Thermostat bye bye???
I hate to wait for my tell tale to show, I always get paranoid that the thermostat has got stuck and the engine will over heat. I did this with jet skiis so I am assuming as its a two stroke too that I can remove my thermostat so the flow of water is constant. Lets be honest I am not exactly driving it in icelandic waters. Anyway whats the score ladies, can I remove the thermostat??? Has anyone else done this?

maybe but you might find that the engine will run too cold and too cold is just as bad as too hot.

I think only worth removing (and replacing with the "right" size restrictors) if you're going to run the motor hard - ie a race motor.
If you want to do something to make yerself feel better, mebbe drill a small (1/16") hole on the thermostat so there's a partial bypass of it.

hmm yeah maybe drilling a small hole in the thermostat would be good. I think the problem is that I am still awaiting a water pressure sensor and that until I get that I wont know that the water is flowing the way it should.
Heres an idea what about a liquid nitrogen cooled engine

Nope - new ones are more likely to have an initial problem than good service existing ones.
Boil them - ie drop them into hot water to test their speed response at opening and then how much they open.

If you boil them (100 deg C) you might stick em open, or bugger them completely, as they'll be opening well before that, probably in the 60's deg C range.
