Just as a high performance or racing engine is
built to more exacting specifications than a production engine, Mercury
legendary prop lab is available to modify production and racing propellers for
optimum performance. Using the experience gained from years of testing at Lake X
and race courses around the world , the prop lab will blueprint and balance a stock
propeller to get the last few miles an hour out of your boat. RPM adjustments of
up to 200 RPM are possible.
Speed increases of 2-3 miles per hour are common.
In many cases, this is the biggest gain for the least money you can make.
Cost is about $150 per blade.
