Problem with Opti 115

[Slinger]

Just wondering, could you just take the thermostat out like in the old cars, and let water continuosly circulate? At least that would give a definite answer to if it's the part.

It worked! Put a wooden block on the housing and gave a few taps, waters squirting out like a long necked steamer! Thanks for all the advice, saved me a bundle. The Trout thank you too, they've paid a heavy price for the boat being laid up!

...and I get laughed at everytime I hook the hose up to the rinse out connector on my Yami 4 stroke. I rinse the inside of the motor for 5 minutes with fresh water so there is no salt build up.

More than likely the poppet valve was stuck, not the t-stat.... the water that is alllowed to pass by the t-stat dumps into the itermediate housing after flowing past the exhaust chambers and exists out the lower unit and acts as a muffler when it fills the tube ...it's a good practice to replace the poppet valve diapram, t-stat and water pump every 3-4 years ( I do mine every other time I re register), it's not just the use, sitting idle causes the impeller to take a set, the poppet valve also can stay seated in it's seat, and the t stats ( which are very small), get plugged and corroded..glad you got it working..
