I want to outfit my boat with any gauges that might notify me of trouble - any ideas?<br /><br />I currently have a Tach, Speedo, Gas, Trim. thinking about getting a Volt and a Hour meter.
Yes, a fuel flow guage is a nice thing to add. Have a look at the Navman series. I have a Navman Fuel 3100 myself (interfaced to a GPS Chart plotter). <br /> http://www.navman.com/marine/products/fuel/index.html <br /><br />Hour meter is good also so You know when to service the engine.
Depending on where you buy them, the volt meter and hour meter should each set you back about $20-$30, with the temp going a little higher.<br /><br />The fuel flow guage is nice, but it'll set you back at least $150.<br /><br />Your profile states you're running a 200HP Evinrude on a 23/24' Hydra Sport, so the fuel flow guage might be fun to watch!
