So last weekend I bumped a sandbar and picked up some sand in the motor. Cleaned the thermostats out and ran the motor again. Started up fine and on the initial run of the morning operated great. Second spot of the day the motor would not heat up past about 80 degrees. Cleaned thermostats again and checked the poppet and cleaned the strainer.
Next trip out the motor ran great, this time I am seeing a much tighter tolerance on the coolant temps. Heats up to about 135 and cools back to about 113 or so. Settles in about 121-123 or so. Upon takeoff it runs right about 116-121 degrees on plane at all speeds. Never gets above 140 and never gets below 115 at idle. Also seeing about 1.3-1.4 pressure at idle which is slightly lower than before.
Already planning on changing the water pump but do the coolant temps sound to be in line? Motor runs great 13-15 lbs of pressure mid range and 18-22 lbs WOT.
