Author Topic:   Bilge Pump for Dauntess 15

Has anyone put a bilge pump in a Dauntless 15? If so, what was needed and what did it cost? If there is a prior thread on this subject, please point me in that direction.

Why & where? The boat was designed to be self-bailing.

The tiny bilge compartment on the starboard side can be drained in a minute or two by pulling the plug while underway.

The compartment in front of the motor can be sealed by caulking the cover. I put a Beckson deck plate in mine to give access without recaulking. Others have suggested stuffing that space with an inflatable fender or such and leaving the cover off.

The boat sole should be above water. If it's not, then a bilge pump will be kept busy pumping out all the water that would come in the scuppers. /

What's the problem you're trying to solve? One of the reasons I bought my Dauntless 15 was for its self-bailing hull. I didn't want to worry about the battery and bilge pump keeping up with things while I was away.

I was planning to put the Dauntless on a mooring for a few weeks and did not want to find it full of water when I returned after heavy rains. Also, as prior posts have noted water does come in through the scuppers at low speeds (less if you use the ping pong ball type).

This problem could have been avoided if the control lines did not come out of an unsealed hole at the low point of the floor. Possible solutions could be a raised lip or sealing gasket around the this opening, that prevents the water from flowing into the bilge under the floor.

While a bilge pump may be overkill, I was just asking if anyone had experience with it.

If pulling the plug while underway is the preffered solution, so be it.

Thanks for those links. Your photos nicely illustrate the situation.

The boat will self bail. Mine takes on water through the scuppers when I climb on the ladder and swim platform. Then once I get my weight off the stern, the water drains back out. If yours has enough stern weight that there is standing water back there, that's the same amount of water that will be there after a week of rain. The rest will drain out the scuppers.

Jim - you're welcome ... just trying to help.

Its true the boat will self bail. However, what happens is that when it rains, the water that falls on the deck forward of the center console will partially make its way under the console and into the tunnel that runs from the console to just forward of the transom. Since this is covered, the whole thing eventually fills up.

I have had that cause problems with wiring that runs through there. I am in the process of replacing the lighting wiring since there must be a nick in the insulation somewhere that lets water in and shorts out the lights (until it dries out).

Since my boat sits on a jet dock, its easy to drain the boat before I use it. However, I too am interested in a bilge pump arrangement - just to avoid having to reach down in a cold wet bilge every time I want to take her out.

Anyone put a pump in here? Love to hear about it.

I do have new scuppers (the ping pong ball type) that work great.

You raise a good point. On my boat, the aft deck compartment (over the tunnel end) is not caulked or waterproofed in any way. Even when we're out for a day trip, I'll have water collected there from water that came in from the scuppers from launching or too much weight on the swim platform.

The other end of the tunnel under the console has a boot that may or may not be water tight (probably not - I haven't looked closely).
Might your concern that the water that fills the tunnel enters there be mistaken for water that fills in from the stern? In either case, some caulking might fix it.

My main goal was to have a boat that wasn't dependent on a working bilge pump. I hadn't thought things through beyond that.

Thanks Paul,

I will look into that, but it really seems like the water is coming from the tunnel side. I can't imagine that that qty of water was coming in from the cover.

The reason that I say this, is when it is sitting on the dock, there is a slight rise from stern to bow - due to the dock and hull shape. So, since the bottom of the scuppers is almost slightly higher than the top of the little screw in port, there should never be all that much water sitting there. It almost seems like there is water in there higher than the top of the screw in port.

I'll look to see if the caulking is there or not - it would be an easy fix. I really doubt that any boot over the tunnel under the console would be very effective.

Thanks for the thought, I hadn't considered that the caulking could be teh problem.

Great idea about putting access cover on splash well area cover. I took my factory cover on my 17 Dauntless off once and it was full of water. Obviously the factory sealer didn't get the job done. I cleaned and resealed but I will now make a winter project to redo and install access cover. I like the idea to be able to remove and use a rag to remove any water that may collect there. Especially before a freeze!

This is one of the many things that make this site great. Many inventive people sharing ideas that apply to numerous models!
Thanks for the tip and links that show it well.

I opened up the stern hatch on the starboard side today and it was full of water so I pulled the drain plug to let it out. I'm concerned though that water may have collected in the tunnel too because of overflow from the compartment and may be still there. Is that possible, or is designed so that once you pull the drain plug all water will come out of the tunnel? Should I be concerned about this damaging the boat?

Also, Paul, can you tell us what size Beckson Deck Plate you used on the compartment in front of the motor? I opened mine up today and it was full of water too.

I'm a little confused. Are we talking about the access cover that is located near the stern on the starboard side of the boat? Or are we talking about adding ANOTHER cover just forward of the stern in front of the motor on the main deck of the D15?

My D15 already has a beckson screw in access port on the starboard side. Its part of a rectangular black cover from which the control cables protrude on their way to the motor.

Sorry for the slow reply - haven't been reading the forum for a few days - have to get my priorities straight.

The Beckson plate appears to be the DP40-W from reading the West Marine catalog. I threw out the package from mine. The 'plug' is the same size as the Whaler deck plug on the starboard aft. The flange is a bit larger than the one Whaler installed, but it still fits OK on the plate below the motor.

JohnJ80, I added the 2nd plate on the plate below the motor to enable bailing the compartment covering the lower motor mounts. The first URL in my first posting shows a picture.

JohnJ80, I was talking about both the access cover that covers the drain plug on the starboard side of the boat and area in right in front of motor.

I'm concerned that water may remain trapped in the tunnel even after pulling the drain plug. Does anyone know if this is possible?

I added the beckson deck plate like Paul and it works well (Great idea Paul). I still seem to get water in there. Guess I didn't seal it well.

I also sealed the starboard compartment with the drain plug (it came unsealed), but I've created a problem where the all the water doesn't come out of the boat when I wash it. Oh well.

I think I'm coming around to the idea that the cover over the drain plug area needs to be caulked. I just hauled the boat today and there was standing water over that cover. I think it happens because their is a 1/4- 1/2" lip on the bailer hole. So there is alittle water that doesnt drain. If the cover isn't water tight, then it just drains into the bilge.

I'm going to fix that this spring.

I think I will also add the other inspection plate that others talked about. Anything give any thought to putting a drain in there with a drain plug that drains to the deck? That way you could just open the drain and let the accumulated water run out the scuppers. With the drain plug in, its watertight.
