I am concluding the purchase of a 1989 Montauk. The boat has an automatic bilge (sump) pump that currently dumps through a hose draped over the transom. I don't like this loose arrangement, but do not see how it is possible to put a hull peneration through te stern quarter as I have seen on some Outrages. High up on the transom looks possible, but even there the glass looks thick.
Is there a common solution for this?
Thanks.

leave it draped over the transom, just zip tie it in place.

I have the same set up and have a plastic clamp at the corner of the transom that holds the discharge hose. It is cut just past flush with the transom. Works great and looks ok. You can see it on my personal page next to the bait tank discharge. It is the one with the black tip.

Mine is currently set up to drain over the transom. I was thinking of redoing it to drain into the motor well. Other than the unlikely chance of the drain hole being clogged, can anyone see a problem with this? I believe I saw some pics here of a 17' set up this way...

I've run my '89 both ways with no problems.

I had the same arrangement on my 1987.
One mod I wanted to do but did not get to is to get black smooth hose and route it along the steering cable and then add a 90 degree fitting facing aft. I also wanted to wrap both the cable and hose in loom to keep it clean looking.
I like all the cables and wires to be neat and organized. Hate the jumble of wires and hoses. Yeuch!

I run my 25' with the splashwell plugged and use a 1100gph automatic bilge pump. I did not like the look of the hose drapped over the transom and used pvc pipe with a few 90 degree elbows to run straight up and over the transom. I used a short section of hose to connect the pump discharge to the pvc pipe. I think it looks alot cleaner.

balene, dumping it into the splash well seems counter-intuitive to me, at least in some cases. Why do you have a pump anyway? If it's for convenience while you're boating than the splash well idea seems fine. But if you leave it active overnight or for weeks while moored, then you take a chance of having the splash well drain plugged or restricted by leaves or whatever. In that case maybe your pump just cycles and the boat keeps collecting rain water. I guess it also depends on the height of the splash well relative to the stern.
I know when I go high and dry at low tide, the boat often lies stern to the incoming tide. On stormy days I've taken on seaweed-laden water with the incoming tide. It's another way to collect a little seaweed in the splash well.
So I guess it depends some on how you use the pump.

I am strongly disinclined to dump it into the well. It seems to me that it needs to go overboard right away. I am trying to figure out a neater solution than just having the hose hanging over the side.
I get back to the questions that inspired the OP. Is there a fitting long enough to penetrate the tansom, and if so, what is the preferred placement?

Sorry, I got a little off topic there.
Can you weld? You could modify a standard drain fitting. Or machine a new one from brass cylinder stock. That's what I might do if I couldn't find a bulkhead fitting. You might look at McMaster-Carr or somewhere similar for some piece of hardware that you could adapt.

I just use a black nylon hose clamp on the stern. My view is that a bilge pump is not a "long Term" investment, a pump "change out" should be "Simple & Fast".

As you know the hull construction of a Boston Whaler is two layers of fiberglass with a bonded layer of foam. Any fitting or screw that penetrates the fiberglass needs to be sealed to prevent water saturating the foam.
Drilling a through-hull in the stern quarter is one solution. Given the open design of the Montauk, there is no gunnel cap or rear quarter seats or cap to hide the fitting. While it may meet your needs practically, it would, to some, be visually unappealing.
In looking at hundreds of Montauk's, I have never seen or read of an owner utilizing this method for bilge discharge. That in itself is telling.
In your 1st post, you state you are concluding your purchase. I would share the advice I was given when I bought my Montauk; use the boat for a year. At the end of that time, decide if the through hull method is what you want to do.

You are undoubtedly correct. I was just acting on twenty three years of large boat ownership, advice from the man who has owned this particular boat for the past ten years, and my own observation of Outrage hulls. Sorry to have wasted space here.

It was little frustrating when I first got the boat that there was no "Thru-hull" fitting available when thumbing through the marine catalog (I think we've all searched a bit for one). It's just one of those "Whaler" thing's due to the foam construction, when you think about it, the "Foam's" more important (unsinkable).

Balene -
There is no wasted space. This forum is for any and all questions, ideas and thoughts concerning whalers. A through hull is do-able, and you raise a valid question.
We support each other regardless of model, engine brand and setup.

Balene,
I'm wondering if a threaded piece of PVC would work to connect the "Thru-hull" fitting ? It's a good question, one we've all thought about, you are NOT wasting space, we love anything "Whaler", Idea's, question's, suggestion's, pictures, are ALWAYS "WELCOME" !
