Re: New boat, water in the bilge

I mentioned "Ski Locker" because it is sometimes difficult for water in the bow area to get around them. And, many ski lockers drain any trapped bow water THROUGH the locker. Drains at both ends. Take a look. One drain forward, one aft?

I very much doubt a bellows issue on a new boat.

We certainly hope you're right about that!


Even a brand new boat could have gotten some rain water and it was probably WASHED by the dealer before delivery.

Yeah, but you haven't been following our boat saga. We bought the boat in MAY, and once we got it home, the trailering had knocked off some cracked gelcoat. We took it in early June to a repair shop before ever putting it in the water. They then kept it 5 weeks. So it's been on land and NOT washed for 2.5 months - so nope. This is why we're perplexed.

I haven't seen anyone mention the ice in the cooler melting and running into the bilge. That can make a couple of gallons easily.

Dude, none on board. We do know that meling ice = water. :D

Start by taking a screwdriver to every hose clamp on the motor and each through-hull fitting.

light test: at night on the trailer put a drop light up in there. run the motor up and down.

OK, took a screwdriver all around the rubrail yesterday, and inspected it. Most of the screws were fully tightened - the only exception were a couple that I tightened up 1/8th of a turn or so, and the two screws on the swim platform, closest to the stern - one of which was quite loose. But I don't think that bolt is through-hull, so I'm not too excited.

We also jacked up the prow, so that the ski locker drained into the bilge. This time, when we removed the transom plug, we drained water. So we learned that the nose has to be waaaaayyy up in order to drain the bilge water that's left from the pump.

We *might* take the boat out on Friday, before our big jetski jamboree weekend, and I'll be interested to see if that helped.

Re: New boat, water in the bilge

I don't think you need to worry about this yet Sandi but certainly something to look at in the future, your exhaust runs water through the manifolds and over time they wear out and need replaced, look for some water trickle near where the manifolds bolt to the block, mine are getting replaced this off season but my boats a fair bit older then yours, I think most here would say to check this more frequently as your boat gets older, I don't know of anything you can do to prevent this its just one of those things, when I winterize I drain my block of water and then I put antifreeze throughout my motor, so I feel pretty fortunate that I have gotten 14 years out of my manifolds.

Anyway you really need to learn to judge your water intake as you get more familiar with your boat, yeah I would expect a dry boat with the use you described but 2 quarts is not a lot and I think you are probably in fine shape, water can absolutely sit in your boat for a very long time depending on if it was stored properly with the bow up high enough to drain and even then water can still sit behind a bulkhead and need to be shaken loose while driving or whatever.

I would suggest you and your other half make certain that you have an auto bilge though and that it works properly, this will make you sleep better knowing that on overnights when the boat is in the water even if you do have a small leak in the bellows or some other area your bilge will automatically pump the water out, a quick way to check this is to simply put the pug in and run a hose into the engine compartment, and fill until your bilge turns on and pumps the water out, its important to note that your bilge will not get all of the water out since it will stop when the water drops to a certain point.

Re: New boat, water in the bilge

It's typical to have water in a new boat, or one that has been out of the water for several months, until the planks in the hull swell and seal the gaps. You should have oakum between the planks to seal them.

This is awesome lol! I remember being a kid and pumping water out of Stewart Knockabout wooden sailboat. No bilge pump, only a pump that look like a tire pump.

Re: New boat, water in the bilge

Yup, my family had a Beetle Cat back in the 'old days' . . . oak planks . . . it would sink for the first week or so after we put it in the water. Had to take shifts to go out and bail the boat out a couple of times per day.

My Dad finally got the idea of filling the boat with about 6" of water while it was still on land and making it pre-swell. Seemed to work better, but not 100%

Sandi - keep looking for the source of the water . . . it may be a combination of things. I'm still chasing the source of bilge water in my boat and it has been in the water for 2 months. I just realized something this weekend . . if I leave the transom door open, then rain water does not seem to drain into the bilge. I guess the closed door causes water to pool up on the cover and then drip onto the rear seat. It is things like those that take time to figure out, etc.

Enjoy.

Re: New boat, water in the bilge

My boat lives on its trailer most of the time. Some weekends I leave it tied up at my neighbors dock. On these nights she takes in about a gallon. I have sat in the boat with a flashlight, filled the bilge and looked for leaks, checked the exhausts while running, etc. Still can't figure out where the water is coming in!

Drives me nuts.
