Rochester Gauges 6580-00161 (6580-161) Fuel Gauge for Boston Whaler
The 6580-00161, also referred to as the 6580-161, from Rochester Gauges is a senior, fixed length model designed to fit the 70 and 140 gallon Florida Marine Tank inside many vintage Boston Whalers. This gauge is manufactured for us by special order and it comes as it was originally designed along with (4) mounting bolts and a Buna-N gasket. This gauge is available with the original aluminum bezel dial, P/N 5002S00062 (aka Dial No. 5-62) from the drop-down menu. TwinSite fuel sender dials are also available in 240-30 Ohms and 0-90 Ohms if you would like to transmit your fuel level to a remote instrument in your console dashboard. If you purchase a TwinSite sender dial and need a matching dash instrument we carry those as well.
IMPORTANT NOTE: Most vintage Boston Whalers have a fuel tank flange that is not threaded for the (4) 1⁄4"-28 x 9⁄16" mounting bolts. Instead, it requires the gauge to be mounted with longer fine thread bolts and matching nylon lock nuts. Because of this design, we have sourced the necessary parts and added the following optional bolt kits:
Bolt Kit BK-1 includes (4) 1/4"-28 x 7/8" bolts and (4) 1/4"-28 nylock nuts, with all parts being high-quality zinc plated steel.
Bolt Kit BK-1-SS includes (4) 1/4"-28 x 7/8" bolts and (4) 1/4"-28 nylock nuts, with all stainless steel parts.
The gasket that Rochester ships with 6500 series gauges is part number 0015-00004 and it is a flat ring gasket. We also offer another Rochester Gauges gasket that is precision cut to seal the underside of the gauge. This gasket is far more effective at sealing the tank while also keeping debris and moisture from getting trapped between the flange and gauge head, leading to premature corrosion. It is part number 0015-00079 and an image depicting this gasket alongside the standard ring gasket is in the gallery.
Please verify that your original gauge was a 6580-161 or contact us for assistance if you're uncertain.
