Man Spare, we must be on the same wavelength. I slept on it and thats what I thought about! I'll try running the bathtub half full of really hot water and putting a little air on it. I just put a new riser/tank on it, and thinking about it, looks like the whole exhaust manifold and riser would have to fill completely up before it could run over into the seawater pipe on the riser and back down into the heat exchanger (I think). Its gotta be the heat exchanger, I'll let ya know what I find out. Thanks Spare!!

I found my leak. I capped 3 of the hoses and made up a fitting for the last coolant hose. I put on one end cap and stood it up on one end and filled the seawater chamber with hot water. Then I put about 20lbs of air to the remaining hose and instantly I could see the bubbles start coming. It has a pin hole on the plate that goes across the end of the tubes. I might be able to braze it up. I think Ill give it a try before I buy one. Im just glad I found it. Thanks guys for your input!!

don't braze, you'll have to get it too hot, use solder with a pin point mapp gas torch

I bought a new oxygen/mapp gas mini torch at Lowes yesterday and finally got to use it today. I had a little trouble at first trying ta get the solder ta stick, but after cleaning it really good and giving it another try the solder flowed out like butter. I put 40lbs.of air pressure to it and after sitting about an hour, it looks like I got my leak fixed. I'll put it back on and give it a try.
