Took the boat for the first time to check out the new exhaust manifold and carb rebuild for performance and leaks. All went well with temp maintaining at 140-150 and no leaks but the oil pressure when other than idle stayed steady at 60 and idle speed 40-50. Can't find it in the manual but is 60 the norm for WOT and steady high speeds? Engine Serial 0F003200 and drive is oD882510 on a 1993 SeaRay 180.
