I have a 1985 Carver 3207 Aft Cabin. I hit something floating beneath the surface in deep water, and despite prop tuning, I still have some vibration from the starboard prop. Prop shop says it should be replaced.

I am looking at getting new Michigan Propeller DQX 4 blades to replace the original Dynaquads. Michigan Propeller needs to know the following information to help with selection.

1. Gear Ratio
2. Max Rated RPM for engines
3. Wide Open Throttle RPM
4. Wide Open Throttle hull speed

Can any fellow owners please help me with these specs? I know that the gear ratio at least is stamped on the transmission, but I am away from the boat at the moment. That said, any help at least on the other specs would be greatly appreciated.

Also, if anyone has experience repropping their older boats with DQX propellers, I would be grateful to hear from you. There are so many options (cupping for example) that it is bewildering.

Kind Regards,
John
