3 or 4 blade for skiing?

[moomba wannabe]

Ive not seen this answered directly so I will simply ask it; is there much of a difference in the wake from a 3 vs. 4 blade prop on a direct drive? I have an 05 Outback that came with a 4 blade and I mainly ski. The wake is pretty nice but Ive skiied behind other DD's with better (smaller) wakes so I'm wondering if its worth it for me to change to a 3 blade.

I have a three blade on mine for skiing.I've never had a four but i've heard others mention more bump at 22 using the fourblade.Four blade is/was the wakeboard upgrade prop when i purchased my boat . I ski so i stuck with 3 blade and no issues.

moomba wannabe - Interesting. I ski, so bought an Outback ('07) that came from the factory with a 3 blade prop, which was the set up used to certify the '07 Outback for three=event towing. Wonder why yours has a 4-blade prop? - Deerfield

Prop is not going to change your wake, at least not any measurable amount. it's just a tradeoff between hole shot and top speed. people who weight there boat a lot tend to prefer the 4 blade as it will get out of the hole quicker and probably will allow them to control speed a little better.

Actually, the 4 bladed prop will slightly alter the table and wash that your wake makes at slalom speeds. I had a MC with a 4 blade and loved it. Tried a 3 blade on it and noticed a slight difference crossing the wake.
I have not tried a 4 blade on the Moomba, but I would like to see the difference. For sure, each hull will react differently to props, so you can't say just because this MC (CC or Bu) reacts like this, then the Outback will also.

Someone buy both and run a test, please.

I should clarify - It came new to me last summer with the 4 blade, so could have been any number of reasons-original purchaser upgraded to the 4 blade or replaced the original with a 4 blade. I obviously would be very interested in a test myself but if noone has or does one and I end up with a 3 blade I will definetely share my comparison. I do have alot of other improvements towards the front of the line so may be awhile.

My dealer said when I pick my boat up in april he would put whatever prop i wanted on it and he would just put the one he takes off back into there stock. was told by oj to go with a 14 by 14 four blade for top end as I enjoy barefooting and my new boat is a mob ls
