I have an 2009 Montauk 170. The wiring and cable channel from the center console is accessible through a removable port at the rear of the boat. I am wondering what happens if you get water in that cavity. Does it communicate with the bilge?
Thanks,
Al

Al,
How are things in LA? I found this diagram for harness installation at whalerparts.com, it's a good source of information. Appears water will make it's way to the bilge sump.

Thanks Number9, good to know about this parts site!
LA is great, a beautiful New Year's day. A little cool in the 50's.
I am going to get my inspection mirror and light out and open the port up and take a look. There is a grommet there for the wiring for the sump and livewell pump but it is not a drain. I am thinking the bilge pump catches the runoff from the deck only.

Al,
In one of those diagrams it looked like there was a cut below the grommet the pump wiring goes through. Thought there might be a low spot below and outboard the grommet the tunnel drains to until that overflows into the bilge sump? Will be interested is knowing what you find.

Short answer: yes.
Long answer: The way in comunicates may differ from year to year on the Montauk 170 because of the changes in model year design, especially with the years that incorporated an optional aft live well. My 2006 model year Montauk 170 communicates via a cut in the bilge to allaow water to flow from the wiring duct/channel to the bilge. There is at least one thread on this site where people complained about the efficiancy to said cut in the bilge and some people opted to modify the cut to suit their perception of how this communication between bilge and duct should work.

I note on the first diagram provided by numbers9, of the bow light wire arriving at the bow via under deck. However, on my 2006 170,it is routed out the stern and travels up the starboard side under the black rubrail to the bow
I have noted as well that the water does drain through to the sump bilge. I tested this by pouring water in via the inspection hole.

number 9 and friends,
Finally had a chance to get to the boat and look. The drawing
shows the slot and it is there. It is cut below a port where the wires and hose to the sump pump come in. This slot is cut to allow the water to run out of the wiring/cable channel into the sump.
Interesting to note that if you have water showing at the deck level outside the sump and live well, you have quite a significant weight of water in the boat because the under-deck channel will be partially full. Therefore it really is best to leave the sump pump on the automatic setting so the level switch will automatically remove the water.
The tech at the dealer suggested that I only turn it on when I see water on the deck. In that circumstance you are wasting a lot of energy hauling water you cannot see below deck. So I will be placing the switch in the automatic mode from here out. Normally I don't get much water in the boat but the automatic switch will take care of any that comes in and keep me from spending fuel to carry water I don't know about.

As has been discussed here before (even with pics I think), not all boat have this "slot" cut under the rigging hole in the bilge.
My '08 170 did not; I drilled a 3/8" hole under the rigging hole to allow the unseen part of the bilge drain into the viewable part of the bilge.
Alphonse posted 01-12-2010 11:13 PM ET (US)
Joe, without the drain it could hold quite a volume of water couldn't it. I am guessing 15 gallons or more (i.e. 100+ pounds)
I am going to make sure the slot in mine goes all the way to floor of the cable channel. I know I being paranoid about this, but there is not need in hauling water around that you don't know is there.

I don't think it could hold any more than a 1/2 gallon or so. Any more than that, and the water would spill out over the rigging hole that the bilge pump hose passes through. I drilled the hole so that it would not hold water under the step, where the rigging area continues to.
