115 merc 4 stroke 1775 Pro V prop selection

2004 lund 1775 Pro V SE with a 115 mercury four stroke.  This boat has an aluminum prop, which I obviously need to replace.  My research indicates 13 1/4 inch by 17 inch should do the job, but I would really like to know if anybody has a similar motor/boat setup and can give us some tips.

I like this boat so much I am considering getting rid of my FX18DV......but breaking up is hard to do.

That sounds like the right prop. A 19 is too large for that motor. My bud has the same 115 merc motor and after going down in pitch to a 17 from a 19 he has gained top end, hole shot and his rpm's are more in the ideal operating range.

I have a 75 4stroke with a 17 and it also works well with my motor. Mine is aluminum but you will get way better performance out of the stainless since there is less flex. I have run the 15 on mine and I over-rev and can't reach the desired speed with my 17 if that helps at all.

You're ringing the bell there.  I'd be on the horn to every dealership I could think of to see if someone has such a thing in stock that's maybe been there too long.  I'd also consider calling Cabela's and Bass Pro stores directly to see if maybe you can nab one from a bargain cave. 

FWIW when i was prop shopping I found that Doug's Anchor Marine in Watertown SD, and Grabingers in Jamestown both had a pretty good selection of used props and at the time were willing to let me try a used prop I thought might work while holding my CC# on file.  There may be other dealerships out there willing to do the same but those are the two I have experience with.

go to iboats.com and checkout their new prop selection, I bought two there over the years and their prices were excellent, as was the prop.

I have the same motor on a 17.5' Lund Fisherman with a 16 pitch Mercury stainless prop...works very well, tops out around 5600-5700 rpm, and is perfect for trolling cranks or dragging jigs/rigs upstream on the river. I found it was easier to find a low price on a 16 that's been lying around a shop a while rather than the more popular 17, and the 4 stroke hole shot is benefitted by the 16.

I should say that the prop's I purchased were aluminum, Cabela's was $159 retail, while the iboat prop was $98 at my doorstep!

this should help just make an account and everything and it will ask you a bunch of questions to calculate the weight of the boat going through the water

I found a 13 1/4 X 17 inch stiletto advantage new in box on ebay for $149 shipped.  So that is what I went with.   

I appreciate the help, I figured you would chime in and help me out.

Now I need a GPS and a new trolling motor...

anybody want a virtually new 55# 12 volt powerdrive?   

Corey you should have went to WC and talked with propman....  He may have another option , not all 13 1/4 x 17 stainless props will perform the same.....  You know that; but I understand your old man my not care.

I did plenty of research, and no he doesn't care.  The prop will be half dinged up and bent and so will the shaft,  after 3-4 uses!  

I am certainly jeolous of this boat.  It was professionally "winterized" and "summarized" every year, single owner, new snap on carpet, basically babied for 7 years and now my old man is going to trash it!  It's a shame! 

Permo,

Not exactly an apples to apples comparison, but I had fair on plane performance with the stock aluminum 19 pitch prop for a Yammie 115 strapped to a Lund 17.5 Fisherman.  She was a bit of a pig with hole shot though and a little on the low-end of the RPM range when loaded to the hilt.

So I went out and picked up a 17 P stainless prop by Powertech, their RED line of props.  The cupping of the stainless prop really helped with the low-end planing,  handling, and holeshot but it came at the expense of top end speed and rpms.

In general I would say you are going the right way in prop selection, but until you strap it on and give'r the onion it's a big crap shoot because not all props are created equal.

And yeah, did hear about the demise of your Alumacraft.  All I can say to that is "shiite happens and poop occurs".
