    Default Couldn't keep thru-hull from turning

    I've been working on my ballast install today and I'm almost done but ran into a problem when tightening the thru hull nut. I had a buddy stick a prybar into the hole from the bottom to try and keep it from turning but you can't get any leverage. Anyways it's pulled flush with the hull and I used the marine sealant on the top and bottom, and there is no play in the fitting. Think I'm alright? Thanks

    If it has the little tabs or bars on the inside of the fitting you may be able to use this trick.

    Put a wrench on the flat edge of the handle for more leverage. I used this breaker bar handle on both my bottom (underwater) thru hull and above water thru hulls on the sides.



    It's not a high pressure system so as long as you have some sealant under the fitting you are probably good. For a below the water connection I would definitely spend a little extra effort to get it as tight as possible though.
    Old enough to know better, young enough to do it anyway.

    Z,

    What you are experience is not uncommon. The marine adhesive makes for a great lubricant while in its uncured state. So even with the jam nut tight, the thin barrier of sealant can allow the t-hull to rotate. let it cure and you should be fine. Also, I would go ahead and put on the ball-valve while you are at the point you are at. This way, if you need to rotate the whole setup to get the ball-valve handle oriented so it has the clearance to be shut off, you can rotate the assembly.

    Don't want to over tighten, crack the gel coat/spider cracks... The sealant is what makes it water tight...

    Agreed. A whales sphincter does not spin and isnt cracked.

    And if anyone wants to see a whale weiner i got a picture

    Haha, no thanks. I let the sealant dry good before I put on the ball valve and kept an eye on the nut to make sure it wasn't turning as I tightened the valve. It held tight so I think it's good to go. I'll check it on the water before I back off the trailer. Thanks for all the help guys, I couldn't have done this project without all the good people and threads on this board! I can't wait to get on the lake sunday and try it out, throwing pumps over the side of the boat is for the birds

    It's also for folks with boats that have hard tanks and need more weight but don't want to drill holes, add pumps, etc.
