I have your exact boat, 2018 Craz, and I too have the whine, but mine is at a higher rpm. Mine is around 2,500-3,000 rpm. It's the transmission gears, not the engine. My dealer says its normal. A friend has a new Malibu, and his has the same whine but at a lower rpm. I ended up installing some additional sound deadening material and that helped a lot. Costs about $100 and comes in sheets. Don't fret, there is nothing wrong. My dealer and other online comments say its the type of gears in that transmission.

I'm a little slow to respond but we finally have it resolved! Dealer swapped out my OJ prop for an ACME 2775. ALL NOISE GONE! Only noises that remain are the normal transmission gear noises like DaveM states. There was definitely something wrong with the original prop. Super high pitch harmonic noise that was super irritating. All gone now and happy to have an awesome dealer helping make sure I'm taken care of.

Thanks Raffracing, I have just had delivery of a Makai, and it's got exactly the same prop, with the same noise!

Wow! I have a 2018 Craz with the same problem. I have never heard it was a prop issue. So OJ send you another prop and did it work, or did you just use the ACME that the dealer gave you. I agree, it was annoying as hell because it was at optimum idol speed when everything was quiter. I have been happy with my OJ for wakeboarding and surfing, so I don’t want to lose performance by switching props. However, if I can make the noise go away, I will!

How does your Acme 1235 compare to the OJ 935? I saw in another thread someone recommended an ACME 2315. I guess I need to do my own research, but I don’t want to loose the performance of the “wake prop” that I paid an upgrade for when I ordered the boat. To many different numbers out there!

After putting a few dozen hours on the Acme 1235 I believe that it runs slightly smoother, quieter, and efficient than the factory "surf" upgrade OJ 935. But only slightly. After running heavily weighted, I want the pitch of the 935 back. I'm having it looked at by a prop shop this winter.
