OJ 945 15x13 question

[LAwake]

I bought my Helix a little over a month ago and have been slowing trying to dial in the wave. I want to make sure the prop I have is what I need and will handle the weight I'm adding to my boat. When I got the boat it came with an "upgraded" prop, the OJ 945 15x13. I've taken the stock 650 rears out and added 1140s. I have the Surf Edition so I have the hard tank (I guess it's 400 pounds) and the IBS bag (which I guess is 400 as well?) I ordered a bunch of lead today from LEADwake. I plan to put bags in the side compartments both surf and non-surf sides as well as up in the bow.

I just want to make sure the OJ 945 will handle the weight of all the ballast upgrades I'm doing.

Yep, that’s the prop I upgraded too, so you are good to go.

Awesome, thanks Stazi. I didn't realize you had that prop.

When I bought the boat it had the 14.5 x 14.25 prop, so I ended up changing that pretty quickly after we started loading up the boat with a ton of weight and it was struggling to get out of the hole.

It does sacrifice top speed but I couldn’t care less. This is a tow boat, not a race boat.

I'm going to be trying the Acme equivalent, the 2773 (15x13) later this week. Glad to hear you're happy with it. I replaced the 1235 with a 2419 (15x12, .075 cup) last week but I think it's a bit too aggressive.

The 15x12 with cupping will be basically the same as. 15x13, without it, IMO

The 15x12 has less cup. .075 vs .105 for the 15x13

What is your opinion of the 1235?

I run the 1235 on my Mojo, at least 3500 pounds for wakeboarding, 4200 surf, does a fine job. I just picked up a 945, going to see how it performs soon.

It's okay overall, but really struggled with 3500 lbs ballast, 5 people, and the ghetto gate I made to test out a possible wake gate system.
