Sorry Ian forgot,
Alloy prop's are usually a larger diameter than the same size Stainless prop so you can raise the engine a little without getting slip prob's so you have less drag in the water thus giving you better top end.....worked for me

Am I likely to see any advantage with a stainless prop on a 70 hp engine , other than the fact thats its more robust .
Ian,

How "very good price" is it?

If cheap enough to not matter then why not just buy it and try it?

Last two secondhand ( but good condition) SS Laser II props that I have bought cost 120 and 140.

My experience is that you can run a slightly higher pitch stainless prop than an alloy one.

Regarding killing your gearbox / shaft if you hit something, whilst a stainless prop is likely to cause more damage this still should be covered by your insurance. Might be a little inconvenient though if you do. Are you likely to hit something? - Some people are more "lucky" or are better at making their own luck than others!

BTW - have had stainless props on my last two boats with no problems.

Regards

Duncan

Where do you get a good 2nd hand prop? I would like to have another SS one for a Merc Opti 150. Anyone have one?

Its 180 , cheap for a stainless prop , but not cheap enough just experiment with .
I shall go with the argument that a stainless prop is thinner and sharper hence more efficient . So Iam hoping the slight gain i want on the performance of the 19" alloy iam running will be found with this prop .
Fingers crossed or ebay here it comes .

didn't buy it , spoke to dealer told him what I had revs speed etc , he told me same as Spike , to go down a pitch when changing from alloy to stainless . So for same performance as my 19 I need a 17 in stainless .
I give up stickingwith alloy , and they are only 99

That's not too cheap - I'd recommend you shop around a bit more. If you really want stainless, you'll get one for less than that.
