    305 to 350 build questions

    Well the first season on the new motor is in the books. Winterized last week, and put away for the year. Ended up putting 48 hours of run time on the new motor. Really have nothing much to complain about! I think the oil leak is the front crank seal. I might buy a new balancer and see if...
