    Running at that RPM for extended times should not be an issue as long as the engine is able to operate within the designated RPM range at wide open throttle.

    Quick question: I have a 2008 Moomba LSV with the 325 assault MPI (top spark arrestor) with the factory OJ "wakeboard" prop I was turning 5200-5500 at WOT and the rev limiter never once kicked in. Wouldn't this suggest the 5200 - 5500 RPMs is with the engines specified RPM range? No engine modifications or tunning have ever been done to the engine. Thanks.

    I forgot to add; I have since swapped props to the acme 1847: No Ballast, WOT I'm at 4600 RPMs / 38 mph (gps). Fully loaded with 1900#'s of ballast I'm at 3000 RPMs wake surfing @ 11-11.5 mph. The only time I've run WOT is to test the old prop and the new prop. I'd be interested to see where the new prop lands full ballast WOT. But can't imagine repropping again for scenario I would never put my engine through?

    How will propping the boat for full ballast, WOT RPM impact the RPM range at wakes surfing speeds?

    Thanks again for your help!!

    This is what I'm wondering. You say to load the boat up with all the people and ballast I'd ever do and then test WOT. The only times I've ever gone and ever will go WOT is with empty ballast. And I've never seen my engine get even remotely close to hot. Our water temps rarely get over the low 70's so that's often a 20+ degree decrease from what our friends in the South see.

    Also, it'd be a little tricky to fill EVERYTHING and then try WOT, because I have probably 650 pounds of ballast that's exclusive to the Port side and not the starboard. I suppose I could compensate by having more people Starboard if I was to test. But I'd be ill advised to try to go WOT in a unevenly weighted boat.

    never had the need to drop the hammer when full surf ballast was full, that 345 "Surf" motor with the 1235 prop was a wicked package. Just roll the throttle on and everyone would be right up.

    Oh I don't have to, I just love coming out of the water like a raped ape.
