I went out with a friend of mine this weekend on his 14 foot jon boat; he has a 9.5 hp johnson on the back. He doesn't have computer access so I told him I would write in for him.<br /><br />It would start alright and run ok at low speeds but when he went to speed up something was definitely wrong. The RPMs would increase but the speed stayed the same. The only other thing I noticed was a good amount of white smoke.<br /><br />Any suggestions?
