In the premiere issue of a new publication called Bass & Walleye Boats, a question was asked in their “Shop Talk” section about the use of synthetics in outboard motors. Here is the editor’s response:

When I was actively campaigning an outboard race boat in American Power Boat Association closed- course racing, I did some extensive testing with both synthetic engine oil and gear case lube. These tests were conducted under controlled conditions, both in a test tank and on the race course. The engine oil was worth roughly 100-150 rpm on top end, which translated to about 1 mph. The gear lube added another 100 rpm and gear wear was retarded greatly after several races with the synthetic.

Both products were made by AMSOIL of Superior, Wisconsin. I cannot substantiate horsepower or fuel efficiency gains with actual dyno-generated numbers, but the results on the tach and speedometer, coupled with the reduced long-term wear, make synthetics a good investment for the boater interested in that “extra edge. ”


On March 29, 1994, AMSOIL received a patent for the Dual Remote Oil Filtration System. After an approval
process of nearly two years, AMSOIL dealers can now claim exclusive rights to market this unique filtration
