[Alberg30] More Stuffiing Box Hose Replacement Questions

Tue Apr 23 16:19:18 PDT 2002

Tom... I think from what I've read of this post that you have just the same
thing as the other hulls. I would NOT go poking around with a screw driver.
That hose sounds just fine to me as you described. If the guy buys the boat let
him put that 2nd hose clamp on next to the stuffing box. There are gobs of
sealant on my boat also... just the way it's suppose -a-be.

Kindest Regards- Greg
