I am getting some blow by from the hose coupling joining the riser to a fiberglass elbow which then leads into what looks like a muffler via another hose coupling. I tried tightning the two hose clamps, and just ending up breaking them. I purchase new clamps, installed and still get this blow by streaming water mist.

I purchased some high temperature RTV today, and plan to losen up the hose clamps and squirt some in between the hose coupling, and fiberglass elbow, tighten down clamps, and wait a day to start and inspect for leaks. Does this seem to be a legitimate attack to cure my problem, or does somebody have an oppinion on a better way to do this?

Just to clarify it is not at the riser end of the coupling connection. These are crusader 350XL engines.

The hose itself is probably deteriorated internally. Hoses go bad from the inside out. It shouldn't take much clamp pressure to seal. Too much and you'll crack the coupling.

i agree with bob here, many people dont know it but hose clamps have torque specs too... 60 inch lbs. or 5 ft lbs. seems silly but an overtightned clamp can lead to premature hose and clamp failure or whatever it is clamped to, to fail
