Hmmmmm, Drumbeat seems to take on water through one of the prop shafts (seems to only be the starboard shaft  :-\). I've tried a bit of grease at the top of the shaft but that doesnt stop it, only slows the flow.

Anyone know if ACTion or others make an automatic bailer? Sure I've seen a few other large models down the lake with them. Seem to pump out water when it gets to a certain amount. Any ideas?

Have you tried taking the prop shaft right out and pump grease in at the bottom end. Put your finger over the top of the tube and push the prop shaft slowly up the tube releasing the pressure carefully. I had the same problem with one of mine, this cured it.

Also, do you have a close fitting washer between the prop and the end of the tube? This will tend to seal the tube when the boat is going ahead. A little bit of leakage is normal enough, even full size boats have it but if it's sufficient to require a bailer then there is something wrong!

Another tip is that if you can build a "dam" in the hull just forward of the inboard end of the tube it will confine any minor leakage to a limited area where you can easily suck it out with a syringe.

Thanks for the info. There isnt a 'flood' of water but it is noticable. The tubes and shaft are provided with the kit. There's about 4" of shaft between the prop and the tube it runs in so there's no washer to fit against the end.

In the Model Slipway kit review it is suggested to use a small o ring at the base of each shaft to prevent seepage of water.

Richard is right, an "O" ring will probably help.

You could put a small collar on the shaft in front of the tube to bear against the washer or O-ring.

Removing the prop shaft, and restuffing the tube with a small amount of grease should work.

I was expecting a tutorial for taking on water,...
I am an expert at that...

My simple, quick and easy way is to drill a smallish hole through the prop shaft outer casing (actual shaft removed). "Obtain" a smallish hyperdemic syringe and trim the bit where the (non-existent) needle goes to a neat fit in the hole. Replace shaft. Fill hypo with whatever and squeeze into hole. I cover the hole with a tight fitting "terry clip" that can be slid oaway from the hole. Hope this helps. BY.
