for those boats already equipped with an eqaualizing tube joining the two
tanks; how about cutting into that pipe and diverting it to one of those
"contractor" style refueling pumps they have on a drum in the back of
their pick up trucks.
These pumps can be had in 12VDC 24VDC and 120VAC
The big pipe will allow faster flow and installation of a big filter with
a turbine water separator. The return from the pump can be diverted to
either tank. This allows for taking dirty fuel and depositing in a clean
tank or simply recirculating it.
Admittedly these are not "marine" grade. They are rugged industrial units.
They are ignition proof to meet UL fuel pumping standards.

When I worked for a power utility we used such a system to "polish" the
transformer oil during the once a year downtime maintenance.  We pumped
and filtered 2000 gallons in less than a day shift. Pump and filter
mounted on one of those little hand trucks. The filter canister was 24"
tall and 8" diameter. 100% water separation since even the tiniest bit
would cause the energized transformer to blow up if water was present.
