Suzuki 3x16x21,5 modification to 20 pitch

[Manolism]

I have a suzuki 3x16x21,5 propeller that is oversized for my boat. I can’t trade it through the local distributor in Greece.
Is there a specialist that can transform my propeller into a 3x16x20 so that I can have the the same results? The 3x16x20 fits perfect on my boat with 7% slip in middle range rpm.
Is there any chance that could work ?

Normally the most you can take out is an inch but that will get you close I guess, probably within 200rpm maybe.

Stainless steel developments seem to get a decent name on the forum but if you search you will get some others I'm sure.

Buy another and either gumtree or eBay this one.

Prop specialists can usually alter pitch by about 1" up or down however 21.5 seems an odd figure for a stock prop is it a modified 21"? I'm not sure how it would work if the prop has been modified previously worth checking with a prop specialist

21.5 is a standard suzuki prop

I've had a prop re-pitched by "Steel Developments" and it wasn't a great success. The replacement I eventually bought performed much better than the re-pitched one.

The problem is the "re-pitching" is done by "bending" the blades over their length when the issue is the angle they're attached to the hub, and I have to say didn't really work. Revs dropped ok but absolutely no change in top speed. New prop, same spec, bought me another 5kn

As Jonp says..buy another, there's probably only £50 difference between getting it re-pitched and replacing it by the time you sell your own.

where abouts are you in scotland?

i have the prop you need and i was toying with getting the one you have.......

[Manolism]

I m in Greece and if the prop you have is in excellent condition we can trade them. If you agree both of us we will be charged the postage expenses.

It will be too expensive with insurance to ship it to be worthwhile for the gamble it will work for me, carry on with your sale buddy.

btw, what part of greece has scotland in it as per your tab info?

[Manolism]

You are right [emoji108].
I’m wondering how this info is in my profile 🤣.

A propeller cannot be repitched as a single figure. It can only be repitched as a variable pitch because the root (the point of attachment to the hub) will stay the same pitch no matter what bending is done to the rest of the blade. Variable pitch is not necessarily bad though.
