Johnson 88 SPL prop size?

[slapshotjh]

I have a 1989 Johnson 88 SPL. I purchased it used with an 18 foot Sea Pro center console. The boat is light, it has no options other than the console, no fuel tank other than 2 6 gallon portables. <br /><br />What propeller should I use for better fuel consumption and better top end. The prop on there now is stamped 13X19. I believe it was used for skiing. I don't have an owners manual to tell me what WOT should be.<br /><br />Right now 4000 rpm gets me about 26mph. the boat seems to top out at 31 mph at 4800-5000 rpm. Is this the correct set up, or should I expect more?<br /><br />Thanks,<br /><br />Jon
