I am currently putting together a stumpknocker 14 / mercury 25 combo...I'm looking for a good starting place for prop pitch for a 89 mercury. Haven't had a lot of experience with smaller tillers and no tach to use for rpms...Setup now with a manual jackplate 5" setback, 3" rise. Any suggestions would be appreciated. Thanks

A Tiny Tach is really cheap and easy to install. Costs less than any prop so it will save you money in the long run.

Start with a Mercury Vengeance 13 pitch. It should match up perfectly with your rig.

13 pitch is a great all around size on the 25 merc.  I have a cheapo Solas stainless 13p on my Merc 25, and it's on an IPB 14/Skimmer skiff.  Running a fixed jp with no issues.  Good prop for the buck.

13 may be ok on a Gheenoe but a Stumpknocker is A LOT heavier I would go with a 12 at most

Thanks for the input...i'll start with the 13 and work from there..

Thanks for the input...i'll start with the 13 and work from there..

I have an aluminum 13p I ordered from mercury. I used it once and put it back in the box. I'd let it go for some bucks, pm me if interested. Otherwise I'll just keep it as a spare.

I appreciate the info...i put a 4 blade 13 pitch on it and it does well. Don't have a tach but runs fast enough and handles well for where I go...again thanks for the offers to use the props.

what kind of prop? Brand? Stainless?

Anyone running a 4 blade on their merc 25 that care to share data or specs on the prop?

I ran a cupped stainless 13 pitch Powertech on a 25 merc on a Gheenoe Classic
