prop for channel islands 22?

[Murv]

Bit of a long shot this, but does anybody know the prop size for the above with a 140hp mermaid engine?
My boat is on the hard at the moment after being delivered, it's being launched Saturday but the prop really needs changing.
Annoyingly, the size has disappeared from the hub so can't get it from that.
Not a major problem, I can get the boat out at a later date and get the prop off to find out what size it is and find a replacement, but obviously handy if I could order something up to be delivered before Saturday.

I got a new prop for mine this year from Clements it's a 14x 13.5 3 bladed hyperform.
However I have asked the same question about prop size as I'm pretty sure I'm under propped at present as hitting 2700rpm and only doing 14 kts.

Gat a recommendation from your prop supplier such as Sillette, Clements (and others) based on your boat's data. They will have a calculator to work it out. Then if it is horribly wrong (unlikely) you have some comeback.

I had one and changed the prop but can't find the dimensions. However a good friend did the same a few years ago, he fitted a 4 blader which certainly improved performance. I'll ask him tomorrow, as a naval architect I know he did some in depth calculations. I'll let you know when I have spoken with him..

Excellent, many thanks all

Sorry Murv, he's looked but can't find the details.

No problem, thanks very much for asking though, it's much appreciated
