How's it going? I think I'd consider using a multi channel scope/logger, e.g. picoscope etc, to help diagnose. Have a look at the picoscope web site to see some of the approaches they use for diagnosing cars. there's some clever people doing smart stuff, much of which could be paralleled on an HPDI.

Hi, did you get to the bottom of this in the end?

Still no further forward on this and thinking towards next season.
Last request for help - does anyone know anyone in the UK who truly understands how the 150HPDI works and might be willing to look at mine?

If you havenít had your injectors properly cleaned then Iíd recommend this prior to doing any further work. I also have a 150 yam and my friend has a 115 yam, heís had the same issue you describe and it was a low flow on the injectors. If you can remove them, then post them to Rock Marine Services in Cornwall (no I donít have any connection with them just a very satisfied customer) they can flow test and properly clean them for you, theyíll also give you a report on the flow rate before and after cleaning. Itís surprising just how the tiniest bit of a blockage can stop your performance. Iíd also recommend a new Oíring kit before refitting especially if the injectors have been out a couple of times. Hope this is of some help to you. Good luck

Wherever you take it you'll benefit from providing a detailed explanation of symptoms & diagnostics undertaken plus results. It might be a worthwhile exercise posting that here as a consolidated statement- many won't trawl back through 4 pages.

We had maybe 10 or more 150 hdpi engines

That was many years ago. Last ones used maybe 2004. They were basically bomb proof. Ok the Filter in the VST needed changing and the high pressure fuel filter you threw away but that was basically all our problems apart from cylinder head gaskets at about 1800 hours.
Philip from Yampower, Glasgow sorts all our engines and continues to do so.
Glasgow is a long way from the south coast
