Subject: 72 Sea Sprint Arthroscopic Transomectomy (Transom Repair)

Note: since this letter, Michael has successfully repaired his transom. He has documented the repair, and has allowed us to put his documentation on our website. You can see what he has to say here.
Hi, couple of questions and a web site. I ordered some supplies from you last week - need an opinion as to whether they were enough.
Pictures and my plan are here:
This is a 16ft Sea Sprite runabout with a 125 hp evinrude outboard.
I ordered two quarts of CPES and two quarts of L&L epoxy. Do you think that was enough?
I'm considering getting a 1/4 inch aluminum plate(s) made for inside and out - is this overkill?
Thanks for the good graphics. Your plan is clever, and thorough.
I think you're okay on product quantities. One can't always predict how
much CPES the wood will absorb, but you've tapped this thing out so well
that I think you're going to be okay.
Same with the L&L Resin. Here it will depend to some extent on your
tolerances, but I think you're okay. Remember that the L&L Resin is VERY
strong and if you made 75% contact between the old and the new you'd be
just fine. You can also add coarse sawdust to the mixed L&L Resin to
stretch it out and expand it as a bedding compound. You keep it
flowable, but the sawdust adds volume. The result is also VERY strong.
We use this technique frequently as a means of saving resin.
The L&L Resin is not classified as a hazardous material so if for any
reason you should run short we can ship by Priority Mail or UPS Air,
whatever you select.
I don't think there's any such thing as overkill when it comes to making
boats strong, although I think one on the inside would be quite
sufficient. This is also something we have done when the owner will
agree to the (relatively) small additional expense.
When you're finished your transom will be far stronger than it was when
Come on back if you have additional questions or comments. And thanks
again for the pictures.
