I assume you are talking about the 68" that "slowride" AKA Big John has listed....that prop was mine and on a very healthy s/v 540 and worked great.....the advantage to the shorter prop is the increased snap that you have. It will work just fine on that 520 and do everything you want.

Is the degree in pitch still the same as when u had it on your s/v 540? What degree pitch did you have in it? What was the rpm you were spinning it at? What kind of hull were you running it on? How's the blade shape do you know? Thanks for the information

I am fairly certain it had 9 degrees in it and I could spin it 2950 no problem. I had it on a 12' full deck Thurman, pretty heavy boat with stainless rigging. It performed very well on that boat and would run anywhere you pointed it. The blades are perfect, no dings or anything

I called him and he already sold it but there is another one I'm looking at. Just wanted to make sure it wouldn't be to short for my 520. I talked to a couple buddy's and they said it would be fine. I have a 11'x7'6" war daddy and the three blade seems to be to much prop for it. What was the cruise rpm ?

I have a 11x7 true Thurman with stainless bottom and a e185-0520 CONT, had a 68'' 6 blade warp at 8 degrees tuning 2850,. cruise rpm was 1500rpm at 25mph. Then went to 72'' blades set at 6 degrees turning 2800, cruise is now 1300rpm at 25mph with better low end push on the hill, with a little slower snap.LSX1

My cruise was around 1550 and somewhere around 28mph, top end was in the low 80s. I can assure you that it wont be to short, you will love it on that deck over. With that being said the longer the prop will always lower your cruise RPM some as LSX1 has mentioned....72" prop has terrible snap, I personally would never own a 72" on the type of boat you have....I have owned thurmans, davis's, war daddy's, and more chuck hawk steps than I can count, and every one of those boats I had either a 68" or 70" max.
