im looking to build a 90 hp yam gravel bar drag motor. il put it on a 16 ft, .60 guage alum jon boat. my boat already has a tall transom, so i will probably keep a 20 mid on the motor with t/t. im wanting some ideas about some intake mods, along with porting and exhaust. i dont know if ill rig it for steering or tiller? any and all advice welcome
thanks
