17.8 prop suggestions

Ross R · 09-16-2008, 05:50 AM

Just curious what everyone was using on their 17.8s with the merc 60 2 stokes. My buddy in Islamorada recommended the powertech 4 blade with a 13" pitch. I am ready to pull the trigger on a new one and I wanted to see what other options were around.

want a used one

I've got a 4stroke and it takes a 11p to make it turn 6000rpms. I'd say 13 would be just about right

I'm running a 3 blade stainless vengeance (merc) on my 60 2 stroke in a 15 pitch. This runs the motor about 5400rpm - on a merc analog guage - accuracy? The hole shot is average, but I get over 41mph alone and 38mph with 2 guys and gear in an 18 waterman center console - GPS. I have thought about dropping to a 13p 4 blade for hole shot, but why fix if it aint broke? Plus I like the look on other guys faces when I keep up with or pass them with their 90hp an mine weighs about 100lbs less.

I run the same 15 pitch on mine as well. It's what Hell's Bay recommends.

I have a 90hp merc, I run a 14p. I am ready for a new prop though and I think I am going to go with the 15p. All the 17.8's I have been in with merc 60's all had 15p props on them and ran very nice.

LOL me too. I love doing that to guys with 115's.

A 13 pitch, 4 blade trophy for the 60 2 stroke Merc on my Waterman18

I would think a 17.8 w/ a 90 merc would turn something like a 21 or 23 or as big as you could get for a 3 cylinder 90. My Silver King turns a 4 blade 19 Turbo @ 5700 trimmed out. That boat likely weighs close to double the HB. Seems like a a 14 or 15 would wind out a lot.

I am winding out now because my prop is basically done for, but with a new prop I run at about 5500-5700.

I never though about going with a bigger prop. I love the wholeshot/top end combo I get out of the 14. I know a guy who run a prop shop and would let me take a couple to try. I may do this as I need a new prop anyway just to see what I could get with a higher pitch prop.
