Check with your local BRP dlr. He'll have the specs for what tach you need.

iboats sells them as do many stores http://www.iboats.com/Boat-Parts-Ac...271818--submit.Search--submit.x.0--submit.y.0 You only need a 7000 rpm tach.

There will be a gray wire inside your control box which is the tach feed. You "might" actually have a small plug in exposed on your control box . The tach wiring is very simple. It gets 3 wires....... positive, negative and gray wire. The only other item is to set the pole switch on the back of the tach to the proper setting.
