anyone have an estimate of what the 150 HPDI is worth?

Just saw this post go begging and not what you asked but if you are considering a HPDI they have had a shocking run in the US somewhere along the lines of the fict and early OPTi's. Cannot remember which sizes went pop often but info worth considering to see if the technology has been fixed since.

cheers fnq

300 & 250hp have a fairly bad name over there, although the 200 & 150hp are known as a good engine.
I would be looking at an opti over a HPDI anyways.
We priced a 250hp HPDI to be more than a verado (with binnacle, powwer steering & prop), go figure??

The Biggest Yamaha dealer here in Tassie refuses to sell any HPDI Yammies due to them blowing up..They did sell them when they first came on to the market ...but alot of commercial Divers..ect had nothing but trouble with them....As FNQ said ...they are comparable to the FITCH and early OPTI`s...

You have me worried as i have a 175 hpdi and only done low hours but has been good so far.

I have been on a boat with a 150 hpdi recently which has done 350 hours, the owner, the boat is used commercially and the owner has nothing but praise for the motor. However putting this into context he does get some sponsorship from Yamaha but I trust his opinion.

My problem is this, Fuel consumption on my boat is becoming an issue, not the cost of fuel nor the really the consumption but limiting the boats range, being the bigger issue.

I have a yammy 2- 130 on the back of a 5.5 meter glass boat, inside I am roughly getting around 1.5 k's per litre. however when I go outside I have a 70 km round trip from the ramp to the bar. I am finding that when working the boat outside in the swell at the end of the day I am using about 1 litre per kilometre, the tank in the boat is only 150 litres, I also like to err on the side of caution and not push my luck, I usually take a spare tank with 25ltrs.

There have been some interesting posts regarding fuel consumption on boats, I have seen the 150 hpdi on basically the same trip on a bigger boat use 30% less fuel than I would, so am just checking around to see what sort of prices I am talking about to change the engine. Which is pretty worrying given the boat is only 6 months old.

Troy.. As far as i was told from my mate who is a mechanic at a Yamaha Branch..is that for some reason the rings slip/slide on the pistons between 500-1000 hrs and of course this siezes the motor...they had about 10-12 do this in one year so he warned me off HPDI and they no longer sell or recommend them....there was also a year there where Yamaha changed Bearing manufactorers and this also caused problems....dont know if the newer ones are the same or not....Cheers Mick

Ps...There are still a lot of 150-200-225-250 Two strokes being used here privately and commercially but they are not the HPDI ones....

PS...Once the problem had been reconised ..then the owners with HPDI`s that hadnt blown up had them fixed at a cost of the 3000-3500 k to have the problem rectified ..Most of the ones i know of were owned by Abalone divers

The 140 suzuki seem popular on this site, maybe worth a look.
I know a fellow who has a 575 cruisecraft with a 130 2s yam. He also gets terrible fuel consumption.
Have you thought about trying a fin on the motor? They are suposed to help fuel. May be a worth a try?
