to be 100% "safe".......0 rpm's :rolleyes:. The best mix of speed and effeciency would be 3,200-3,300 in most boats.

3250 should provide the best economy, "keeping you out of the 4 barrels" as my brother in law would say. (if equipped). My throttles have a notch that keeps them RIGHT at 3225-3250, according to my tachs anyway.
