HELP!  My father in law has a Pelican Bass Raider 10e that has a small leak (takes the entire season to be noticeable) but every winter we have to pull it out and drain the pontoons because they're full of water.  Looking for any advice on locating and repairing the leak.  Thanks!

It's plastic right ?

How are you draining the pontoons?

if you can get into the hull just take it to an area that is completely dark and shine a flashlight on the inside of the hull.  Light will beam out of the leak.

I'd try a reverse water leak test. When the boat is out of the water on a trailer or off the ground some way. slowly fill them with water and see where it leaks out.

Pretty sure they're filled with foam.

Flex seal. It fixes anything!

I tried flex seal on mine, it came off first trip.

I would go with the reverse leak thing. I have one of these for small ponds. Maybe post in the thread called "Pelican Bass Raider thread" or something like that. For me I would fill it full of water put it on some bricks off the ground and see where it leaks. 

Those don't draft a lot of water, If you can't see a crack or hole doing a careful visual inspection concentrating on the corners, my guess would be it's stored outside and taking on water around the seam. I'm putting drains w/plugs in the top / back so I can mine drain as needed. If you find a crack you can google "plastic welding". I've also seen articles that talk about using melted plastic from a milk crate. 

There's a possibility that it's not actually taking on water, but rather moisture is condensing inside the pontoons. I used to have a Bass Hound 10.2 that had a plug in the bow so you could drain it because of that very thing. 

Pretty sure they're filled with foam.

Don't know about the newer boats, but mine that was bought around 2000 was not filled with foam. It did have two drain holes with plugs that could be removed at the front of each pontoon. Mine got two small slits, one on each pontoon, from me backing it up to the ramp for loading into my truck. Several hundred trips and it finally busted through. It would take on a small amount of water everytime out but was very easy to drain. Once the leak is found a plastic welding kit would do the trick. The kits I found online were around $50. I would have bought one but I sold the boat to a friend from work.

I have a bass hunter ex, it is a one piece hull and I still get a little water in it from condensation, the bass raider is naa two piece hull and they will get water in them were the hull is put together, some people take these apart and seal that seam
