Re: What kinds of engine instruments are on your b
a vacuum guage is a complete waste of space on a boat, the only time it will ever read vacuum is when your idleing, or when you back off the throttle, you're under enough load the rest of the time, that a vacuum guage will read very little difference, if any, when plumbed to manifold vacuum. Best guage to get is a reliable tach, and check it against an even more reliable tach, check all you guages at normanl operating range against known measuring devices. Most marine gauges read somewher close, never accurate. I've check 6 new temp gauges right out of a box, found them to be as far as 25 degress off, no two of them were the same. Buy a good fuel flow meter and calibrate it, they are close sometimes, but whats the use if you don't know if its right. Be carefull with the smart craft, that is a calculated fuel flow, not a measured fuel flow, and the fuel level is only as accurate as who calibrated the smartcraft when it was installed
