I have a brand new Fisherman 236 with a 115 gal fuel tank.
The Command Link Plus display never shows a fuel level between 95 and 115. It stays at FULL for a long time then
drops right to 80 or so. I watched it at the fuel dock: It started at 80, then went to 85, 90, 95 briefly, then FULL. I then added another
15 gal until it over flowed. CLP configured for 115 gal, ABYC sensor.
Another test: Filled the tank, reset the CLP engine statistics, went for joy ride, and came back to the same fuel
dock. Stats now read: Available 80, Used 21.8, Trip 54 miles, Ptrip 4.6 hrs. It took 23.8 gals to refill. Same fuel dock,
same gas pump, just me in the boat standing at the helm both times. Its like the float gauge thinks it is a 100 gal tank.
Explained this to dealer service manager, he said there is a fill limiter, and a whachamagigger, and its a float style, etc..
Bad answer, My lawn mower float gauge works fine, shouldn't my $100K boat tell me how much gas I have?
Anybody else's boat behave this way? Or is this a sloppy calibration job?
Anyone done the Single or Multipoint calibration described in the manual?
(I saw the tank when the boat was being built. Its basically a rectangular box with a slight V at the bottom,
so a float sender should be fairly linear except near empty where I never plan to go)
Also, can I really put 115 gal in a 115 gal tank or is there some Limiter to provide expansion room that the dealer referred too?
Emptying the tank to do the calibration seems like a real pain, but I don't trust the dealer to do it right.
Independent of the fuel gauge,
in the example above, the "Used" fuel as measured by the engine's flow sensor differs by the amount
of fuel I refilled it with by about 10%. I reset it at every fill up and get about the same 10% difference each time.
I saw another post where the guy's numbers differed by about 1%, any idea what accuracy to expect?
I saw a menu item for adjusting the flow calibration, should I do this?
I see where most folks use the engine's consumption number over the float gauge. I get it.
All experience and/or guidance appreciated!! (My first boat was an 18' Sea Ray 3.0L Merc , very simple.
This is a huge step up for me to the "big" GW, far more complicated . . . and fun.)
