The serial # tag is missing off of the motor. The serial # on the freeze plug is A949467. The title says it is a 94 Mercury 50 hp. I had to replace the lower WMA3-3 carb due to a bad needle valve seat, and after a lot of time on the web I believe the engine is a 1986-89 but would like to know the exact year.
I purchased it last year on a 95 Voyager 20 ft pontoon. It had 12 pitch aluminum prop on it until we hit a rock. My boat partner replaced it with a used 13 pitch Stainless prop and it seems even more under powered than it was before. The compression is excellant on all cylinders, and it starts, idles and runs fine. It just has trouble coming on plane unless someone sits up front, and it seems to have lost some top end speed. The engine tilt pin is set two holes up from the bottom.
From what I've read on the web should I probably have a 10 or 11 pitch prop on it? Will this help or is this too small an outboard for my pontoon?
Thanks in advance for any advice!
