bought this 1982 larson last winter 25 foot dc with and omc stringer drive. i installed a rebuilt 350 with some extra horses and the boat ran like a top all year. first time in years i have been able to just get in the boat and go. no worries. I want to make sure my next summer is just as successful so winterizing is important. I have already pulled the plugs on the motor and drained all the water out. now what? what can i do to the drive if anything. I know its an old drive and I would rater not chance it. drain the fluid ect..... i known nothing about these old drives all i know is i want it to continue to work. i know parts are hard to find for this dinosaur of an outdrive. thanks in advance...
