Thank you Olivier

I will follow your instruction and complete next haul out, it was only leaking some when under way, the plastic nut is almost all the way down so I guess it’s due

Kind regards Paul - Fortuna II 55/17

Hello Paul,

no it's not OK to replace the packing material while the boat is afloat. You would then have a strong water ingress while you're working for installing the new stuff.
Do it while you do a new anti-fouling, unless you can't wait because you see alot of water coming in and the nylon nut is already all the way in. Then no other option than hauling-out.

Good luck.

Hi Mark, thank you very much and roger that, I have now tightened it as your information but about a 1/2 turn as it was leaking a lot.

So if I do need to replace the packing material I’m guessing you remove the nut to do this and this is ok while the boat is in the water?

Kind Regards Paul

In the Super Maramu there is a large nut at the top of the post.  You tighten it by turning it clockwise looking at it from above.  The general recommendation is to turn it 1/6 of a turn at a time and then wait and check for leaks.  Continue this process until the leak stops.  If it does not ever stop you will need to replace the packing material.
