factory, but all the units seem to use inboard/outboard power.

I now want to drill down to how they created a 24’ boat. They took TWO examples of their sweet running 20’, cut them down the middle (but on an slant) added 4’ in the center, put this all into one boat and blended all of this using their boat building expertise into a 24’ boat. No flat spots, no seams, nothing that does not pass close inspection. I could not do this. Kudos to them.

BTW, they went from a V-6 Mercury Marine GM block powered 20’ boat to a 496 cu. in. displacment, again Chevy GM block, Mercury Marine engine in the 24’. Both boats run much faster than most true classic boats. The 24’ can top 65 MPH with its big block engine.

Has this type of thing been done before? Most say, yes. There are plans and drawings for the classic Donzi 16 and the Donzi 22 models. No drawing or plans for the Donzi 18 boat. The story goes that the 16’s bow and aft sections where cut and two feet were added in the middle to make the Donzi 18.

Boat Trim Tabs: One System’s Ideas

IBEX is an annual marine trade event that provides an opportunity to interact with boat builders and other marine professionals worldwide, to collect immediate feedback, and to form lasting relationships in just three days. IBEX offers marine professionals a single platform to meet the North American marine industry face-to-face about the products that boating and boaters use.

Presented here is one idea that struck Seabuddy as newsworthy for a LinkedIn Pulse listing.

These folks make a system that retro-fit their marine trim tabs to other systems.

Manufacturer’s comment…  “Are you frustrated with your messy hydraulic pump unit? One of the biggest concerns with the hydraulic pump units are their possibility of messy leakage of harmful toxins to the environment. Not to mention the oily mess. But another big concern is the well known slow response of hydraulic units”.

This is a good, short video to watch.

More from Lenco…  “The Conversion & Performance Upgrade Kit includes everything necessary to upgrade your current boat without any drilling or filling of holes. You simply discard the hydraulic pump unit and the two Bennett cylinders. Lenco’s new upper mounting brackets fit the existing Bennett mounting holes on the transom. Install the two Lenco electric actuators on your existing Bennett trim blades using the existing lower actuator brackets. Connect our actuator wiring to the existing harness. Jumper wires are included for attaching to current Bennett rocker switch. Complete your trim tab system upgrade with a waterproof Lenco tactile switch or our Auto Glide Boat Leveling System.”

Chris Craft’s newest engine 2015

 

 

stern drive gas engine chris craft 2015

Chris Craft newest engine

This one comes from Chevy/ GM like many of the classic era engines. It is a powerful engine in a Chris Craft. It acts like a big block but is within the small block family tree.

 

What is different with this engine? The block is aluminum, not cast iron, so it is a light weight package and comes with closed cooling, so the engine internals never touches the water that you boat in. The valve train features VVT or continuously variable valve timing (VVT). Chevy says “Athletes understand that proper breathing is critical to maintaining peak performance under all conditions, and so do Chevrolet powertrain engineers. Getting air in and exhaust gases out of the combustion chamber under all speeds [makes more power]. Chevrolet’s VVT system uses electro-hydraulic actuators between the drive sprocket and camshaft to twist the cam relative to the crankshaft position. Adjusting the cam phasing in this manner allows the valves that are actuated by that camshaft to be opened and closed earlier or later.”

 

Hot Rod magazine says “The beauty of VVT is that an improvement in high-rpm power doesn’t sacrifice bottom-end torque.”

 

Volvo marinized this Chevy V8-380 (and its sister 430 HP version) for Chris Craft. Volvo says “it is the next generation of gasoline engine performance for powerboats. Modern technology and advanced design deliver improved acceleration, impressive mid-range response, reduced fuel consumption, reduced emissions and quiet, smooth operation. All in a lighter and more durable package. This next generation engine is a perfect match for the Duoprop drive, featuring twin counter-rotating propellers.”

 

 

 

Opening salvo: it is about V-6 stern drive engines for 2015

“There isn’t a single GM part on this engine,” Seabuddy quotes Brett Martin, a MerCruiser manager at Mercury Marine. This engine was purpose-built for marine use and delivers Mercury’s proven performance, durability and ease of service.”. All of its parts need to come from Mercury Marine and its dealers. No pistons, rings, cranks, etc are from a GM car engine.

“We are proud to introduce the next generation of stern-drive technology with this ground-breaking new engine,” said John Pfeifer, the president of Mercury Marine. “This engine was purpose-built for marine use.”

Major components of the MerCruiser 4.5L engine include a newly designed rear-facing throttle body, a special anti-whistle throttle plate, engine cover and mounts, lightweight flywheel, fuel supply module and structural oil pan” Mercury Marine has taken the initiative to design a lightweight, high-displacement V-6 marine engine that is not dependent on automotive technology,” said Buck Pegg, from Chaparral Boats The 4.5L V-6 the engine was built with cast-iron componentry wherever the engine encounters seawater and corrosion-resistant aluminum and composites everywhere else. Digital rather than analog sensors are used throughout the engine.

