Dear Mark,

"My client recently purchased a 1990 44' Viking Motor Yacht.

During sea trial our Max. RPM was 2350 (It Should have been 2500).

Later we learned that the previous owner, working with a well known prop shop in conjunction with the factory, had four different sets of props on the boat and this was the best they had accomplished.

We took the props to Precision Prop Technology, Inc. gave them the spec's on the boat and told them to take their best shot with Prop Scan.

The boat now reaches 2500 RPM and gained 2.5 knots of speed. "Enough said!"
