BassBoat Drain area, below transom rot HELP!!

Hey all .. I have a question that I can not seem to find a answer for .. anywhere on the net doing searches.. I have a 1978 Hurst 15 foot tri hull bass boat has a small transom area , below the transom in a pocket , scalloped out area is the livewell intake, drain, and boat drain this wood was discoverd to be rotted while removing rotted tramsom, bassically all the wood in the boat was a complete loss due to neglect of the last owner.

My delima is .. I have now made a piece of wood to go back in the area of the drains, same shape and thickness as previous piece.. I just cant figure out quite how to reatach it .. Its too deep for a clamp .. have some made from 2x4's used for transom but the transom angle makes the drain board tilt.
The only solution I can figure out is to glass the piece of wood .. let it set few hrs.. then glass it in .. and drill small holes .. in the old holes fro drains and water instake.. use toggle wing bolts .. to keep presssure applied to the drain area so it will seal tight when cured.. aslo thought of wedging board against it to hold it till cured ... but toggle bolt sounds better to me .. what do yall think ?? Pictures of the area availible if need better clarity http://fatcat.faithweb.com/
Below is a picture of what Im taking about

 

Any way you can use a long board and wedge it against something up front to apply pressure? See Sketch

I was going to suggest the same thing as Lewisboats, if you have a stringer up forward you can clamp a block of wood to it and use that to brace against. You can also use a small bottle-jack if you can't fit any wedges.

transom rot

hey all ive seen this alot in older boats ,most of the older manufactures put lots of wood every then drilled holes in but didnt seal the inside of the holes which let in water and the rot in the area you showed i personally would not put wood back in. i would put several more layers fiber glass that would be just as strong and never rot out.

 

Thanx for the info but your about 8 months too late I finished my boat, I did put the wood back in but, I did use epoxy to seal the drain tube areas before inserting the drains and live well pump. Thanx for the info anyway though. What a project it was too .. Started researching how to do this at the end of march, put it in the water July 4th week end for the first time. Been doing stuff to it since then.. new carpet, new electronics, trolling motor, all new wiring and lights, great lil bass boat. Now looking for a bigger one 17-19 feet Now that I know I can do it my self. here is link to my boat finished and couple in progress pictures http://home.comcast.net/~northrivergeek/index2.htm
