Yamaha 300 HPDI

I know that this engine had some terrible problems when it was launched which seem to be related to slow running. I am now seeing a lot of them fitted to boats in the US and new some new Scorpions and assume that Yamaha may have them sorted.
Does anyone have any experience with them? Gavin

I heard from a Yamaha dealer that Yamaha is no longer going to sell HDPI outboards in Europe. From 2007 onwards, they will sell there stock and stop with them. They will only homologate the four strokes in Europe.

If that's the case it might mean cheap engines but not much support. Pity, as I like the idea of a high quality and relatively lightweight 300hp 2 stroke. Gavin

If you want a lightweight 300 look at the new Mercury 300xs - much lighter than the Yamaha. Also the suzuki 300 4stroke is pretty light - not much more than the Yamaha.

thanks for the Mercury link. I find their range confusing in that they are billed as race engines. I am very pleased with our regular 225 Optimax but am wary of using a racing engine for recreational boating which may involve an hour at low revs following a yacht race, for example. Or am I beling confused by their marketing.... Gavin

Yes I think you are - it is marked as a "consumer engine" - still has a good guarantee etc and complies with all the emmission stuff.
