My 04 Speedster left Tach went dead. I know it's the Tach because when I put the wires onto the right Tach that one works fine. The Tach part number is 204470777. I found a new Seadoo Tach at Greatlakesskipper.com for only $69 with a part #204470321. It looks just like mine but with a white face instead of blue and the back has a 6 prong female receptical. Mine has wires that bolt right to the back. Anyone know how I should wire to the 6 prong female receptical Tach. Which colors wires go where? Sure beats $250. Here is a link to the $69 Tach http://greatlakesskipper.com/produc...evinrude-omc-sea-doo-jet-boat-tachometer.html There is all kinds of cool stuf there.
