Perfect for pottering around waterways. The MerCruiser 4.3L MPI makes good economic sense in infrequently used sportscruisers. The exhaust note is nowhere near as satisfying as a V8 but under load the V6 noise ain’t half bad!
Is the MerCruiser 4.5 a good engine?
At 250 horsepower, the MerCruiser 4.5-liter is nearly on par with some of the lower-end V8s. Second, it does so with two fewer cylinders, so it’s more economical. It also weighs less, which is important to fuel economy. And, again, it has been designed from scratch to be a boat engine.
Is the MerCruiser 4.3 MPI fuel injected?
Power steering is standard, providing you complete and effortless control.
|HP / kW||220 / 164|
|Fuel delivery system||Multi-point Electronic Fuel Injection (MPI)|
How fast will a 4.3 MerCruiser go?
Our test boat had the base level power of a MerCruiser 4.3lt V6, which is a carburetted engine rated at 142kW/190hp fitted to an Alpha drive unit. That gave plenty of get up and go, with a 75.7km/h top speed.
