Adding guages.

[66KingFisher]

Ok, one of the things missing on the Tracker boat we purchased was any sort of guage in the dash......I was surprised there wasn't even a tach on this model..lol....the saleman said they could install one for $175...$75 of that was the tach. I figured heck, I can install a tach, and surely I can find one cheaper then $75....but after searching the web last night I was surprised to find all the marine tachometers I saw seem to be priced between $75-$95. I originally thought I'd use an automotive tach, but since our motor turned out to be a 3 cylinder, I can't do that either....lol. Any of you guys ever install a tach or speedo on your boats?.....Its not a big deal is it?

Also the shop guy that gave us a brief rundown of the boat techy stuff before they hooked the boat to our truck, kept talking about maintenance based on "hours on the engine", but there isn't an hour counter on them so what do you guys do regarding maintenance....go by time on the water or hours of engine running or just every few months or every season or what?....Should we think about adding some type of counter that keeps us with how long the engine is ran?
