What kinds of engine instruments are on your boat?

i use and calibrated my fuel flow gage(navman)and love the thing. I have friends (hard to believe I know) that never even put fuel gages back in their boats when replacing tanks or their gages go bad. The standard fuel gages are notoriously innacurate. When you calibrate one though, I think it is neccesary if you have a fairly large tank- i.e.> 25 gallons, to calibrate it using the largest amount of gas/number as possible (gallons at refill vrs stated # on meter). Trim Gage would also be nice- (trim Tabs)- i have seen the smartpack system on my buds new 350/325 merc i/o/ coupled with the garmin bottom machine and it is sweet. I like to track engine hours as well for oil changes, thats about all I pay close attention too- The navman/tach/motor water temp (and charging system and track of the boat while running set-up on the plotter)