It has been noted that he 4.5L can be installed in single- and twin-engine applications and it is compatible with company’s full series of Alpha and Bravo drives. Fresh design innovations such as a long runner and scrolled intake manifold as well as the higher displacement than the Chevy V-6 , which allows for an good power-to-weight ratio.

Mercruiser marine v 6 gas engine

2015 Mercury Marine new engine

This V-6 engine weighs about 130 pounds less than a 5.0L V-8 Chevy small block, yet provides similar on-the-water performance within a smaller boat. With a shorter stroke than a Chevy V-6 engine, the power comes on higher and one can prop your boat to run as much as 5,200 rpms at W.O.T.
A V-6 engine allows for a bigger cockpit by about 6-8 inches. In a small boat that will make any boat more family friendly than the bigger engine box or sun pad that a V-8 requires.

 

New marine fuel winter storage product

marine fuel stabilzer sta bil 360 winter storage boat

Sta Bil 360 Marine

 

Sta Bil 360 Marine adds new protection to your boat and its engine(s) for 2014. In many parts of the country, boaters have an off-season period. This can last four to 8 months depending on your home port. All you boaters that slip their boats in Key West, well Seabuddy is not talking about your boating fuel habits in a direct way in this write-up.

For the rest of us gas engine seasonal boat owners, let me suggest a few pointers.

Warning, I am not a chemist, I am simply passing on personal experiences and some advertising messaging put out by major players within the marine trades.

Put your boat away with the gas fuel tank 95% full.

At the beginning of your last fill up, pour in 1 oz. of Sta Bil 360 Marine for every 5 gallons of gas you intend to put in your boat.

Think about buying your Sta Bil 360 either at your nearest convenient marine store or at a low price shop. Google search “Sta Bil 360” at Walmart and Amazon.com. Watch your final costs including shipping and sales tax. Use half as much at every fill-up during the season.

Here is a quote from the fuel stabilizer maker “STA-BIL 360 MARINE offers comprehensive protection by releasing a microscopic corrosion preventing vapor inside the fuel system that coats ALL metals parts, including the fuel tank, fuel sending unit, valves, carburetor, fuel injectors and intake manifold. It’s like fogging oil for your entire fuel system, offering “360 degrees” of corrosion protection and is safe to use in all types of gasoline – from ethanol-free fuel to E85.

STA-BIL 360 MARINE accomplishes everything our current STA-BIL products offer, including keeping fuel fresh, removing water, cleaning the fuel system and more, but this revolutionary new product provides an exciting new level of protection for ultimate performance. For the first time, STA-BIL 360 MARINE delivers corrosion protection above and below the fuel line by releasing an innovative vapor that coats all metal parts within the fuel system to prevent corrosion.

Once poured into a tank of fuel, STA-BIL 360 MARINE will provide a vaporized corrosion inhibitor coating for up to 12 months in a stored boat or equipment.”

This product is new for 2014 and it won the International Boatbuilder’s Exhibition & Conference (IBEX) Innovation Award in the Boat Care and Maintenance category.

IBEX is organized by the National Marine Manufacturers Association (NMMA) and judged by members of Boating Writers International (BWI), the award recognizes innovative distinction from other products currently being manufactured, benefit to the marine industry and consumers, practicality and cost-effectiveness.

Bow Rider Helm. Do not miss this one!

Going to a boat show? Take more than a look and sit in, adjust, and observe just how good the helm station is in a 264 FS bow rider.  Study the fit and high level of finish within the cockpit that it leads your eye and hand to experience major improvements that Monterey Boats is bringing to the marine marketplace. Look at the eyebrow over the dash and the gauges. It is as good as it gets for 2014!

This boat has an 8’ 6” beam and is easy to trailer. She has a sweet running hull that takes an afternoon chop well and uses extra power easily. Special hull features are valuable items in terms of performance on the water. See the chine detail for yourself at a boat show. Power this one up. Check the gas tank capacity, also, as a for instance. Ask about these hull design and construction features and decide what power choices will do the job for you. The Monterey Boats 264 FS is a hit in the boating marketplace and a do not miss boat to see at a boat show.

Seabuddy thanks Monterey boats for these photos.

