Transom Repair

[jorgeinmiami]

I am going to do my transom and at the same time raise it from 20" to 25"

I will be going from the outside and not use ply wood and use coosa or something similar.

My questions

What would be the best material to use?

How much of a lip do I leave around the area cut out to work with in replacing the skin of the transom back?

To get to the 25" transom what is the centerline measurement up from the bottom up to where the engine mounts?

Any of course any and all advise welcomed!!!

Thanks
