Prop help for a 1985 170 with a 115 hp Johnson
« on: July 01, 2014, 09:37:25 AM »
I have a 1985 Osprey 170 with an old 1985 Mercury 90 that I am ready to re-power.  I am installing a 1998 Johnson 115hp.  I am wondering what the prop should be?  Any thoughts?

What size were you running on the 90?  I'd say you can go up an inch or so in pitch with the 115.
