hey guys!...well after a lot of google-foo i realized that i was doing something wrong!i never would tilt my engine to positive trim when the engine was off,not in use.i started to do this and it seems the smoke went away.ive used the boat a few times since figuring this out and all is good!///except i feel the motor should spin higher rpm.i only get 5180 rpm.the engine now has 20 hrs on it...overall,im very happy with this new rig!i get 27 up stream fully loaded and 30 downstream with 2 adults and to much stuff!..i got the boat from west boat shop,they are extremly nice guys and would buy again from them!
