Meirvins Engine pull and rebuild
Ok guys as some of you know Mudbug wasnt kind to me and my engine died resulting in a tow of shame (my luck all of the texas crew were riding in the area it happened in).
this ski has been very good to me with 245 hrs of riding with no major problems with the last 175 hrs as a stage III with a b-Kit pulling 80+MPH
My buddy ole pal Dave (txgp1300r) is more excited to pull the engine than me and is going to lend his car and yamaha experience to this project.
He is building a bad to the bone stand since this might be a long project.
For my part I have made up the boards for the stand and today in hope that we pull the engine tomorrow I have removed all the speed parts, the manifold and drained the coolant.
I have never done this extensive level of wrenching and am intimidated by the whole process but with the help of this site and research of threads feel it wont be that hard.
I think first we are going to need tips on getting the driveshaft loose hopefully without the proper seadoo driveshaft tool.
Here we go:
Cant wait to see all the goodies that have fallen under the motor.

glad to see you are getting after it Mike
the motor comes out a lot easier than you think and with Dave's help you will be back at speed in no time.

Might as well pull the intake manifold while you are waiting...that gets the wiring harness out of the way, along with the other items...less stuff in the way.

dont over tighten. Now pull back on drive shaft collar with both hands, hold with one hand, and use the other hand to remove c clip. use a screw driver to help push c clip off. Then your done with the hard part.
