Garmin Loose cables

Iíve added a Garmin 240Blue Fishfinder and 176C GPSmap to my RIB.
Having used the gimble mounts so that I can remove the units for security when not in use, Iím left with the power/data cables hanging out of glands in the console.
I did toy with the idea of short cables and aftermarket water proof plugs and sockets, but the cost of the 13pin item for the Fishfinder was prohibitive and I donít really want to add extra joints into the circuit.

Anyway, phoned Garmin to enquire after some blanking plugs to stop moisture getting in the ends of the cables when not in use, and was told they do not produce them. I asked if they had any suggestions, and was told to ďwrap the ends up with insulation tape each timeĒ. What a professional solution that is!

Next idea was to get hold of some spare sockets from the back of the units, I could seal the backs, set them into the console and plug the loose wires in when not in use, so sealing the ends.
Phoned Garmin again, and was told they could not supply direct to the public, I would have to go through one of their dealers.

Both the dealers I phoned said they could not source parts, so I was back on the phone to Garmin, a different contact to before said it would be impossible to supply the spare sockets to either the public or a dealer, Ďwe just donít do ití was the reason. What do you suggest I do? Was greeted with Ďwrap the ends up in insulation tapeí.

After having a major whinge, It was suggested I write to the CEO in America and suggest Garmin supply blanking plugs as other makes do. They would not supply the name of a senior manager in the UK.

Itís become a matter of principle now rather than cost.
Iíll come up with a solution to this problem that others must have, and post the results, unless anyone has already solved it?

I completely sympathise with you about this, although not the same subject and slight different i've had a simular run in with a major manufacturer.

I've just purchased a yamaha engine, on the yams you have this neat little plastic screw bit that unscrews and allows a hose connector to be screwed into it allowing you to flush the engine through without running the engine, but i've been told you need the exact fiting as the thread is different to anything you can buy in a garden centre or DIY store. So on Sunday i approached the head engineer at the Yamaha stand and asked could they supply me with this part....the answer i got was no and currently Yamaha dont make this connection and the reason hose lock or any other type of fitting does not fit is because the engines are made in Japan where they use a different size thread .....Doh !!!

They have admitted its a big over sight and they are in the process of making the parts now to be released soon, but what a silly thing to scupper such a great engine !!

I've been told that you can use a normal hose connector fitting but to be careful screwing it into the engine fitting because it may strip the thread.

I have a Hummingbird sonar which is 10+ years old the plugs have survived so far with out protection!
I do put a blob of Vaseline on them now & again.

You have to be careful with those as not all engines have them. A member of the sailing club was about to unscrew the gearbox drain plug and put the hose into that when I managed to stop him! The same member was caught weeks later flushing the enngine through with the muffs on at half throttle in gear!


Is there no way of bodging the attatchment with... you've guessed it insulation tape?

No the flush pipe comes out through the top cowling and has a connection which you need to unscrew, this then attaches to a normal garden hose for flushing, once finished you MUST re screw the connections together or the engine wont be geting any cooling water when you next start the engine.

So no gaffer tape wont work !!!

Hozelock connections fit but they are not the correct thread diametre, this means the parts dont connect properly, and there is a potential to screw the thread up on the engine !!

Firstly the engine- I have run the same Yam system for a season and have no problem at all using a hoselock fitting screwed in finger tight although it took me a while to find the right one. The comment about the engine block confused me slightly, I unscrew from the end of the hose that terminates on a blanking plate and then fit the hoselock and this has worked fine.
Secondly the garmin connections, I have a Lowrance unit gimble mounted and have the same problem ie no blanking plugs. I haven't bothered protecting because the boat is always covered when not in use. If you decide to seal try something like a finger off a marigold/surgical glove or if you really want to open yourself to ridicule a condom. One of the reasons I didn't go down these routes was that I thought trapping any moisture around the connections might have a worse corrosive effect than allowing them to breathe.

Are you saying that you want to protect the connectors that go into the units when they are disconnected? When I first read this I thought you had cut the connectors off!!

Real easy way to protect the connectors is to stick a small plastic bag over each one and wrap a couple of elastic bands round the neck. Not pretty but effective, you could also stick a small bag of silica gel in just to be on the safe side.

As Nick says, a blob of vasiline or silicone grease should also do the trick if the boat is covered when stored.

Edit:- You stole my thunder woot, too fast for me.

I think you'll find the Garmin connectors are gold. They shouldn't corrode.

loose connectors

Ours hang loose (Ooo-err!) but are usually covered by the canvas console cover when the instruments are removed. None of the instruments are Garmin - an Eagle f/finder, Raymarine plotter and MLR GPS. All survive OK (so far!) without any grease, tape, plastic bags or other stuff. That's done it, they'll probably all fail on the next cruise after I've said that...

We also use a hozelock attachment for flushing and it's fine - but I'm always careful with threads. Remember the "experts" rule for thread tightening - torque it down until it starts to strip, then back it off half a turn. Perfect!