Jeff Hunton 2014 Powerboat coming to US

Offshore racer Hunton designs and builds fast boats for Europe and the Med. He has raced in major races across the pond back to 1975.  His boat designing and fast pleasure craft boat building  started in 1979. Now one of his sport boat designs is coming to the USA.

hunton powerboat go fast 37 marine boat photo image

Jumping a wake shows her bottom shape

She is a 37’ 3” 65 MPH Go-Fast with luxury that has a 8’ 6” beam.  Boats destined for the United States will have 860 horsepower, while, due to fuel taxes, European boats use Volvo diesels. Watch a part of the video… http://www.youtube.com/watch?v=5rrMO3Gldak skip forward to 96 seconds into the 2:21 second video and then watch for a minute.

Hunton Powerboats crafts this boat in Hampshire, England for the bespoke crowd. She is not a racer. She is a fast pleasure boat (or day boat) with overnight (extended weekend) accommodations.  The boat comes with a bow thruster, an electric anchor winch, and teak accents in the cockpit/ side decks. Think Gentleman’s Racer, not boat racer.

The company is well known in its current marketplace, thus the expansion to the U S. This is not an easy market to conquer as it is a big one (with many sub-sections), one that requires that all the electronics, mechanical, and systems be changed here, or installed here by a sub-contractor (thus requiring Hunton shipping incomplete boats across the Atlantic), or all these things shipped in from the U S, installed on a boat, and then the completed boat package being shipped back to the U S. Check for yourself how they are handling this, including service manuals and local warrantee support details.

Mercury Racing offers 1,650 Horsepower Stern Drive for 2014 model year

They also offer 1,350 horsepower and 1,100 horsepower I/O packages for this coming model year.  These are all 9.0 litre engines with quad cams,port fuel injection,  turbo-chargers, and computer controls via special systems that vary the turbo boost as well as run the DTS. It is almost a straight-up, square-torque curve engine with all the items as designed and under control. These are dry sump engines, BTW. WOT is 6,000-6,500 rpms. They all require Mercury Racing Pro Finish CNC sterndrive 5 or 6 blade props that are sold separately. Go to a Mercury Racing authorized dealer like http://tntcustommarine.com/ for more info.

Mercury Racing photo of 2014 model year 1,650 HP marine engine and outdrive

The 1,350 and 1,100 horsepower engines use available marina gas dock for fuel, while the top 1,650 HP strictly requires 112 racing gas. Both of the milder 9.0 liter engines come with a one year warranty, but to somewhat limit the 1,650 Hp engine to racing use only, MerCruiser does not offer any warranty.

There are deals out there for all three of these engines, so do not be put-off by list prices. At the same time, these heads, blocks, and many other features are custom-to-Mercury Racing parts, so do not think they compete with your local engine builder. Think about a cool $250,000 for two engines and drives, as a starting point, but one should be talking speeds over 150 MPH and as high as 200 MPH.

All of these marine engines come with Mercury Racing’s M8 which is a 35% stronger, upgraded drive from the legendary world champion Six Drive.  This is their top performance out drive. Mercury also offers the NXT, Bravo 1 XR, and then Mercury Marine offers, Bravo I, II, III drives for pleasure boaters.

Did Don Aronow race Donzi boats?

Yes, and he won three times in Donzi boats. That was in 1965 and in1966. Don had also won the year before, in 1964 in his 27’ Claudia II. However, #seabuddy would not call his win in 1964 in a Bahamas race in his Claudia II boat as a Donzi Marine boat.

 

claudia

May 2, 1967 the first Claudia race boat. Made of wood. Designed by Howard Abbey.

I believe that her wood hull pre-dated the design team that made Formula Boats, as well as the Donzi Brand team that followed Formula Marine in Don’s stream of boat companies. There are photos of Claudia II inside one of Don’s boat factories, but it was in for service, not construction, in my opinion.

Thus, Don raced and won first place three times in Donzi Boats which was in the 1965 -1966 time frame. These wins were in Donzi Marine boats, either named Donzi 007 or Donzi 008. Both were 28’ Donzi Marine boats.

By the way, the Claudia II 27’ boat design was sold to Marlin Boatworks an out of state boat builder, while a 23’ design became the very popular 233 for Formula Marine which he sold to Merrick Lewis and his Thunderbird operation.

Back to the story subject here, we all know that Don Aronow won 1st place in more than 4 races. So, what boat brands did he drive to a 1st place win in all his other races in?

The simple answer is 27’ Magnum and 32’ Cary brand name boats. The confusing issue is the boat names and as they compared to the boat brands registered with the race organizers of his boats. Second, depending on the race, Don Aronow would race his outboard, inboard, or a sterndrive version boat of the same boat name with one, two or three engines. His six Magnums were named/ called Maltese Magnum. He called /named his Carys The Cigarette as he often had a business deal that kept his name off boats companies or out of being registered as the boat builder of record. Hey, racing is fun and busiess should not slow down racing!.

Finally, Don was named World Champion in 1967, 1968, and in 1969. Plus, he won so many races in that 1969 racing year that his name will always be remembered.
