2014 Möbius LSV with 330 assault. Running Acme 1433 prop. Just recently my family and I have begun to wake surf. When the stock rear and center bags are full and getting going at 10 mph I can feel a vibration and hear a growling noise coming from trans/motor area. The noise only comes when boat is heavily loaded. All wakeboarding actions nothing can be heard. I have used boat for a few days and noise has not gotten worse or better. I am going to switch to my stock 537 prop and see if noise is there still tomorrow. Any ideas before I take in to shop?
Thanks
