Pulling Cable below deck...short sighted builders

Surely the "ultimate" RIB is one made to your exact requirements, something that at least half a dozen uk builders will do for you.

If wanting to pull new stuff through then try a good deal of talcolm powder along the cable you want to pull through, that does help, but if you really have limited space due to pipe size you may have to pull all out and then clean, dose of tal and redo all.

Yes I wished manufacturers would put much bigger pipes in or simple a run along the deck that you could potentially uncover.

We need a calsberg rib.

I use a silicone spray - seems to work well, not sure talcum powder is ideal especially in a damp environment - would it not be a bit messy?

Valid point. I'm sure there's water in the trunking on mine. The boat filled up with water after a particularly heavy downpour a few years back, and even with a tight witches hat grommet at the stern, water found its way in. I had to drag through new replacement throttle cable and the old stuff came out wet.

Can manufacturers drill the trunking to allow it to drain into the hull void? Worth noting that most if not all outboard manufacturers don't use tinned cable, so the cable that's submerged in the bilge is simply rotting away with corrosion.

Contemplating getting some sort of Heath Robinson suction device rigged up!

A stirrup pump might do it, but I don't actually see water in the ducting as a problem.

Most of it's not 'creating the ultimate RIB' though, it's them doing the bloody job properly in the first place so they don't create an unmaintainable showboat that has to be dismantled to its component parts to change a bulb.

Bit like a RR sport I guess...

Ref 'when your deck floods so does the hull', not if you've got decent witches hats etc on both ends, or no access for water to get in.

I'm actually starting to really appreciate the way my Ballistic is trunked-there's a hole through the deck either end. One end is inside the console, the other end has a witches hat. The trunking is very simple-it's a single straight length, flat against the hull with both ends open. It self drains at both ends into the bilge. I have an outlet with a normal expanding bung into my splashwell for anything that does get into the hull, which is very very little.

Agreed, but I was thinking more if the boat was on a mooring & filled with rain or after a "super stuffing" etc. The water would naturally run to the stern & could eventually overtop the WH, it would then run into the hull. You would have to pull the boat out to empty it, unless you had a second bilge pump under the deck. If the underdeck trunk is sealed, the worst that could happen is just the duct fills with water. IMHO draining the duct into the hull is compromising the integrity of the hull, it's no longer a sealed buoyant chamber. In a past existence, I have been sat in a RIB with water level with the top of the tubes & gear floating away, we got one of the dry boxes back 3 months later.

i'm not sure what i'll do, this is my current setup as of tonight-

still thinking of taping it up to stop rain/washing it down letting more in.

took about 30 mins to pull the new hydraulic hose through, nothing is ever easy!

cheers

I sealed my WH's with liquid neoprene. They don't leak. I'd have to have water above the level of my tubes to get water into the console too-all the hatches and holes are either O-ring sealed or silicone foam gasketted.

You need some proper trunking on that. As it is, it does need sealing/taping up.

Whoever spiral wrapped it needs their knuckles rapping too. I know installing new rigging tubes isnt' that easy, but there's no excuse for what they did there.

[Xk59D]

i assume it was RC that done it, could be wrong though.

ideally i want to install a tube but it is a job for end of the season, not the start.

so for now, i'm going to tape it up and call it good until the end of the season.

where is best place to get the trunking?

cheers

See if there's a specific kit for Suzukis. If there is, it'll make a much neater job.
The one for my Opti for example came with a proper threaded deck fitting that the trunk screws into.

If Suzuki don't sell one, the Opti kit isn't a wallet buster and should have plenty of room in as it's meant to take 2 fairly thick oil lines as well as the controls and fuel.

Nos, where did you get the liquid neoprene from? I'd thought about using a flexible potting compound or similar.

that's what i used Dave from rs components ex-panda foam round the cables then topped off with potting compound i glassed a toilet outlet around the cables to raise it 4 inches instead of a witches hat only because the old one had perished and didn't like the split ones.
my trunking is 4 inch land drain so completely drains into the bilge and out to the well.
for threading i use a conduit threader basically a long rigid plastic cable with a hole in to tie to and a bobble that rides over cables works really well.

This helps, this one is attached to an old control cable, it's expanding cable covering, what happens is the the plugs on whatever you're trying to pull through gets fouled up on something, this smooths it out, this is a household plug,

It's Black Witch. (IIRC that's liquid neoprene). It's stood up very well.

Love that solution!

I did mine by layering them up with gaff tape to get the same result, but it's a pain in the neck to get it and the glue off afterwards.

These are one solution to sealing the ends.....
