[QUOTE="turbotodd, post: 313604, member: 7376"] I had a spec sheet at one time for my old '82 OMC 15 hp. The max RPM was 7000 if memory serves me correctly. And that is assuming you have a true 15 hp motor; meaning ALL the mods were done (not just the carb). Last time I had mine in the water (about 4-5 years ago), it ran 7000 RPM from the no-wake zone to the fishing hole; about 2 miles. Then same thing all the way back. Its made that trip a bunch of times. It doesn't seem to hurt it. Good little motor; I just don't use it anymore now that I have the little 25 Yamaha. That 15 used as much gas as the 25 does (25 hp 4 stroke) and makes twice the noise; after I drown in my own exhaust smoke. [/QUOTE]
