Aloha. I am looking for any feedback on the Yamaha HPDI 150.
I have a 18.6 Gaurdian that it will be powering.
Much Mahalo

I see no one is jumping on this one. I don't know anything about HDI Yamaha's but have heard good thing such as thye are best engine in that type of injection. I have a friend that sells Yamahas so his opinion would biased. His only statement asked about a replacement motor was that I sell Yamaha's, but make my living working on Mercury engines. Just my 2 cents!

I have been looking for feedback and not able to find it here or other places. Our dealerhas nothing but good things to say about them, but then again they have only sold 2.
I'll keep looking.

I've had no expirience with the 150 HPDI, but plenty with the 200 HPDI. My brother has one on his 22'.
A real great motor. Quiet, no smoke, easy on gas and oil.
Never a problem...quite impressive.
I would assume the same for a 150.
I have a Yammie 250 OX 66. Not nearly as fuel/oil efficient as the HPDI (I wish the hell it was)
All in all, I think Yamaha makes a great product.
In the area where I boat in the Northeast (Cape Cod) they own the water....

I only know one person (my close neighbor Dennis Hall)who has had a Yamaha 150hp HPDI and it was on a 22' Pathfinder CC. He used it for about 6 months and after some problems (I don't know what) it blew a power head. He said there was metal shavings in one of the cyls but dealer didn't really explain it to him. He traded for a Yamaha 150 four stroke.
