OJ 945 15x13 question

[mcjimmy33]

I have a 2313 in my crazy (15x12 with .150 cup) and its a beast for surfing and I can hit 38mph without ballast. Pretty solid setup.

That's good to hear. I've tried the 2419 (15x12, .075 cup), it is a surf beast but winds out pretty good at top end. Then 2773 (15x13, .105 cup). It would only get to surf speed (11.5) with the wake plate all the way down. Better at the top end, but that didn't matter. Prop shop is gonna swap that one out for the 2313.

What elevation were you running the 2773? Also, what boat and ballast? I only ask because I think I might switch from the OJ 945 to the 2773 for lakes between 3600ft and 5000ft.

2200'. I ended up going with the first one, the 2419. Great prop.

I have a 2018 Craz with the “upgraded wake prop”....however, I had a high pitched whine in the boat the first year and could not figure out what the problem was until I researched it on here. It ended up being prop whine. I had never heard of such a thing, but I showed the dealer the thread and they replaced the prop for me with no questions asked. I was told OJ had a run of props that were out of spec. Don’t know if that is true or not. I thought I had an OJ 945, but I just checked it tonight because I am thinking getting a spare, and it is the OJ 950. Both are 15x13 props, but the 950 has a cup of .130 vs. the 945 with a cup of .120. What would I gain or lose with the cup of .130 on the 950. In my opinion, the 950 performs great. I have never had issues planing out and I can hit 38mph. I am thinking I would just stick with the 950.

Shoebox - I started with 3337 and felt it was struggling with weight for surfing and a loud whining. I talked with JT at Nettles (great guy) and he recommended 3145. I like it a lot better for surfing with weight.

So I assume you liked the 2419 better than the 2313? I am considering the 2313. I run about 3,300lbs of ballast and 4-6 people in the boat plus gear. The OJ 950 I have is fine for surfing, but can struggle to get the boat on plane if I wakeboard at 100% ballast. I can currently hit about 38mph on top end.

I honestly don't remember if I even ended up trying the 2313. I really did like the 2419. Did the job well. I had about 4k total ballast in it, plus however many people, usually 3-7.

Ok. If I understand it correctly, the 2419 has the same specs and the 2313, except the cup. The cup on the 2419 is .075 and the 2313 is .150. So I believe the 2419 would provide a little more top and the 2313 would have a little more low end.
