" Jupiter,
About how much doe

" Jupiter,
About how much does a thermostat cost? I am thinking of replacing mine on my 15 Johnson. I'm also planning to rtemove and clean the bolts on the exhaust manifold and block. They are badly rusted. Is there anything I need to be careful of? Proper torque is 15-20 ft-lbs right? Is the sequence important? Thanks. "
