My informal assesment is that the stock 5/8" fresh water intake line for the Universal Diesel engine stops working correctly beginning around 6 Knotts. My guess is that at some point, the sea water passing by the throughhull at a 90 degree angle begins to suck water out of the line. At this point, the temp on the engine begins to climb. Backing off to about 5.5 Knotts solves the temp problem. RPM for this "test" is about 1800+ @ 5.5 knotts and about 2000-2100 for 6. Impeller is new. Water pump is the original Obendorf.
Any thoughts?
