I have recently aquired the above motor. It appears in great condition but the compression is around 50 pounds per cylinder. As I turn the flywheel I feel a bump I am not sure if it is a valve adjustment, timing belt issue or something deeper. I was looking for a used manual on an auction site and see lots of manuals available for T9.9 W, T9.9P, T,S,W , and others. I would like to order one but am uncertain as to what the suffix is in the model designation.
The ID tag appears as such. The motor also says manufactured 1/08
Yamaha T9.9GELH
6AVK L 1002793
H
I may need to tear down the engine or it may be a simple fix as a sheard key. Any suggestions where to start.?
