Thanks to everyone on this site! With your help and info, I was able to get this motor running like a top! Carb kits and cleaning, to sync info, to diagnosis suggestions and thoughts.. Invaluable info and help. Thanks again. Took the boat out today and she never even had a hiccup while hitting 38mph loaded with 4 and a full tank in moderate chop.. Glad to have the motor on the 1720 sportsman..
