What prop should I buy for a Craz?

[That Guy]

Looking to buy a spare prop for the Craz to take advantage of BF sales and to either have a backup or possibly swap one out for better performance.

Boat has the standard OJ 14.25x14.5 which appears to be the same as an ACME 1235? and I ordered the max surf package which is factory 900's in the rear so total ballast standard is 2800lbs.

Obviously I've yet to dial this in but in my previous boats we've needed to add additional ballast, usually in the bow to lengthen the wave. We usually surf with 2-4 people in the boat so I've got lead weight bags to hide under seats etc if needed.

Any input on prop choice or ballast setup is appreciated. I see on some threads people are running 3500-4500 in ballast....Will the standard prop push that fine?

I did the oj 945 on mojo and am happy with it. Could be something better out there though? I do not think that it changed a single thing to surf wave. However, I noticed a lot when full crew and wakeboarding.

945 is as good as it gets. It's 15 inch and it's the largest most agressive prop you can fit on the craz. Acme 2315 is the equivalent, but the 945 is the factory option, so just choose that option from factory. I run 4200 lbs ballast in my craz and the 945 gets the job done.

How is your 4,200 setup?

Appreciate the input. I noticed the OJ945 was the optional prop on the build site but didn't see it listed as a suggestion on wakemakers site.

I opted for the standard prop on the build as the dealer recommended it and also since it was $220 upcharge, which is nearly half of the cost of buying one anyways so why not just buy one after the fact and have 2 different props, either to swap out and test back to back or to have a spare in case one gets dinged up.

With the black friday deals the OJ945 is under $500 shipped, so I think I'll go that route.

Now what about a removal tool? Harmonic puller or C-clamp puller? Figured I'll buy everything with it on sale.

1100's in the rear. 600 in in front of back seat on floor and 300 under bow filler. Plus bow sack and in floor tank. Will be swapping out the 600 for two 400's under bench seats in front of 1100's before summer. Plus steel shot under bow filer instead of sac.

Damn! Did you increase it incrementally to get to that point or just threw everything you had plus the kitchen sink and said to hell with it?! LOL. Just wondering if there were any diminishing returns you noticed.

[mattsask]

There is a point of diminishing returns, but I'm walking it. I didnt even bother filling the stock 650's, i swapped to 1100's before it hit the water. It's the perfect ballast setup with a crew of 6 or less. The 1100's are a huge improvement over stock bags (I only know this because I've looked at the wave with rear bags half full). And the extra 600 in the back takes the wave to a whole new level. I put 96 hrs on my craz this year, and I'd say about 90 of those were surfing. There was a lot of experimenting, so feel free to pick my brain on all that kind of stuff when you get your boat.

The C clamp puller is very easy to use but watch videos how to do it correctly or you could break your puller.
If I was to go with a prop I would go ACME 2315 since we are at high elevation and don't care about top speed at all.

[PuraVida]

I run 4200 ballast in a mojo and originally got the 15x13 from the factory. I later bought a 14.5x12 and didn't see much difference. Wish I would have gotten the 15x12. She still struggles to get on plan with full ballast and more than 8-10 ppl. There is a definite tipping point, if I empty ballast for a couple mins its gets on plan just fine.

Appreciate all the responses. I'm like 600-800' ft elevation so not really an issue there. I opted for the OJ945 simply because it was the factory upgrade option and also about $75 cheaper than the next one that appears to be basically the same. I also got the quick change kit/etc and may swap it out at some point this summer but will sleep better knowing I've got a backup prop should anything happen. Can't wait to get some time behind the boat come spring. I did find out that it's 3000lbs factory ballast with the Maxsurf package I ordered, and I have an old 750lb fly high with a tsunami pump to play around with if needed, but hoping it's great out of the box.

Get to know the process of changing the prop and remember the nut has a torque rating and not just jam it down. Nice having a spare prop but knowing how to easily/correctly change it is different.

Did they add bigger bags for 2017? If I remember it was 650's in the rear, 500 hard tank, 500 IBS = 2300. Where did they add the 700 pounds?

The hard tank was 700 in 2016. Will be interesting to see what's in the 17's

I heard factory option of 900s in the rears now also for 17.

Good idea. I'll give it a go on the trailer just to make sure since it'll live on a lift all summer.

And yes, as noted above the hard tank is 700lbs and this year they added the MaxSurf package which gives you 900's in the rear for a total of 3000lbs.

A thought I've had after reading where people upgrade the 500 ibs to 750 was to do that first if I needed more bow weight, but at 3k standard it's more weight than I typically ran in my last boat and had a great setup.

My Craz had the 500 IBS and it filled the whole bow plus some... Not sure how anybody's getting 750 under there???

I'd agree with that. I don't see how a larger sac could fit, that's why I've been hiding ballast under the bow filler cushion.

Fair enough, I have no clue as I've only crawled around on the boat a couple times in the showroom. I have lead wake bags I can put around the boat if needed, but hoping not.

Get the bow filler cushion and put 300-400 of your lead under there. It's a perfect incognito spot and should stretch your wave out a bit

This setup seems primarily for a surfing. Do you run similar weighting for wakeboarding? My current set up is the plug and play 900's in the back, center tank and 650? that wraps in the nose under the seats. The rear storage compartments are definitely large enough to accommodate a bag that size (900), but it doesn't appear to be much more room to account for the potential additional surface area of an 200 lbs. Are your 1100's custom sacs designed for that compartment?
Ultimately, I'd like to have a little taller wake at 70' and adding weight to the tail would accomplish that. But it makes me wonder if it would be an exercise in futility given the limitation of the compartment with a bag that size.

[mattsask]

Ya that's a strictly surfing setup. The 1100's definitely don't fill 100%. For wakeboarding I run bow and center full, rears 60-70%. I'm coming from riding a dd mastercraft, so this wake is a lot steeper. I might try filling rears totally full next season, but as of now the wake is plenty steep for me. If you want more weight in the back, there is room behind those rear panels for a couple lead wake bags. The ballast pumps are mounted about half way up, so you could probably sneak 100 lbs on either side.

What about draining your bow a little bit, you're running almost 3000 pounds binding riding!

I would definitely give it a shot, you won't be disappointed. Although going completely full in the nose will flatten out their true potential, and make them wider.


I may give it a shot. Thanks for the advice.

[MMPRES]

It's a little temperamental. If I take any amount out of the nose, it takes FOREVER to plane off, if it does at all. I may just get an additional bag to throw in the center to sit the whole boat deeper.

Love all the ballast I have a 16 Craz with standard 2500 lbs if I change out the rears for the 1100s will I need to do anything to the bow bag also by making the surf taller what are the pros and cons. Thanks mike

You won't be able to fit a larger bag in the bow than came stock. I run 250-300 lbs under the bow filler cushion to balance out the 1100's. You will need a couple panel savers kits from wakemakers if you upgrade to 1100's. Otherwise the panels will bow and touch your plug wires. They are cheap though $30 per kit.

I looked on wake makers are they actually 1140 lb bags

[Catman]

What position do you keep the wake plate in . Also do you fill both rear bags full?

It depends how you prefer your wave.

Reviving this as I just took delivery of my craz. How does the wakeplate effect the wave when wakeboarding? I am still in my break in hours and want to know as much as I can to get out there and ride.

Up makes the wake steeper, down mellows it out a bit.
