Yamaha HPDI

[Nasher]

At the end of this year I'll finally be at the point where I can consider changing the 1998 Suzuki DT200EFI on my RIB for something a little newer.

The reality is I'll put on whatever used motor comes along at the right price at the right time, but because of the weight limit on my boat it will have to be 2 stroke and preferably ETEC shaped. Budget will be up to @£6K.

One I'd consider is a Yamaha 200HPDI.
However whilst enjoying a sneaky après-gym coffee in the gym bar today I was reading an old copy of Powerboat and RIB that happened to be in the bottom of my Gym bag, and in an article on used Scorpion RIBs it said boats fitted with a Yamaha HPDI were best avoided. There was no further explanation.

I've not heard about anything particularly wrong with them, and wondered if anyone had any idea why such a sweeping statement could be made.

Surprised at that, if you head over to THT forum you will see the yanks love those engines in 200hp guise, the bigger ones were not so good apparently, perhaps giving some credence to your mag article. Perhaps as they were one of the first to offer direct injection the mag preferred the carb version of essentially the same engine (ox55)

With that said, with a healthy budget like that you can literally have anything you want, etec, optimax etc.

I think stu is suggesting that these were known as "high probability of destructive incident".

Thanks all

Found the Ribstuff site recently, and have it bookmarked as they appear to have some good deals in place.

Unfortunately it will be towards the end of this year before I can contemplate it.

With regard to the HPDIs, I've done some trawling about, and The Hull Truth (thanks Xk59D) appears to confirm what I've now found elsewhere, in that the 150 and 200 appear to be as reliable as anything else, but anything over 200HP deserves the bad reputation.
The article I was reading did I believe relate to 225HP and 250HP engines, so it makes sense now.

Hi,

I've had 3 clients who had "power head" issues with their HPDI yams (requiring complete new heads), but IIRC they were all the 250hp variant.
