I have a 21 ft Cobra Viper (201D), running a Yammie OX-66 225 with a Yammie 27 M three blade stainless prop. I feel like it's over propped, in that I'm only able to get 4800-4900 rpm WOT and 64 mph. Hole shot is slow and steep, and I KNOW this boat will do 72-75 with the correct prop. My 20 ft Skeeter with a 23 Raker would do 5800rpm and 72 all day long. Wondering if anyone out there has a need for a very nice 27M Yamaha Pro Series stainless 3 blade. I'd like to do a Yamaha 25 or a Tempest 25,...but mainly,...just need to prop it down a couple notches. I'm just throwing this out there,...cuz ya never know. TIA,...hit me up here.
If ya can't explain it simply, you don't understand it well enough.
