Super Goon At Large
Ok gang I have a problem that maybe you can help with. I took my boat out yesterday and all was ok until it got good and warm thru and thru. Then the starboard motor would idle ok but when I tryied to bring it up to say 900 or 1000 rpm it would just stumble and carry on, if I kick the throtle on up a bit it will clear up by about 1100 or 1200 rpm seemed to be fine. I thought I was feeling a slight miss but it was hard to tell for sure thou. My first guess is spark plugs or a bad wire/distributer cap? any ideas as to what else it could be? oh yea it is a 454 mag with carb.
