I have a 209 Escape w/ F225. I just did total refit to boat and shed a fair amount of old wiring, weight ect. and I am going to reprop. Does anyone have a feel for the difference in WOT RPM"s beteen the Mirage Plus 15 1/4 x 19 versus Yamaha SSII 15 1/4 x 19??? I figure that I will loose some RPM's going to the Mirage Plus but I would like to get a feel for how many. I would like to turn at the upper end of the RPM range and don't want to risk lugging the engine with the Mirage Plus 19. Thanks.
