SC 18 repower

[76Red18]

I have an 18 with a 99 150 Johnson, T-top and loaded pretty heavy. A 15x17 Viper stainless gives me a great holeshot,25-27 mph at 3700rpm,40-42mph at 5500 rpm wot. 2.5 mpg at 3700rpm is the best the PIG Johnson will give me(low weight and bullet proof motor though). I had a Michigan apollo 15 3/4x19 on it for a while but wasn't happy with the holeshot. Top speed was the same with wot at 5300rpm. Too much prop for the way i run my boat. Lots of praises about the Mirage Plus on this site, would like to try one myself. If you run your boat heavy, a 15 pitch could be too much, but thats what I would try first. Some marinas do have test props by the way.
