I think this outboard has decided that its role will not be to putter a dingy around, but to teach me about outboard mechanics instead...!
Thanks - as always.
Oh dear, back to the drawing board. First thing to check is it heating up? If you see steam coming out of anywhere, it is likely the flow is being impeded.
After running for a while you should be able to touch most parts of the power head without burning yourself. Better yet, use a hand held infra red heat sensor. Anything over about 160 degrees is suspect.
Check the pee hole with a wire, then check the thermostat, put it in a pan and bring up the heat. It should open at about 140 to 160 degrees. there may be a small bypass hole in the thermostat housing that should be open.
If there is a lot of debris / deposits in the thermostat housing the other water passages may also be plugged. Last resort is to pull the head and clean them out as best as you can.
Or, maybe, you installed the impeller backwards? even so, it should/may pump some water? A good shop manual should show the proper mounting specs. Make sure the water feed tube from the lower unit to the power head is clear. I had a Johnson 6HP 2 stroke that plugged up right at the power head to lower unit joint because when the motor was tilted up it didn't thoroughly drain out. Try the easiest things first.
Let us know what you found.
