Greg Manning, Prop Hi Greg, Finally tested that prop last weekend. Sure performed nicely in the low 4000s with a heavy load. I was not able to get but 5000 rpms and 35 mph WOT with full gas/guys/gear and ice. When I dropped 65 gallons, I was at 5100/36mph. I do believe that I'd be close to 5500 if I dumped the load.
Jeff at the prop shop said the OFS option would raise the rpms but drop the mph, but where I really want to be with the Yamaha is 51-5200. I'm running 28-30mph at 4400, and it all feels good to me, so I'm going to stick with it.
Quite a bit of slip in reverse with those chopped blades and cup. Just need to pay attention to what I'm doing.
Thanks again for all your help, Greg. Performance is so much better than it was. |
