This is a good thread. It should be added to that sv owners page. I find myself looking in there a lot. Sometime I got a question but the search feature dont work so hot so its hard to find things sometimes.

I flipped the blue boat 2 times and both times water got in threw the lock. Do you guys have any thing you do besides taping the whole lock aria to keep water out? Its the only weak link now.

Here is what I did for floatation

Under the rear of the boat it just cut tightly and stuffed in.
The battery hold downs are cut tightly and stuffed ontop the batterys.
Under the top/cowl all siliconed in with 100% silicone.
Under the nose is the stock floatation.
