THRU HULLS

[island time]

My starboard side thru hull for the engine is leaking thru the handle seal. Are rebuild kits available or is it better to just replace.

[James Power]

Try cycling the handle from open to closed a bunch of times. This may stop the leak. If not rebuild kits are available from Forespar. Lubricating the seal when ever hauled and exercising the seacock on a regular basis will help with operation and longevity.

Hope this helps

From my emails with Jake in tech support with Forespar this week. You'll pay way more for shipping than the kit.

If it is the handle, there is a kit to replace the o-rings in the handle (Part# 930404). It can be ordered from our website link below.

As far as the stiff handle is concerned, you can try lubricating the ball (we use Marelube) to see if that helps making operation easier.

I’m not sure if this was part of the question or not but the seals can be replaced with the boat in the water.

Alan,

Is that using the plunger on the outside approach Dick talked about at the owners meeting?

I would have assumed you can do that with the seacock closed, but a different forum showed a significant stream of water when this was attempted. He said the o-rings and handle "blew" off the mount and he had a good leak going for a bit. I wouldn't want that.

Looks like a fun little job to service with the handle on the bottom.

Andrew,

The easy way is with the plug on the outside of the hull. I have not done that but doing it from the inside is easy. You take the handle off and the old O ring out, greese it and put the new one in. You will get some water but not a lot. It is a very easy procedure.

This link will show you what to do. It is for a different model than the valves on a PDQ but the procedure is the same.

Several months ago I accidentally broke the Stbd raw water intake seacock handle when I stepped on it while trying to find a place to put my feet....
I ordered the correct handle replacement kit from Forespar along with a tube of Marelon grease.

Finally got around to doing it this week:

* I had to use a vise grip to rotate the seacock into the OFF position as the handle broke right at the point it connects to the round body.
* Once I rotated it to OFF, I pre greased the new handle with the new larger O-ring and got everything ready. Since there is a strainer outboard on the
hull, you cannot use the handy white plug in the handle to seal off the water flow....you have to do it while seacock is closed but in the water.
* Using a mirror and a stubby phillips screwdriver, I removed the screw holding the handle in and wiggled off the broken remnant of the valve handle.
* There is a dribble of water coming from the handle area but not enough to cause concern or panic.
* Using the mirror and a small pick I removed the smaller internal O-ring.
* Applied Marelon grease to new smaller O-ring, valve body and new larger O-ring on valve handle.
* Reinstalled new valve handle in seacock body and reinstalled screw and noticed that some grease squeezed out form the valve body (which is good).

Exercised handle several times and no leaks detected (even after several hours).

I carry handle kits for all the seacocks on board
