Color me noob- Finding common leaks

[Mslocum62]

Good day all,
I'm a first time VP inboard (or any inboard) boat owner, I've always had outboard engines.
Last year being the first year of ownership , I had to pull out of my slip in mid October, had two back surgeries in November and I wont lie, I had no idea of the winterizing process.... Needless to say, this new season is off to an expensive and labor intensive start. New exhaust manifolds, we had to pull and reseal the heat exchanger...... things are fairly well buttoned up but there's still a leak that I can hear towards the transom side of the engine (the back). Causes the bilge to run about every 90 minutes.
I just bought an inspection camera and tonight I'm going back going to look some more.
Given the circumstances I was hoping someone might have some good information as to the most probable place to find the leak.
Thanks in advance for you time.

Ouch . . .
and Welcome to iBoats. . .

Since you had freeze damage to the exhaust manifold and H.E. there are probably other parts of the raw water side that experienced some damage.

The inspection camera will help because many areas are not easily viewed. Also, get yourself the parts diagram of the engine's cooling system to get an idea of the parts/fittings that might have been damaged.

If you tell us what year, engine, and model it will help too

Pull the drive and inspect the bellows
