For selecting a bow trim gauge, what information should I have before contacting a distributor or sales rep?

1. Diameter of the opening the instrument will be mounted in
2. Do you require lighting in the instrument
3. Are you running a 12V or a 24V system (voltage adapters are available)
4. What type of sender do you have (i.e. OMC, MERC)

If you wish to match the style of existing instruments you should also have the following:

1. If your current instruments are a Stewart Warner line, which line (Seaworthy, Heavy Duty, etc) (see the Stewart Warner Products page page for the product lines)
2. Bezel color wanted (black, blue, teal, etc)
3. Dial face and graphics (black dial, white numbers, SAE symbols, etc)
4. Pointer type and color (i.e. red with black hub)
