Pontoon Boat & Deck Boat Forum

Pontoon has a pinhole leak somewhere. It apparently is so small that it’s not showing up on a pressure test. Had the boat in the water all day yesterday. Took it back to the storage lot and noticed an unusual amount of water coming off one of the toons. Went back this morning to check and sure enough there was a small puddle of saltwater.

I had a repair done to this pontoon earlier this year. We’ve Inspected the repair site and it’s definitely not coming from there. The guy that did the repair is a great aluminum fabricator; he’s just not a boat guy, so when he pressure tested it, he may not know where to look on a pontoon.

The dealership wants $300 just to pressure test the single pontoon. Then the meter starts running on the repair.

Any recommendation on someone who is good with pontoons but won’t skin me alive on the price? Thanks.

I see your boat in your signature. Doesn't Bennington have a " lifetime" warranty on the Hull? Something doesn't seem right to me if you're having several issues with leaks.

It's easy to pressure test on your own. A trip to the local hardware store and they can have you hooked up easily. Most important thing is to remember it's a low pressure test. You'll need to get a low pressure tire guage" atv guage works" . You just need a couple psi and a spray bottle with soap water mix. Look for bubbles!!!

Not in this case, no. I did the damage (not a warranty issue) so it’s on me.

Ok that makes sense to me. However it's still easy to check for leaks on your own. That price you listed for the dealer to pressure test is really high to me. When building my old boat we tested anytime we welded on it , building the transom/ adding lifting strakes.

You mentioned a pin hole in your first post. I had a friend take delivery of a brand new tracker pontoon with just the same issue. Noticed a slow drip drip drip out of the nose cone when tying it down at the launch after the madin voyage. It turned out to be from where the welding rod left the "puddle" after welding the seam. Looks like a dimple at the end of a long weld. That's an easy fix for any competent welder . It may be something similar on your boat.

My local marina and the local Bass Pro Shop referred me to the best sheet metal and welding shop in town. They both said that's where they job out that kind of work. Maybe follow that avenue and see what you can find.
