i have twin 1998 4.3's in my 88' carver santego. since i owned the boat the temp at cruise was around 180 degree's. i had recently replace my risers and manifolds (98 originals!) that were really clogged up. the port engine now runs at 170 degree's, but the starboard still runs at the same temp of 180. the thermostat is a 160 degree stat. i have a buddy with the same engines that runs a cruising temp of 140-150 degrees. i tested the thermostat and it works. is this the proper stat for this motor or can i dorp to a lower temp stat?
