Well a week ago I bought a 1993 spectrum bluefin. I got it out for the first time yesterday and it was taking on water. I turned the bilge on twice and it pumped out a gallon or two both times. Then when I took it out I pulled the plug and water ran out for about 30 seconds. Is this normal? This is my first boat so idk what to expect. It seemed like a lot to me. We were out for about 4 hrs. It has rivets in the hull. Are they leaking? There's no holes that I see. Is there a clear coat or clear tape or something to seal up the rivets. Any input would be appreciated. Thanks

Re: Leaky boat

Don't know the Bluefins but I would say you have a leak somewhere. Can't say if it's a rivet or a fastener of some sort. Does this boat have a floor/deck in it?

Re: Leaky boat

Leaky aluminum boats are easy to fix.

Turn the garden hose on in the bilge and fill it with a few inches of water, look underneath the boat for leaks and mark them.

You can fix leaky rivets like this from the outside of the boat:

If you have leaky seams you can take your decking out and use products like Gluvit or Coat-it to paint over the seams to stop them from leaking. Gluvit and Coat-it are epoxy coatings especially designed for marine applications.

No it's not normal to get water inside the boat anywhere. But it is a very common occurrence. A 20 year old boat regardless of it's building material will usually have wood somewhere in the boat. In the transom and/or stringers. Wood is used for supporting the boats structure. Problem is wood will rot if it gets wet and over time will loose it's supporting ability. Being this boat is aluminum there can be leaky rivets - yes - but these can be repaired. Not knowing the boat I going to assume it is an outboard based on pictures I see, so I would rule out water leaking for the cooling system of an I/B or I/O.

You indicated you turned on the bilge pump, this tells me there is no automatic bilge switch wired into the bilge pump system (or it died). Get a automatic bilge switch installed correctly.

Now before you go all nutzoid over the leak try to find it first. As mentioned fill 2-3" of water in the bilge and see if it leaks out somewhere. Are there any live wells? Check if the hoses are tight. Check the transom for movement. There shouldn't be any movement other than a slight flexing. With the motor trimmed up, move the motor up and down and note any movement in the transom area. Some suggest standing on the lower unit of the motor to check for flexing. If the transom wood is rotted then there is a good likely hood major repairs are in order. This is doable yeh but a big headache.


If the boat has any hatches look inside them for water. Foam filled hulls can absorb a tremendous amount of water over time. Did the boat feel heavy and sluggish?

Re: Leaky boat

Thanks guys. I filled it with water today and not a drop came out. Yes it has decking. And yes it has live wells. The only other place seems to be the live well in and out holes. I didn't turn them on but it looks like it can go right in. The export hole fits a drainplug. So I'm gonna plug it next trip and see if that solve it. Thanks for the help.

Re: Leaky boat

just a suggestion - your livewell plumbing could be leaking as well. ex father-in-law's forester had every plastic fitting from the factory broken. replaced the simple resin fittings with glass-filled poly fittings.

Re: Leaky boat

A dry bottom is good when on the trailer! Glad to hear that.

Again at 1st it could be any number of things from a leaky rivet to a leaky fastener for a transducer to a leaky drain plug or livewell fittings. With a full deck on it I wasn't sure I wanted to suggest filling it with water which is why I didn't.

Re: Leaky boat

depending on the boat, if I am right, it may be a weekend of boat dissassembly to get to the plumbing.

Re: Leaky boat

Before I drained the water I jacked up the front so all the holes in the back were submerged and the in port for the live wells was dripping out the back. Should I buy that glovit or will silicone work? I'll see if that stops the water.

Re: Leaky boat

I had the same problem. It turned out to be the livewell pump,not the through hole fitting. I replaced the pump and that stopped the leak.

Re: Leaky boat

now that you isolated the issue to the livewell plumbing, you need to find where the leak is.

3M 4200 or 5200 on the thru-hull fittings. however if you have a bad pump (have seen the pump bodies melted from running them out of water), or a cracked fitting, you have to fix that.
