I have six bolts out of the powerhead, but it is not coming apart yet. I am trying to separate it from the foot. Are there more pieces I need to remove before I can get the powerhead off?

Glad to have finally found this gang to ask for help.

If you have all the bolts out, could be the d/s splines are stuck in the p/h.

remove lower unit,
between powerhead and midsecrion is a gasket.
this gasket acts as a gleue.
the idea is to break this tension

Is this mtr used in salt water ?? 'cause I never had to drop a g/c to get the p/h off. Try dropping the g/c and if you can get it off you'll know the splines aren't frozen.

Yes, the engine is used in salt water. It seems the shaft doesn't turn the pump and the gearbox. Don't know if the shaft or the splines are stripped.

I'm going to try removing the g/c. Let all of you know. Thanks for the tips.

I've got the powerhead off; thanks for confirming that I had all the bolts out.

It looks like there is wear between the shaft and the crankshaft and the shaft doesn't turn when the crank does. Should I try to fix this thing or toss it?

9.9/15 hp. powerheads come up on ebay frequently and finding a d/s shouldn't be too difficult if you want to go the replacement route...look at the top of the Forums under the Top Secret Files for Salvage Yards as well....

Thanks for the leads. I'll check the file and ebay; I won't throw the engine in the bay just yet.
