I am installing a Floscan, Twinscan GPH and Tachometer in my boat. Floscan suggested a GPH that maxes at 16+ GPH per engine and a tachometer that maxes at 8000. Does anyone have first hand knowledge if these are correct? My other options are GPH at 24 and Tach at 6000. Thanks

What engine(s) are you running on the boat? A 225-250 horsepower single engine on that boat will burn around 25 gallons per hour at full throttle. Some of the direct injection motors or four strokes will burn a little closer to 20 gallons per hour at full throttle.

So, I would choose a model that will read fuel flow rates in excess of the maximum fuel consumption of any type or engine combination that is possible on the boat.

The tach will also depend on the motor you are running. My 250 EFI runs at 5800 maximium RPM's and has a 6000 RPM tachometer on the boat. I think some of the big four strokes are running closer to 6000 RPM max so the 8000 RPM would be needed.

I am an idiot. Obviously that is important. I am running twim Mercury 150 EFI's, Saltwater series (not Optimax).

Here is a link to the performance results of the current 240 Outrage Model. They test this boat with a wide variety of engine combinations. One of the reports are the boat rigged with twin 150 horsepower Mercury Optimax. I know it is not the same boat and motors but I would think for purposes of estimating maximum fuel consumption the reports are useful.

Fuel consumption with this set up is thirty gallons per hour total or about fifteen gallons per hour per engine at wide open throttle. Looks like the sixteen+ gallon per hour and the 8000 RPM tach would work for your set up.

I would think you would want the Floscan model that has the ability to read the maximum gallons per hour and maximum RPMs of your motors.

That is exactly what I was looking for. Thanks.

Just a note for you to compare. My former 23' 1998 Conquest with Twin EFI Mercs burned 6-7GPH per motor at 3200 RPM. This was a 24mph cruise. Around 4000rpm this increased to 8gph per motor.
