Generally, it has been my experience that a Whaler Drive 25 will outperform the notched transom model, for two reasons. It rides a lot better because of the extra hull length in the water, and carries an additional 150HP rating. This more than makes up for the decrease in speed from the additional wetted length of the 25 WD. On a 25 WD, I would not recommend less than twin 200's.At 4000 RPM, and running 21" props on twin Mercury 200 EFI's, which I use when the boat is heavily loaded, I'm running about 41 mph and close to 2.0 mpg. With the 23" pitch props, used for lighter loading, speeds are even higher. With these, 3000 RPM gives about 32 mph cruising speed, engines quietly loafing along. |
