On a 190 MONTAUK I believe there is an instrument panel escutcheon which will tend to constrain your choice of the number of additional gauges which can be installed into the existing escutcheon. You should give some consideration to the question of what additional gauge is likely to be the most important and deserves to occupy a prominent place. As a general rule, an hour meter does not require continual observation, so it may not be the best candidate to take up the scarce space on the instrument panel. Any alternative location where the hour meter can easily be observed when desired is good. For example, I have seen hour meters mounted inside the helm console, or even under the cowling of a motor.You can also install the hour meter on the console outside of the instrument panel escutcheon. Before drilling any holes, make careful measurements and check to see what equipment is mounted inside the console in that area.
If the meter will be generally visible, to keep the appearance of the boat consistent, I would get an hour meter that matches the size, color, and style of your existing gauges. Usually these are 2-inch round gauges with a black bezel.
Hour meters are generally all of the same type: they're electrically operated and have an odometer style display of digits. There is not much difference among brands as far as I can determine. I'd go for matching appearance more than a particular brand.
