This motor was given to a friend, It has set up for two or three years. The previous owner must have gave up on it...w/ new fuel and "sea foam" additive, it starts and runs fine. When I run it, it sounds rough and will not power my 14' boat like it should...in fact, my 9.9 converted to 15 will run circles around it. it shifts great, and doesn't bog down at all, just won't run fast like it should...not good acceleration either. Where do I start? is is possible to be running off 1 cylinder? Maybe just a clogged high speed jet? How is the easiest way to get carb off? Also I'm trying to figure out what year this motor is...Ser # OB294911, electric start, tiller handle. On my little 14-36 boat, (20 hp rated), this motor should be too much, but is not. Where to start? Any easy ways of testing these things? Also the Choke does have a little affect on the motor at idle, but takes a minute to choke it dead. Also the kill switch doesn't work. Any help would be great. !!
