I have a 1989 Sea Ray with a 350/260hp Mercruiser w/ Alpha One outdrive. Is there any reason that I shouldn't run it without a thermostat?
I'm having overtemp problems at idle - especially after running down the lake on plane for a few minutes, then dropping to an idle - temp quickly climbs to 220*F - which I know is way hot. Hopefully, I haven't done any permanent damage to the block or heads.
I'm going to replace the impeller/pump housing in the lower unit and see what effect that has. Current impeller is about to start its third year.
I'm also hoping not to have to mess with risers. Is there a good way to check them for blockage without removing them?
