525SC Overheating at Idle
I have a ’97 Fountain 42 with three 525SCs. It has been parked and not run for two years. When I started one of the engines on a hose, after about ten minutes the temp gauge went up to 140 then dropped back down to below 100 and the overheat alarm started going off. I have replaced both the thermostat and sea water pump. Water pressure is normal (compared to the other two engines) while running. I also installed a gauge where the alarm sender is located in the intake manifold and verified the temp is around 190 there and the water is in fact cold around the thermostat. I am not sure where to look now.

I’m plumbing a twin-engine power steering with pressure from both pumps. I have a return line question. If I run a single line thru the straight part of a tee to a second cooler then branch from tee to first cooler, will it show preference or overload second reservoir? Or should I turn the tee and branch and run 2 sort of equal length lines to coolers to better balance the flow? Or, should I run sealed reservoir caps with hose reservoir cap to reservoir cap to balance? I am wondering if a closed system will present problems. My experience is with Sea Star style hydraulic steering which is fairly basic. My new boat requires new knowledge.
Thanks for any info you may have.
