My 86 outrage has a new home. I always kept it on a trailer with the plugs out. The new owner is going to keep it in a slip. Problem is it doesn't have a bilge pump. Where do you put one?? Where does it draw from to get the water off of the deck? I'd like to help him as much as possible so any ideas would be greatly appreciated.

You don't say what size Outrage it is but I will presume we are talking about an 18'.

The 18' Outrage was a deck plate or pry out in the starboard stern corner of the cockpit. It is next to the tunnel exit where all the cables come up from the console and go to the motor. Under this deck plate is a sump area designed for a bilge pump if you want to install one.

Any water that enters the boat will drain to this sump area via the the tunnel exit point.

You can install just about any pump you want and then run the hose out the tunnel exit and over the splash well dam into the splash well where it will drain overboard. If you prefer, you can run the hose over the transom or through a through hull fitting but the latter seems rather silly given the proximity of the splash well/transom to the bilge sump. Either way it's a very simple installation.

I never needed a bilge pump on my 85 18.6 Outrage... When docked, I always left the plug out. Any rain just ran in, and ran out as the thing floats high enough to ensure a self bailing capability. Note that the corner "bilge" hole always has about 6 cups of water in with the plug out. Never a biggie for me. Mav

How does this same issue apply to a Montauk ?Mine will be on a mooring and I was contemplating a bilge pump as well. Thanks for the help.

I've owned 2 17s, and neither was self bailing in that each would fill up with a good bit of water if the plug was left out - enough to get your shoes plenty wet. If mooring a Montauk, I'd install an auto bilge pump in the center stern well. Mav

I have a Rule Platinum Automatic Bilge Pump 500 GPH in my `16 Currtuck and I love it and I run the bilge hose over the back of the transom as has been suggested, I use clips 1 on the top of the transom, and 1 half way up the transom. Jack.

Thanks for the replys.Does one have to worry about the battery going dead? How long should the boat be able to sit(normal rainfall) without running before the bilge pump would kill the battery.Thanks for the help.

The best way to avoid a dead battery is to install 2 batteries (one deep cycle and one with high Cold Cranking Amps "CCA")on a Perko switch. Always leave 1 battery, usually the deep cycle, on when moored. If the pump runs enough to kill that battery, you probably aren't using your boat enough to justify mooring! It helps to also have somone keep an eye out on your boat if it sits for a long time (several weeks), or during the monsoon season. When you start the boat, switch to the "full" battery, and then back to "both" when running to charge up the depleted battery.

You can also install shore power and "plug in" your boat, but is usually a "$200 saddle on a $20 horse" with any boat small enough to be trailered.

It helps to put in the biggest capacity pump that makes sense. Just because you have a smaller boat doesn't mean that you can get by with a smaller pump. When a small boat begins to fill, you have less time and less buoyancy to work with before the boat swamps or turns turtle (which BW's never do). Also, in general the shorter time the pump has to work to throw out a given volume of water the less power necessary (more volume in fewer cycles).

If you use the boat with any regularity...once a week at least, the battery will be plenty to start the motor and recharge. Assuming: battery is in good shape, and you are expecting normal rainfall. This is what I do, never had a problem.

I have owned many Whaler's and I know from experience that Montauks and Outrages collect rain water and will absolutely drain the battery dead if you run the bilge pump in automatic mode unless connected to shore power. What I used to do is run the pump in non auto mode. When I go down to the boat for a ride I then turn on the pump and pump it out. The water will collect to a certain point and then just drain out the back of the boat.
Or on a 17 Montauk you can install a 1" brass pipe on the port quarter at deck level going thru the hull. The boat normally list to port because of battery weight. This thru hull pipe allows water to naturally drain out of the hull " self bailing". Just make sure the pipe is installed and sealed correctly so water doesn't penetrate between the liner and hull.

I have done this to many boats and it works perfectly!

Just my two cents.

