I have a 1979 mariner 9.9 I recently replaced the impeller put it all back together and no water from tell tale I then put it in gear but still nothing I noticed the prop was not turning either so I took the powerhead off and the spline in the crank was stripped does anybody know of a fix for this short of replacing the crank this motor runs perfect and I would like to keep it Thanks for any help RASTADOG

Re: drive spline

That's too bad. If you could get the crankshaft out of the motor, then MAYBE you could have the spline end/area welded and machined/reworked to accept the end of your drive shaft(which you might also do some welding/working on). As long as the 2 engage together sufficient to transfer 9.9HP. The engagement needs to be good or it could create vibration or noise. With a small HP motor this could work! I know you hate to just trash a real good old motor like that...go for it!
