Hi all it's me again. Well I am getting ready to get it out in the river tomorrow to test things out. I put in the new stat and ran and so far ok except for the temp gauge. It reads 180 steady thermostat cyles and it drops 10* then back up to 180*. I feel the sender or gauge caould be bad. I took a plastic container and while it was runing on muffs I held it under the exhaust (spent cooling water) and had a thermometer in it and it showed a constant 120* I would guess there would be some cooling after leaving the engine I might guess 20* which would make it 140* which is what the stat is. Does this sound logical?
If not how can I test the water temp?
Thanks again
