Polyda propeller suzuki Opinions?

As per my recent post looking for a Suzuki 9 1/4 10" pitch prop.

Ssi Marine don't have stock of their brand size 10 but could supply the 11 instead, and they think this would get me approx 5700 to 5800 rpm.

There is one ebay seller with a "polyda" brand size 10.

Does anyone know of the brand?

I realise a suzuki oem would probably be best for a true comparison but at 3 times the price, or more if going for the fancy shinny precious stainless Steel ones.

Do you think the polyda worth a punt or stick with the ssi marine11 instead?

Never heard of Polyda so can’t comment, although it does sound like one of our mod’s parents [emoji6]. Re.the stainless option, as much as I like my stainless bits & bobs, I decided against going stainless on the SIB. One of the benefits is being able to pull into shallow areas & beaches, I didn’t want to be clattering a stainless prop, or worse damage the gearbox. As far as I’m concerned, Ally props are a consumable on the SIB.

I have found with a mix of 4 props to hand on one test day there isn't always consistency between aftermarket and OE when comparing pitch sizes and predicting results. It's a bit like mail ordering Superdry gear in sizes that fit in every other brand and then being unable to get you arms in the sleeves.

For example I found a 9" aftermarket that behaved almost the same as a 10.5" that may have been OE. Also a different aftermarket that behaved just like the 9.75" OE.

However these £40ish props compared to £100ish OE are worth a punt as always a useful bargain spare even if the pitch doesn't exactly translate from OE. Also if you get the wrong one I found they re-sell on Ebay for close to the price paid.

BTW had a quick look at an aftermarket brand that has served me well, Polastorm and it seems no 10" versions anywhere.

Ok. New prop here and fitted. Now just to get the weather to try it when we get away soon

Seems well enough made, same weight, although more matt coated than the original which seems to be the norm. But of course no clue as to the exact pitch being correct etc

I did think of going oem for a more reliable comparison, and looked at the polystorm amongst others, but the 10 seems to be like hens teeth at the moment David, but will see how we get on with this one.

I get your reasoning for not going SS Pd, especially with the sites we will be landing and launching from, along with our relative lack of experience.
