I get a wet spot coming up from under the deck about 1/3 of the way back from the bow. Look from the under side it lines up with one of the cross members. Think there must be a seam in the plywood at that member. Does anyone else have this problem and how did you address it.
 
Call your dealer, and I assume you don't have underskin.
 
Dealer put silicone on the out side of the plastic flashing last season. I think I'm going to do it myself this time. (Don't want to give him the boat for two weeks) .

No I don't have the under skin but I think if I remove the flashing that's directly in front of the rib and calk the entire cross member I'll do a better job than the dealer did
 
I'd have Bennington supply the underdecking and have the dealer install it. I don't think caulk is the solution. That is my $.02
 
Let the dealer ,do it . Use your warranty .
 
Plus if YOU do it, and it makes it worse, you would probably void the lifetime warranty (plywood)!!

LIMITED LIFETIME DECK WARRANTY
As a Bennington owner, you receive a Limited Lifetime Warranty on the 7-ply, pressure-treated, marine grade wooden deck. Since we fasten the rails and deck directly through the under structure, Bennington decks flex less and will provide you with a lifetime of enjoyment.

Are you original owner and or what year boat?

Yes I am the original owner of a 2013 24 slx. Calking was used by the dealer last season but he put it in front of the the flashing not directly on the cross member. I hate the thought of giving up the boat for two weeks this season.
 
I also had the water problem prior to underskinning my boat.  I would consider living with it during the season and having it done when it goes in to winter storage

Did you attempt any other fixes prior to the under-skin?

Nope, truthfully I thought it was normal, I didn't expect it to be waterproof
 
Why don't all pontoon boats have under skinning?!?
 
I seem to have a reputation here......

All I'll say is it has been a long 9 months with the wife pregnant. Throw in a Michigan winter and you get crazy. He is due any day so hopefully I'll mellow out once I am a dad....unlikely but you never know.

Yes Lakeliving most young couples I know have found having a newborn is very relaxing.  Oh and they all say they sleep so much better as well :wacko:
