MJ - It's close to 100lbs . . . I'm going to hang it up soon and weigh the bracket. If my math is correct . . . the bracket will provide roughly 400lbs of positive flotation.

sound good!! I wonder what mine has for flotation??

How do you do the math on that??

you can calculate the volume figure, 1 cubic foot = 7.48 US gals. @8.25 lb per gal. or...If it is easy to drain, you could fill it with water one gal at a time and measure its displacement.

I just calculated the volume of the bracket in cubic feet
then multiplied by 62.4lb

and subtracted the weight of the the bracket.
(not sure if I should be using the submerged weight 100 x .33 = 33lbs) but it works out to be around 400lbs.

I cheated and went to Stainless Marine site and they say I have 315 pounds of flotation. ;)

LOL, Cheating is ok M.J., it still gets the job done. ;D

I got the bracket primed this weekend! Just gotta remove the old motor, plug the hole, sand, paint, bolt on, rig, and go!! Only a few weeks till Salmon Season. :)

Do ya install the bracket on the transom, then hang the motor, THEN add the flotation?...

hang the bracket first, then add motor, the air in the bracket is the floation, there is nothing to add.
