Fired up the boat today and the heat exchanger is leaking from the rear. It looks to me as it is the gasket, at least that's what I'm hoping. It was not leaking this bad until I tightened up the bolt about a half turn. LMK what you think. Also how do I go about replacing it. It looks like I would have to remove the hose clamps and move the exhaust out of the way. I would also go ahead and change the front gasket too. http://
