I can’t say just "any" gauge but certainly the "standard 2" fuel gauge and a "universal" Speedometer will fit the holes. I would caution that almost all of the fuel gauges don’t work like you would expect. Not like your car. It’s best to be sitting still when you try to figure how much you have. They do tend to read at the full and near empty range, the rest is just a guess. Then the Pitot tube type speedometer is often inaccurate, and/or don’t work at all.
You might try your local Boat Dealer or go on line to find something. In these cases. there is a bar across the back of the gauge that holds it in place. a ground wire and a dash- light wire (blue). The fuel gauge has a pinkish wire that you attach to the "S" terminal and a purple (ign) wire to the "I" terminal. The Spedometer only has a plastic tube that pushes on .
