Volvo 375 Hp and more at the boat show

8.1 power boat engine from Volvo

Volvo makes an 8.1 gas big block engine for the most torque and horse power for a power boat. Volvo has been a leader in marine pleasure boat power in the USA since 1959.

The 8.1 engine comes with a choice of camshafts that are selected based on where you as a boater want your power. Use 4,200 rpm and above mostly and pick the high Hp cam, use 4,000 rpm and below for almost all your time boating, select the 375-400 Hp engine cam. So, a true “hot rod” boat speed freak boater best uses the high performance camshaft and everyone else should use the regular cam. It is a no brainer, really, as you know going into a boat show if you want the most power you can get out of the engine below 4,000 rpm (even more power than the performance cam at these “below  4,000 rpms” engine speeds). Remember, the 375-400 Hp engine is the “Hole Shot” engine choice for the quickest 0 to 30 mph acceleration tests.

Either the 375 or the 400 Hp engines are rated to run as fast as 4,600 to 4,800 rpms. They just do not develop as much power at those rpms as the Hi-Po camshaft engine.

All of these engines are 8.1 in displacement or big cubic inch engines developed from a Chevy based v-8 engine. They are fuel injected engines using a MPI fuel delivery system. Fresh water cooling and  the drive system is separate choice.
