Just bought a 1979 Baretta Bowrider it has a Mercruiser 140 ho 3.0 and if I understand the lingo it is a sterndrive? My question when I bought it some one had but on a chevy starter from a 2.5 big starter compared to the original. New battery, new starter but still wont crank over. I can turn the motor over by socket and ratchet on alternator and pressing the belt, it does turn but seems real tight. Here's the big?????? doe's this thing need to be in neutral or something? Seems like I'm trying to turn over a car in gear. The wood rot is terrible but I can deal with that in fact the front motor mount had gone through the floor and the engine was tilted so bad forward. If I can salvge the motor I want to pull it redo transom and floors the boat shell is in good shape. Thanks for any help or comments
