I put a 500hp in my 22ft advantage and it has no t stat. I ordered the water crossover and the t stat housing from Eddie Marine and wanted to know if i am supposed to run this motor with or without a T stat. Thanks Jeff.

I would run a 140 high flow stat. But if you have water pressure issues then you will have to run a restrictor. You should be fine with the high flow version though.

Is that why it doesn't have a t stat now, for more water flow. I am not sure what temp the T stat is that Eddie Marine is sending me in the kit. What temp should my 500hp run at.

not running a t-stat or circ pump can cause steam pockets to form in the back of the heads. I would drill your intake (rear water ports)if you don't run one.

140-160 is a good range to run (non efi)
