This question may sound ridiculous to some but I'm puzzled and a little embarrassed.
I just put a '94 Johnson 50 hp back into service after a 2+ year down time due to illness.
I noted no tell tale stream when running on the muffs. It doesn't overheat but there is not a tell tale stream. I've checked the hose and find no obstructions from insects etc. The problem is I can't remember if the stream is dependent on the state of the thermostat or not. In other words does it "****" on start-up or does it have to warm up first? I'm also wondering if I should be able to blow air through the tell tale hose back through the engine or not? I can not do so even with the water pump removed. As a precaution I checked the water pump and out of an abundance of caution replaced it. I have yet to test but will in the morning. I just want to be "armed" with all the information I can gather before proceeding further if the water pump replacement doesn't solve the problem (if there is one).
Also, for another reason, it was necessary to separate the two upper cowl sections and in the process the rubber exhaust baffle grommet cracked. It's OMC part number 0334883 mounted between the lower cowl and the exhaust housing. Can it be safely run in that condition while I search for a replacement or figure out how to mend mine? Believe it or not, there is only one showing in stock world-wide! The guy that has it won't sell it and says he has turned down $180 for it.
What about running it with the crack in grommet it until I can find a replacement or mend my grommet?.
Any advice from you "ole hands" will be greatly appreciated.
