Hi
I have a 1980 c&c 32. It had a plastic/composite prop on it when I bought it. It had a slight chip in it on one of the blades ( two blade prop). Boat ran great with it. No vibration so I left it. But I hear about the indigo prop and how it is designed specifically for the A4. And was sick of other sailors pointing out my chip when the boat was on the hard for the winter.
So I ordered the Indigo prop and put it on with little trouble. Found the old plastic prop was barely on the shaft. Pulled it off with my hand. So glad I changed it.
Once back in the water i had to re-learn the new prop to gauge the rpm, boat speed and reversing characteristics. Seems it need way more revs and vibrates way more. Causing cups to shake in the cockpit cup holder. And once I drop to neutral the revs are way too high and have to throttle way down to idle in neutral. And at low RPM I can hear a slight resonance squeak.
Is this normal for these 3 blade props?
