    Re: Yamaha 200 HPDI Tear Down

    I finally got a chance to complete my motor tear down and rebuild this weekend. *She started right up and purred at 700 rpms for 15 minutes while I checked all of the oil lines, fuel rails, injectors, and sensors to ensure all was good. *I also bought the Yamaha Outboard motor diagnostic tool (similar to OBDII for cars) to connect my laptop to the motor. *This allowed me to monitor the sensors and immediately notice any error codes if they were to arise. *The tool has a lot of nice features for performing individual component tests on the motor while it is running or just the key in the on position. *It will also inform you of the number of hours on the motor, etc. *My motor had 244 hrs on it when the #4 cylinder went. *I spent the extra $600 in parts to go ahead and replace the fuel injector, all thermo sensors, and reseat the fuel injectors on the port side with new gaskets. *It's been a great learning experience and I'd be glad to share the info I've learned as it's needed. *Just shoot me a PM or whatever. *I can also use my Yamaha outboard motor diagnostics and monitoring tool with the laptop on most Yamaha motors today. *Just give me a shout if you don't want to have to drag your boat to the dealer. *I will gladly help you out in exchange for a beer and small contribution towards the $250 cost of the tool.

    Thanks again for all the support. *I now begin the process of idling around for hours to break in the new piston/rings. *Fortunately I'll be able to monitor all of the engine parameters on my laptop while doing so to be sure everything is going smoothly.

    Thanks, Swimbait! I couldn't have done it without your references and contacts. I sincerely appreciate it.

    I'd like to hang onto the manual until I'm past the break-in period. I'll make sure you get it back. I'm going to order me one to have for the future as well.
