Transom replacement

[Rum_Pirate]

My 22’0” center console Mako is powered by two 85hp Yamaha outboard engines.

There was a termite attack (longish story) and given by the 'nest and debris' the transom core should (definitely long term) probably be ‘repaired/replaced’.

There are a couple of chaps that 'repaired' their soft/watersoaked transom by cutting off the outer fibreglass sheath, removing the timber core, fibreglassing in two layers of plywood and replacing the outer fibreglass sheath.

I have come across Carbonbond CarbonBond Pourable Ceramic Transom Compound which they say is perfect for your next transom repair or new boat manufacture. CarbonBond Transom Compound - Carbon-Core Corporation

Carbon-Core Corp.formulates its Ceramic Pourable Compound with premium polyester resins and high strength ceramic spheres resulting in high tensile and flexural strength.

The questions that arise initially for me is that they state 'Uses : structural applications where high compressive strength is required'.

Although it does say it has 'high tensile and flexural strength' , it does not say tensile under the 'Uses' section of their site.

Have any of you dealt with a transom repair using this, or similar, product?

Advice, opinions ?

The transom 'core' appears to need replacement.

Possibility to remove top of transom, remove termite attacked/wet transom core and fill using this of similar material.

Rather than cut off outer face of transom, remove 'debris' fibreglass in two layers of ply and re-fibreglass and then paint.

Have you looked at the link? I’m amazed there is a market for such a specific application.

I did find this dated 2011 !!!!

It's snake oil; the tensile strength is miserable compared to even mediocre plywood, it might work after a fashion but in order to do the job 'properly' it's barely less work than repairing with actual plywood.

Search on youtube for “Boatworkstoday”
He has a series on replacing a transom on a Bertram with Coosa board, although expensive, it is the right product.

You missed the word before expensive ie ‘extortionately’.

On top of the price I have to pay freight, insurance and then 59% on that total as Import taxes etc.

Yes, it is a good product.
