"Okay, so I just myself a shin
"Okay, so I just myself a shiny new motor that is rated at or about 300HP. I am using a 280 outdrive. I removed the prop that came with the boat, which was a 15x15. I need a starting point here for a new prop. I have looked at various prop calculators, and they all seem to be inconsistent with their results. My boat is a 1988 Marathon, weighing about 4500 - 4800lbs. The gear ratio of the outdrive is 1.61:1. Can anyone help me out please?"
