Got a problem with my CC Dory engine. Looks like it's been leaking water from the underside of the starter up where it bolts into the bell housing and runs down to the end of the starter into the bilge. Water leaks most at idle , a good trickle, then goes away 1ooo rpm and up. Engine runs great, all oils clean and free of water. It's a GM 350 , btw. Engine water temp has been a consistent 175 F at 1200 rpm or less; 185 or so at 1300rpm on up all summer. Is this a big problem or can it wait till winter for me to fix? And what do I fix? I realize it IS a problem and not right.
