when I did my straps...
First time:
for waterbox: two coming from the single hook way up front to those two inserts installed by eme that you have in your pics.
for tank: another two straps from the eme inserts crossed over the tank and to a hook that i mounted on the stator cover of my motor. I also glued a piece of 25mm padding to the bottom of the tank then glued the tank to the hull.
was kinda "hacked" all togther, but surprisingly everything stayed in there tight.
I got sick of the look of this and eventually water peeled up the padding, so i re did the whole thing.
2nd attempt:
for waterbox: two coming from the single hook way up front to those two inserts installed by eme that you have in your pics.
for tank: I epoxied 4 inserts that i bought from mcmaster car using west systems w/ 404 filler, then a layer of carbon (2 in x 2 in square pieces)
much much cleaner look and better results.
