I am rebuilding my pontoo boat & haev no gauges at present for my 1987 Johnson 70 hp 3 cylinder engine. I've been looking at ebay & craigslist & I am lost as to what I actually need as far as name brand & type of gauge. I have no idea what gauges will work/not work with my engine.
I am wanting a a tach (what rpm is needed), a gas gauge, trim, volt & a 35 mph speedometer. I realize everything I mentioned above is pretty much standard except for the tachometer. How many poles is required for my engine & what type of trim gauge will work? Do the gauges have to be strickly for a Johnson outboard or are universal gauges available? Any help would really be appreciated as I am ready to order the gauges & get this pontoon in the water. Thanks
