Guys, been running an OMC '17 stainless prop for some time. I dont know anything about props, first off. The boat is a 17'10" 78 Cajun Mach V with a 115 Rude, same year. It has been garage kept its entire life and my granddad bought it new. Passed it to me when he died. Anyway, I wanted to know if there was any prop I could get that would give better peformance than the 17. Currently, I can get 45 mph or so at about 5400 rpms at full trim. There is no vibration or anything, it is a smooth ride.

Also, anyone have tips to keep the motor running well other than the basics? I run 87 octane fuel with quicksilver oil, change plugs and impeller once a year. Motor has been very solid.
