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