Exercising older thru-hulls

As you can see from my other posts, I am working to bring a 1966 Hinterhoeller 28 back to life after sitting in storage for five years. I see about 5 thru hulls that all appear outwardly to be in good shape. In fact I doubt any of them are original. It would seem wise at some point to begin exercising them and I wondered if I should hit them with a little Kroil or something like that before exercising them? What do you think?

Re: Exercising older thru-hulls

What type of seacocks are they? ball, tapered cone, other? Bronze or Marelon/acetal?

Re: Exercising older thru-hulls

Good question. They are ball type of bronze construction.

Re: Exercising older thru-hulls

OK, I think I'd be a little leery using Kroil or other penetrating oils -- many of ball valves have either teflon or PTFE surrounding the ball in the housing for a smooth interface with the stainless or chromed ball. I honestly don't know whether the penetranting fluids would do damage to the teflon/PTFE or not, but you never know -- it's certainly something to check thoroughly ahead of time.

You might want to try heating the housing gently with a heat gun...

Re: Exercising older thru-hulls

I know a fellow who claims great success using PAM cooking spray. If that doesn't work I'd amp it with WD 40. Remove the grease plugs if you have them; then lubricate from all available ports. When the ball is moving freely lubricate with trailer bearing grease and replace the plugs.

Re: Exercising older thru-hulls

I have a boat - in the water - with 4 frozrn through hulls from lack of use by the previous owner. Any suggestions for freeingthem up, regular exercise to prevent it from happening again...and how I might do all this with the boat in the water. Or even how to replace them with the boat in the water if I can't free them up.
