5.0L 280bhp V8 Performance Marine engine rebuilds Whilst at first glance the improvement in BHP may seem modest compared to its standard factory counterpart, it should be borne in mind that this improvement in BHP, and crucially torque, is in both cases at several hundred RPM lower down the rev range. These carefully considered engineering improvements give the driving impression of a considerably faster boat but without the usual fuel penalties associated with more power.

Recommendations

5.0L 280bhp V8 Performance Marine engine rebuilds We strongly recommend to all of our customers to consider trying a 1 piece stainless exhaust system and do away with the fear of leaky cast iron ones ruining your engine. You can find more detailed information on stainless steel marine exhausts as well as independent articles written by marine surveyors on the pit falls of cast iron manifolds at stainlessmarineexhausts.co.uk.

Propeller Pitch

5.0L 280bhp V8 Performance Marine engine rebuilds Depending on boat, in order to prevent over-revving, and feel the full effect of its extra torque, this engine will probably need to carry a larger diameter or coarser pitch propeller.
