[QUOTE="Johny25, post: 248121, member: 7791"] Well lucesco I know some of those years you are talking about had different gear cases which could cause a problem when putting 10 to 15 more HP to them. You would have to cross reference to see what the differences are for what year motor you are talking about. I know I was talking to someone with an 80' or 81' and the 20hp of that year has the smaller split gear case than the 35hp. Would hate to see people doing this mod and ripping their gear cases apart so look into it. Or ask and maybe I or another can help you. [/QUOTE]
