Re: have you replaced the outboard motor mount ?
I got the Panther 550408SS Light Weight SS 4 stroke, for my 9.9 Honda. I filled the prior holes with Epoxy, after reaming them clean with a drill bit. I glued (5200) a primed and painted piece of 3/8 aluminum to to the inside of the transom (through the Port locker), to reinforce everything. Then I layed out the new mount holes and installed the mount. It was tricky to get the mount located right and avoid interference from the rails. I got my mount from boatfix.com.
