Anyone know if this engine is a better choise than a yanmar 315 on a revenger 29?

Itīs only 4 cyl and i must save much weight compare to yanmar... Or what do you say....

The Volvo weighs 669kg with a sterndrive - the Yamaha ME432TRP 315hp weighs 567kg. Yanmar quote their weight without sterngear.

Given that Yanmars frequently break Bravo drives and that Volvo have developed their latest drives to handle the output from the D6, it's not too difficult a decision if reliability is important to you.

Yes Volvo drives are pretty good - don't hear of many problems with them.

Cant help with the weight/drive questions but I have done a couple of hundred hours on a D6/300 and on a D4/260.

To my surprise, the four cylinder D4 is equally as smooth as the D6. I happily confess to being "anti-volvo" and preferring the Sabre-Perkins range - but it needs saying that these two engines are absolutely splendid.

I'm sure the D4/300 will be just as good.

Although some say that this is taking just too much out of the block - its a 3.7 litre engine - so its not exactly tiny.

We are dealers for volvo penta as well as yanmar. the warranty for volvo penta is much better. it is a lot easier to get warranty work done with volvo, yanmar tends to drag thier feet, at least on this side of the pond. parts also seem to be much more available for volvo.

Thanks, and about fuel economy and speed.

I donīt know the weight of a yanmar leg but say that you save 100kg with volvo? And 100kg must be close to 15hp?

Do you think a can get a revenger 29 stepped hull to get 54knots with volvo? Revenger say yanmar 315 will do 54 knots....

62mph with about 300horse in a boat nearly 30 feet long carrying over half a ton of diesel engine sounds a bit optimistic to me. It must be light and empty.
