Dwight:

A friend has a Universal in his boat, and he had the same exhaust leak problem.  What he didn't realize was that the water also leaked backed in to the cylinders, and froze up his engine.  You might want to look at that, apparently it's a common occurrence with a leaking exhaust elbow.

In dealing with my fuel pump replacement I discovered that the exhaust system is in dire need of repair. Has anyone with this engine ever tried to remove the flange that connects the exhaust pipe to the exhaust manifold. My exhaust pipe has broken and is leaking black exhaust gas and now copious amounts of water into the engine compartment. It is attached to the manifold with 3 bolts (studs). The upper 2 bolts are accessible and after a  couple applications of penetrating oil (50/50 ATF/acetone) I was able to get them loose. The 3rd bolt however is hidden and it seems I may have to remove the heat exchanger to even get a 14 mm wrench on it. I am hoping someone may have discovered a “secret” aside from turning the job over to someone else. --
