Force 9.9hp to 15hp Outboard Conversion Questions
What exactly is involved in converting a 1989 Force 9.9hp (model 92F9A
Serial 1097) to a 15hp? First, is the bore stroke the same? Head/compression ratio? Carb? Timing? Any comments? Thanks, Marko |
For most motors, it is just about cheaper to buy a 15 hp. Check with a
dealer to be sure, but most need new carbs, reed valves and enlarged exhaust. -- Bill Chesapeake, Va wrote in message oups.com...
