    My mechanic gave up! Need HELP!

    I went through all kinds of major steps and expense to fix this. I used a master mechanic and wasted a lot of time and money- I would say over $5000 in parts and labor. To no avail. The hours on a motor mean nothing to me now. It seems like in this case it was more about the age (19 years with...

    My mechanic gave up! Need HELP!

    Thanks for your smart advice. I do have faith in the guys that are repowering my boat. The drive that was on it was absolutely fine. The new one has less than 10 hours on it. There was some weird fuel injection issue with this 2 stroke Yamaha, an HPDI model.

    My mechanic gave up! Need HELP!

    Thank you. I put a brand new lower unit in last year in an effort to solve it that way but no. There was nothing wrong with the one that was in there. Now I am thinking about taking that new one back out and selling it before my engine is wholesaled off for next to nothing. Not sure if I can...

    I have to say that I never moved it past because I was afraid the engine was being damaged, and it sounds like it is going to explode. It's knee jerk to pull it back I am sure you understand too. I also think that would have done nothing because the engine isn't listening to the control input...

    The gauges are crap. The only one I changed so far is the fuel gauge because I was working on a fuel issue as a possible problem in this and ruled it out. MPH isn't connected.

    My mechanic gave up! Need HELP!

    The boat ran normally when I bought it and for the years that 2 previous owners used it. I am the one owner that this issue came up on. It is not transom height or props. I appreciate you even thinking about a solution for me. FYI here is what seems like the best response (to me anyway) from...

    Nope 3 perfectly good props tried and the boat was used for years with the engine as it is mounted.

    My mechanic gave up! Need HELP!

    Yes it was doing the same thing at the exact same point in rpm/acceleration every single time.. There was nothing wrong with the other lower unit. I replaced it for no reason in an effort to fix this problem. "despite the engine RPM increase you say that forward motion doesn't increase (speed...

    Thanks Guys - you are right. --to be exact this is a 2005 Yamaha Z200TXRD Here is the serial number- 6G6X1020793 It is definitely a 2 stroke HPDI. My mechanic has gone through the motor extensively. I have owned this boat going on 4 years. Prior to that it was used by another guy for...

    My mechanic gave up! Need HELP!

    Hi guys. I have a 2005 Yamaha Model F200 V6 It is HPDI version and is mounted on a 24’ Sailfish WAC. This engine has less than 600 hours on it. My problem is that the engine runs absolutely fine until I get to around 3500rpm and then it races. I will post a video here to show you. My mechanic...

    Pretty sure my gearbox is toast..

    Hi All- I have a 2005 F200 V6 Yamaha - fairly low hours on it but I think my gearbox is done. I get to around 4k rpm and then the engine races and I lose forward motion. I can putt around at low rpms all day but on acceleration it does this and seems like the clutch slips outta gear. I am hoping...
