Hello all I picked up a boat last week it's an older one (1985) with a 120 mercruiser. We put it in the water this past weekend and found a lot of water under the motor after just a few min so after I drained the water I backed the boat back in the lake and watched down around the motor area no water than started the motor and found water to be coming from the bell housing area out from around were the starter goes in. If I run the motor in the drive way on the muffs I get no water. I did find water in the drive shaft bellow but for the life of me can't find any holes in it got any ideas thanks
