 I took the powerhead off the Merc 3.3hp engine tonight and followed
the entire cooling system throughout, checking for any blockages.
There was none. I also discovered there is no thermostat on the 3.3
hp. I didn't think there was, but I'm a rookie with engine repair so I
wasn't sure.
 When I opened up the powerhead I found plenty of fresh water still
not dried out. Indicating to me that the powerhead was getting cooling
water but for some reason it just wasn't coming out the water pump
indicator hole. Which I did clear out with wire when I was trying to
run the engine in my back yard. Everyones suggestions on these posting
I did check out. Still nothing. This is the damnedest thing.
