Seacast Transom Repair

[mauryc]

25'' LONG x 1/2'', 9/16'', 5/8'' WOOD BIT SET

ITEM 33450-3VGA

As far as the quantity, I'm not knocking your calcs, but if your transom is as thick as mine, there is no way you'll use 15 gallons unless you spill a third on the floor. I had calculated 16-17 for mine but only ended up using about 14. I guarantee my transom has more surface area than yours (if you have the older style transom). On the other hand, you'd hate to start the pour and come up short. If I recall correctly, I ended up calculating about 3900 cubic inches of void using 1.75 inch thickness.
