'93 dancer prop?

[Ranchhand]

I recently purchased a 93 230 sundancer with a 305 merc. Does anyone have this or a similar combo that has found the right prop. Any advice would be appreciated.
Thanks Dave

What HP, which drive, and what drive ratio?

Oh sorry
Um 220, Alpha one and not sure. Where would I go about finding drive ratio. I'll try to remember to look tomorrow.
Thanks Dave

Port side of the drive, about 3 inches down from the top.

EFI is 1.47 and the carbed 5.0 is 1.62
(in the Alpha series)

Those may very well be the standard ratios but some boat manufacturers use optional ratios and I was trying to eliminate that possibility...

If we use the 1.62 ratio, the Merc Prop Selector shows 19" in a three blade. You may have to go to a 18" in a four blade. This is a starting point and guideline, only.

Good Luck!
