There is a volume calculator here and there is a Product data sheet pdf.
My V20 25" transom took three buckets $185 per 5gal bucket

When I tried to buy Arjay, I could not find anyone selling it. A chain of emails lead me to Carbon-Core CarbonBond Transom compound. It is the same thing as Arjay & the old 3M NidaBond pourable.

You need to try and find a local seller because shipping will kill you. Use the Contact Us and ask them for info

i wonder if that stuffs anything like seimens putty. when we were building the almost 900 foot carbon fiber zumwalt class ddg1000 destroyers we used a lot of that stuff. hundreds and hundreds of tons of it, literally. the navy was/is in love with that ****. and i dont blame them. we would spend millions and millions to build scale models for testing purposes. we would load 20-30 foot tall balsa core carbon fiber deck houses that took over a year to build onto barges for the navy to take out into the gulf and try to destroy them. the results were extremely impressive!!! and we learned a lot. proved a lot of theories that our mad scientist came up with that the industry will still call bs. like the proven fact that quarter inch step backs in a layup are twice as strong and ten times less likely to delam than four inch step backs! same designs failed at 20 g shockloads when 13 mil stepbacks survived 40 g's which was the max they could go. but most guys brains cant accept that. but i worked with the team that invented the VARTM process, whats commonly known as vacuum bagging. these guys were determined to do what the industry said couldnt be done

sorry, im rambling. it was just so cool to be a part of that project. even as a worker bee. point was that the seimens putty we used was unbelievable. and i think like $2800 a pail. something stupid like that. but unbelievably easy to make. a coworker there worked for seimens and his job there was making the putty. navy wouldnt let us make it though, they funny that way. was basically peanut butter with hysol, 8084 and a couple other things mixed under vacuum??? i shoulda payed attention, or at least stole a bunch of **** when obama closed the yard down. truck load after truckload of materials went to the landfill

A buddy of mine used seacast for transom and stringers on a little cimmeron bass boat...

He had a little left over and poured up a test sample n also another buddy used a little to fill a void in a rotten 4x6 stringer in his 26' cruiser... He didn't even scoop out rot, just sopped up standing water w a towel dumped the seacast in the hole....

When he closed the hatch the pneumatic strut stuck into it....

Later it was a nightmare trying to get the hatch back open and we never did manage to get the end of the strut out of the hardened seacast... It just wasn't worth the blood sweat and tears of trying to cut, grind, and break that stuff.

"......Seacast tm uses chopped reinforcement recycled fiberglass where others use ceramic spheres. In comparison fiberglass strands provide superior tensile strength better than ceramic spheres. Pound for pound, we dropped a 20 lb. weight from 10 feet creating 200 ft lbs of force. The difference is we dropped it once on the competition and they split and broke on the first drop. We dropped it 20 times on the Seacast tm, which resulted in just minor cosmetic damage."

EDIT:
Btw while 200 ft/lbs sounds impressive... I figured the force of impact for their test at 60759 lbs of pressure at assuming very little (.001 meters) compression upon impact...
