By the way for reference.
If the oil is milky it has water in it.
If it is dark black it has passed its useable life.
Either way. Change it!

Reckon the thermostat should be on your list. Not suggesting you replace it unless you think the block is running hot, but at the very least pop it off, wire brush it, check cooling passage for salt build up, new gasket, etc.

I'd also look at electrical bullet connectors, lightly clean with fine sandpaper and re-connect.

Manual start engines, renew starter rope every second season.

Gear oil, change every season regardless of hours.

If you loosen the bolts on the housing and use a thin strip of metal (I use feeler gauges) in behind the plate, you can wiggle it and work it all the way round. To separate the plate from the gasket.

Then you will probably get the thermostat out with out damaging or ripping the gasket. So it can go back together if all is ok inside

Carburettor bowl gaskets also if you are removing the carbs are pretty good to have also. They are rubber and can stretch sometimes when removing . You can get a carb repair kit for the motor that inlcludes all of the parts and new float needles and gaskets for about 120.

All done and I managed not to break anything!

Spark plugs replaced
Cleaned fuel filter and replaced strainer
Checked all fuel and oil pipes
Greased all linkages
Grease nipples x 3 - greased
Propeller checked spline for wear and greased
Cleaned anode with wire brush
Replaced gear oil
Water pump impellor replaced
Thermostat cleaned and checked (I knew that jam making thermometer in the drawer would have a use!)
Battery old one not holding charge so replaced and terminal connections redone.

Actually quite enjoyed doing it and now feel more familiar with the engine and how it works. Thanks for all your advice.
Cheers
Neil
