I hope they didnt ,,the weihgt of the foam that i took out from around the tank was water loged and very heavy..if he whole floor has the foam i am sure it is water loged too ...my floor is solid and i don't even want to think about riping it up.....

I've had (2) 79's. The only foam is around the tank.

Think mine is just around the tank on my '89. I could use a new tank...don't know how much there is to it. If you replace it do you need to use more foam. around it or can you go with out?

you would have to get tabs welding on the tank and then glass in some mounts so you could screw the tank down if you dont want to foam in. ultimatly the foam with rot the tank again.

It certainly will, foam holds mositure and rots tanks and stringers. Seabird also built an exact copy of the V20, a friend had one. Powered by an unreliable 155 OMC, it sat several inches deeper in the water and ran so much smoother than my V. It turns out that every inch below the floor was filled with late 60's vintage foam and totally saturated. The extra weight made the boat ride very smooth, but soon became an unusable piece of junk. Keeping the bilge area dry is very important. Foam makes that impossible.

I was going to drill a few small holes to see if there is foam in the rest of the floor but after reading some of the posts i think its safe to say that wellcraft only used the foam around the fuel tank........poengine33

Mine is 84, foam around the tank only. By the way, last time I looked at the entire tank, noticed that the foam was forming a little wall at the aft center top area, where the water drains out from the top of the tank. I removed all the foam from the aft rear top edge, and now water just flows out to the bilge.

I also remember that I removed the port side chair base, because the floor roted and could not support the seat anymore, and to cover the hole, I cut the floor and installed a 10" rectangular floor hatch, so the bilge there could be used as storage. I found no foam at all in that area.
