Merc high temp alarm?

[dbetterred]

I replaced the impeller and the bucket it comes in but not the plastic housing. I thought it looked straight... I might half to pull off the lower again to check.

Never heard of a poppet valve. what is it? what does it do? I'll look in manual after work and check it out.

I thought of the t-stats also, but wouldn't they stop the pee stream if they closed up? They are easy and pretty cheap. I'll get them anyway.

Thanks for the quick response!
