2006 250 HPDI owned since 2007 with 48 hours on it... I lost #2 at about 490 hours. All original... Not 1 single problem until the end of 2016 when the cylinder torched. NEVER ran any conditioner or...

Thanks for the follow up post sir... good info. Good thing you did not pop a cylinder running lean... that's what happened to me... Best of luck going forward...

I use the Lock-N-Haul. It's will fit about any motor, light weight, durable and very well priced. Locks the motor if installed correctly and you don't need steering clip.Check it out...

Yes.. photo… You may want to also scope #1. End of 2016 I lost my #2 and part of the piston shot over to #1.. guess since they share a port. No damage done to it but instead of cleaning and scoring,...

Following... same type of issue for over year and half now... tech is done trying to figure it out. "ALL" my filters done... rebuilt injectors, new injector, new fuel lines, coils checked, different...

I'd say there's still a little market out there. I see them being sold still and folks are interested in posts where they are for sale. You can check the motors for sale section and search HPDI to...

how did you find out it was the ECM if the other shops missed it? Was there a special test or did you happen to just try a borrowed ECM and it solved the problem?

Following... had same prob for almost 2 years now... GOOD LUCK ~

so, was it actually the HP (mystery) filters? Prob solved?

how much was the rebuild for the HP pump? do you recall?

Yep, I know what you mean. My tech hooked mine up to the computer 3 times and all looked good.. but there's something happening while under a load running. He thinks it's something with the HP pump,...

following this one for sure... same exact problem after having cylinder rebuilt. I've done a list of things as well... tech finally said he does not know the prob. I've been told it could be my high...

Bummer man! Yeah, new injector did not work for me either. l was having 1 additional problem along with the RPM/speed issue and that was 1 plug in #2 kept fouling.. I mean every trip the plug would...

Fingers crossed for ya man... still watching for your fix and hope it translates to mine... haha... Good Luck sir ~

Brad, please post if you figure it out... been having the same issue for over a year and tried everything recommended that worked for others, but not for me... guys here are GREAT with all the info....

Here's what I did...
lower the front of the trailer down so the back of your boat is a little able level... this helps keep the fluid in from running out. I'm assuming you know where the trim fill...

Thanks much to both of you.. this really helps point in a direction... love this site!

2006 HPDI 250 - ran fine all morning with several stop and starts from running to fishing spots. about 5 hours into the morning went to start it to move spots.. the beep came on with key turn as...

Been having same problem since 10/2016 when I had cylinders 1 and 2 rebuilt. Hope you find your prob out... I've gone thru several things suggested by this board that worked for others.. but nothing...

I think the cowling will say series 2 on it, if it actually has the decals on it. I'm sure others will advise how to check via the number or something. Since you're new to Yamaha... they usually...

Yep, my tech swapped out the injector filters before I got to the shop and I watched him do the HP fuel pump filters... and I bought 10 of the filters from the injector guy in my area and they were...

This is the info I found, which were the ones I purchased from a fuel injector repair/test guy... my tech installed in injectors as well as HP fuel pump... You could also either remove one of them...

I have an 06 250 HPDI and on mine the basket filters for the HP Fuel pump(s) were the same as the injector filters. I don't know the measurements, I bought mine from local guy that does injector...
