Turns out, it's not that difficult.
First ,get the new Thermostat.
I recently had the outboard shop fix the seized choke. I didn't know it was the choke, but they figured it out in less than an hour. Now the engine run really well. It just doesn't pee, almost a slow drip.
So I asked them if they had the parts for a Thermostat replacement and, while I'm at it, how about parts for replacing the water pump impeller.
In stock, OEM brand, I picked them up an hour later.
Back in my garage, I removed the engine cover and got down to it.... changing the Thermostat.
The Thermostat is housed under the Throttle control linkage.
Turns out that I just needed to unscrew the two bolts on either end of the housing.
The housing was firmly held in place, it took a few taps with a leaded hammer to break the gasket's grip.
Then it was easy to lift the housing out of the way.
Looks pretty grotty.
After prying the old Thermostat out of the housing then, using a razor blade, I cut off the remnants of the old gasket, and cleaned the surface with wet-dry paper.
Next repeat the cleaning process on the housing cover.
Next, I replaced the gasket , housing cover and Throttle linkage but did not install the new thermostat. so that I could run the the engine.
With the engine outside attached to the water supply, I ran the engine, still no peeing.
DUH! I used a piece of wire to clear out the weep hole. Woohoo,
Next, flush the engine with salt remover. Left the engine running for a few minutes then , back into the garage, I removed the Thermostat housing, inserted the new Thermostat and buttoned everything up.
Back out side, connected the water and flushing kit. Ran the engine which now pees like a teenager.
After ensuring flushing fluid and let it sit for couple of hours.
The whole task took less 2 hours plus the flushing and now it's ready to put back on the boat.
Looks we're ready to see you on the water.
