Vibration while surfing

[sledneck__11]

13 moomba mobius 900 pound fat sac and ibs, while surfing we got a vibration in the hull prob from cavitaion from the list of the boat. Has any one else had this issue or ways to solve this or just the nature of the beast? Also while people have ballast full and 10 people on the boat hows everyones heat gauge running? Thanks again everyone

Have you inspected your prop?
What prop are you running?

Check your drive shaft coupler bolts too.

the prop is the original to the 13 lsv that i now of, 1235 and prop looks great not knicks or anything. It usually only makes the noise at low speeds but it is a weird one to explain how it sounds.

If urea an OJ (stamped on the prop) low speed growing, vibration feeling is normal. If your getting a lot of cavitation, (feels like boat is slipping in the water) then you might need a new prop. My LSV at 2200 ballast ahs 5 people required an upgrade

The 1235 should be plenty of prop. I would remove and reinstall my prop before my next trip out to make sure that it's seated well.

Do you feel it in the steering wheel, i.e., is the wheel shaking? Could be the way the prop wash is hitting the rudder. Changing the weight a little might change it a little bit.

Nope steering wheel has no vibration it just more of a groan at low speed when boat had 10 people, 900 rear locker 400 center 550 ibs i had never had it this full before with the new ballast upgrades

I just bought a '13 LSV it has a vibration feel at low speed. It was thoroughly checked by the mechanic and everything was fine. Come down to cavitation or prop wash. Have put 40 hours of surfing on the boat since it was purchased with no issues. Surf on!

Do you have the flow surf on yours or how are u weighting your boat? Wakeplate and speed? Any pics always like seeing other lsv's wakes
