    Default V-Drive water depth.

    Hey everyone. We are looking at replacing our I/O Crownline on our lake w/ a Moomba however i am not super familiar with V-Drives. The one thing im concerned about is our house/lift is in a shallower spot ( 2.5-3 ft of water). So we would be idling through sand/Silt small pebbles in the area to get out of our lift. The area is not stumpy or anything. Are these drivers able to handle that regularly? We are wanting to switch to a inboard in order to surf. Thanks!

    Pretty sketchy at those depths. The prop would be damaged by stones/pebbles with any significant contact and the props are not cheap.

    Check the draft specs on the Moomba model you are considering. Border line for sure plus sand would shorten the raw water pump impeller life.

    I have my new mondo in about 2-3' of water on our lift. The bottom is silt and muck with small sticks. i don't have an issue. Before this i had a mastercraft with 27" of draft and still had no issues ever contacting the bottom. Just don't come rolling in with full ballasts and when our water is down, i move people to the front of the boat.

    I tap and glide, tap and glide tap and glide until on the lift.

    If you are getting your I/O in and out without issue I can't imagine you wouldn't be able get any inboard/Vdrive in and out even easier. Yes your prop will be slighter closer to the shoreline than with your I/O but I would venture to guess your draft will be about 1/2 as much as a Deep V hulled I/O and your I/O will hang lower in the water even with trim up.

    boated with a couple in minnesota several years ago with a tige. they had to idle for 2 or 300 yards to get out to water beyond 2-3ft deep. he just kept it at a slow idle out and back. said he never had any issues with prop or impellers.
    the sandbar we used to hang out in at green bay was pretty shallow from 1/4mile in. had to run it pretty slow when coming up as you could see the bottom then deep, then shallow again. I hit bottom a couple times while backing in to park. it was all sand so never an issue.

    2-3ft wouldn't bother me after the first time or 2 getting comfortable with the path to take to deeper water.


    bigger question for you would be depth of the lake. if less than 15ft surfing will not be ideal. we noticed a huge difference in the wave when we slipped out of the channel on the fox river. going from 20ft to 12-13ft made the wave crap almost instantly.

    What kind of lift do you have? I just purchased a floe vsd 6500 for my mondo. Wondering what the clearance is between the bottom and where the v drive comes in to avoid the cross member. Basically, I have a shallow slip and am worried about how much clearance I need for the lift beyond the 27 inches required by the mondo. Thx.