For reference, BW's factory installed bilge pump option, all Outrage's 18-25', was a Rule 1500 GPH pump, with a conventional Rule float switch. This model pump, incidentally, is one of Rule's MOST RELIABLE products, for some reason. They last and last. The one that came new in my 25 Outrage is still working fine, and has outlived three of their float switches!

For all Rule pumps, I recommend their little (one size fits all) dome shaped filter screen to keep the pump from jamming up.

With the Platinum Series checking for water every 10 minutes, I have let my Currituck with Mooring Cover in the dock for 3 weeks unused and it still cranked fine, that is with an AC Delco Marine Starting 27 Series Battery. I love these batteries, the best I have used. I guess it all depends how long it sits and if the boat is covered. The regular Auto Rule doesn`t cycle like the Platinum, so it should not drain battery at all if the boat is covered. Jack.

I did an experiment yesterday, My montauk is still on the trailer in the driveway, I live south of Boston and we got a crap load of rain yesterday. I have a new deep cycle group 27 battery that is freshly trickle charged. In just on day of heavy rain the pump ran nearly all day in automatic mode with a float switch. Today I went to start the boat and it barely had enough juice to crank the engine and start it!

I just can't beleive that some of the other forum members don't agree.

Mike, I think the difference in your test and some are that your boat was uncovered, and some are Mooring Covered as mine is, so it is deffinately 2 different situations. I highly reccomend a full mooring cover on a totally open boat such as whalers, if not and you only cover the RPS and Center Console, you will have a pump that runs alot if it rains. Jack.

Ive got the Rule with the built in float switch on my 15 Sport. I wonder if that uses less juice then the computerized ones that check for pressure impeller .
Anyway Ive never had any low batt. issues thus far this season BUT the rain collects in the cover then I let it pump out.
Maybe im just lucky , but I use the boat couple times a week @ least thats got to help.

I currently own a 17 Montauk. I keep the boat uncovered in a slip pump on automatic switch. Never had a problem with battery on this or any other non bailing type boat. However I will always start boat within a couple of days after any heavy rain. Also replace battery other year regardless of condition.

It would be great if I could check my whaler for water every day when in the slip but due to my job standing 48 to 72 hr duty in the CG I can only check it once a week or so.
Yes a full mooring cover would be a great investment, does anyone know who makes a custom cover that fits the montauk that you can buy over the counter and not pay a canvas guy $$$$$$$$$$$$$$$$$$$$$$ to make one for you?
If anyone has a used mooring cover for sale in good shape I would consider buying it.

In your experiment in the driveway, were the plugs in or out? If they were out, I am baffled. (Silly question, now that I think about it - of course the plugs had to be in when it was on the trailer, or it wouldn't have collected any water at all!)

My experience with my Outrage 22' has been that moored with the plugs out puts *way* less stress on the bilge pump than with the plugs in, unless there is enough extra weight (batteries, kicker, etc) in the stern so that when at equilibrium (with the plugs out) the static water level is high enough to allow passage of water from the plug/drain sumps into the livewell where the stern bilge pump resides. If there is that much weight, the pump is being asked to run almost all the time, and you'd be better off with the plugs in. At least then you'd only be asking the pump to run when it rained.

If the static water level is below the passage from the sumps to the livewell, the only water the bilge pump gets asked to deal with is that which "accidently" gets into the livewell by running under the lid; the rest just runs out the plug holes in the drain sumps.

I bought a cover from Cabelas and it fits like a glove. Cabelas acts as a middleman for the company that makes the covers. If you don't find the exact one you need in the Cabelas catalog, call them and get in touch with the company that makes them. That company makes covers for montauks with and without rails and the covers fit great.

Yes the plugs were in on the trailer. Also when my montuak is at the slip and I remove the lower plug water naturally comes in due to the weight of the engine, battery and VRO tank, even when im not in the boat. So if I left my plug out and the pump in float switch mode it would constantly run. Did you read my post about installing another drain tube on the port quarter just outboard of the battery? It works great! It makes the boat self bailing!

I have read your post now - sorry I missed it before. A self-bailing Montauk should be a patentable idea!
