Wraith 5.7L 335+ hp

V8 Small Block Chevy 350cid

This engine is specifically designed for the discerning 335 cid (5.7 litre) owner who needs to replace or is looking to upgrade his basic crate engine(s) for something more sophisticated. If you are looking for a faster, more reliable engine that will put that little extra sparkle back into your boats performance but at the same time improve fuel consumption, then this is the engine for you.

A glance at the improvement in BHP and specification will show that this engine gives surprisingly good value for money. Like all Swaymar special series engines this too delivers a lot more torque and BHP several hundred rpm lower down the rev range than its factory replacement counterpart. Specifically designed for Hi-torque, this engine is perfect for marine applications. These carefully considered engineering improvements result in a considerably faster boat but without the usual fuel penalties associated with more power.

Compatibility

• Mercruiser
• Volvo Penta
• any boat running Chevy V8s

Only suitable for Mercruiser's equipped with Bravo legs. Can be used with most Volvo Penta drive legs.

Recommendations

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

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.
