Re: Belly tank on starchief?
My Sylvan/Smokercraft is very similar and I bought an New/old stock Moeller 28 gal much like the 032529 29 gal.
With the 3% expantion the tank is going to be just a bit wide for the 24 inches between my "stringers" Height should be fine, the filler neck and such make up the most of it, fitting in by the stern bilge access and,,,,, To get the fit on the width,, I am going to have to move the "stringers" "joists", whatever you want to call them, away from each other an inch or two. This will bring the deck up just a bit from the bottom of the hull.
To get one in you are pretty much going to have to rip the deck up anyway, so the minor mods should not be a big deal.
What I am still pondering is how best to "bed it" ( don't want that plastic rubbing on the aluminum) and "strap it in" fore-aft.
