My current pontoon (96) and previous (79) have no gauges at all. I have a fish locator that can tell me my speed but I wanted at a minimum a tach & warning lights.
In order to make this work I first had to replace the electrical cable that runs from the console to the outboard. The PO chopped all the "unnecessary" connectors off when the carpet was replaced.
Once I finished that I then had to bore a 3-3/8" hole in the dash for the tach. Why do they make them an odd size like that? I could borrow a 3-1/4" or 3-1/2” hole saw but instead I used an adjustable woodworking "flycutter". I went VERY slow and carefully so it wouldn't skitter around or smack my knuckles and the hole came out perfect.
I think I also need tilt/trim & volt gauges.
Now that I know my speed AND rpms I see I'm almost 1000 rpm under max at WOT. Now I have to read through all the "prop selection" threads!

Re: Installing a tach
I bought it off eBay, $100 new but no box or instructions. It's a Teleflex "Lido" for Johnson/Evinrude with System Check lights. Mod. 64477F.
I'm pretty sure Sierra 64477FP is the same gauge.

Re: Installing a tach
That’s a good looking gauge background. Is that leftover flooring? It goes well with the gauge.
Re: Installing a tach
That's the original dash panel. Supposed to look like fiberglass I guess.
