Transom Repair - Core

edloh · #1 02-21-2007, 01:23 AM

Hello guys,

working from the inside. i have cut the core for my transom. as you know there is a gap between the core and the boat. should i back fill this gas with filler? i am afraid this would cause a hard spot and crack the hull. what do you think? thanks

I filled my gap between the hull and the transom composite in with fill and have had no problems. Infect I have never heard of any one having problems with hard spots in a SeaCraft re due.

Being new to Seacrafts,i'm a little bit confused about the gap you're speaking about.Do you mean between the transom skin and the core? or between the edge of the core and hull bottom and sides?
I just finished removing the rotted core from the transom of my Tsunami,and also did it from the inside.
I have all the grinding,cleaning,and cutting done,and will soon be laying up a couple layers of 1708 on the inside of the transom skin,before i put the core(marine ply)in.
Was wondering what gap you were referring to.
I helped a few friends in the past on transom replacements,and we always filled any gap between the edge of the core and hull with filler.Never had any later problems,doing it that way.

Regarding hard spots. The problem occures when there is an area of flexability adjacent to an area of rigidity. The flexible area moves and the rigid area stays put and you get a crack were the two meet. If you are worried about hard spots then just beef up the area that is flexible. I also am not sure were exactly you are talking about on your transom... are you talking about were the transom meets the sides of the hull?

I know the gap you are referring to... The small space between the edges of the core and the hull sides and bottom. I put down a nice bed of thickened resin (putty) before the core goes to place. Then we put the core to place and the excess squeezes out. Then I use the excess to form a nice fillet around the edges of the core.

The glass is so thick where the hull sides and hull bottom meet the transom, there is not a problem with a hard spot. Building a fillet and gradual layering of glass tabbing in that area will help in dispersing forces gradually otherwise.
