prop stainless vs alloy

A local chandler has a stainless prop , genuine suzuki to fit my engine at a very good price .
Am I likely to see any advantage with a stainless prop on a 70 hp engine , other than the fact thats its more robust .

Does that work against the gearbox if you hit something

If I were you, I would only buy this prop if it is a fully verified 18" pitch

Have you ever dinged your ally prop? If you have I'd agree with Bedajim.A gearbox is a lot more money than a prop.

props

Hi guys,

I run a 11m rib with twin 250hp outboards in cardiff we take people out for fast rib rides.... On sunday i was on my way back to the marina and i struck an object floating just under the water i did not think it was that bad untill i lifted the boat out this morning and found that i had bent my stainless prop which in turn bent the prop shaft!!!!!!. Stainless props are not forgiving please stick with your ali prop it will save you a lot of money i am looking to get some made up for my boat ....

Ryan ...

Remember it may officially be summer but the rivers still look like they do in winter - they are carrying a LOT of tree trunks and logs out to sea. Just cos the sun has come out doesn't mean the logs have gone!!!

Shame about your engine. I also wonder about the so called advantages of stainless props - maybe it's because they are nice and shiny???

But then if you'd of hit that submerged object with an Ali prop it might of damaged the propeller so much it wouldn't of got you home had you been a single engined boat.
