Saddle Tanks or Standard 23 gallon tanks

[thataway]

The cleats with straps may well work. See how the new tanks fit--and what will be necessary. I don't like the brackets, since they are subject to corrosion and leakage into the hull core. You need to check the screw holes, and get any moist core/rot out, before putting the new tanks in place.

When you slide the tanks in place, then outline on the floor with a marking crayon the outline, and see what will be necessary. Many of the boats use these tanks and secure with cleats and some also use straps.
