Brian; each unit shows total gallons consumed per engine so you need to multiply by 2 for total consumption. Make sure you hit reset on both units every time you fill up the tank. I was told to disregard the generator use in the calculations. Jose Jaen "Blue Chip" 1993 33FBC Miami FL

You guys have me confused. On my Floscan 9000 series gas.I have one gauge at the helm that reads both engines.The gph is read per engine so that figure needs to be doubled for total gph burned.However the totalizer (aka gas gauge or gallons used) is already combined so you do not double that figure. Are you saying that the 9500 series diesel has 2 separate gauges at the helm (1 for each engine)? As far as the generator, it only burns about 1/2 gph so you just have to deduct that yourself which at best is usually 5 gallons per tank and i would hope to not ever run that close to empty anyway.

What do you mean 5 gallons per tank? There's only 1 tank. Regards, Doug L. 1986 33 Bertram FBC Queen Elizabeth Marblehead, MA [img]http://www.bertram33.com/photogallery/p ... sabeth.jpg[/img]

Uh Doug !!!! per tank of fuel, per 300 gallons burned ...aka 30 gphx10 hours = 300 gallons burned...so 10 hours x 1/2gph = 5 gph on the genny You mean that second tank i have been filling is the water tank?

Gotcha. Regards, Doug L. 1986 33 Bertram FBC Queen Elizabeth Marblehead, MA [img]http://www.bertram33.com/photogallery/p ... sabeth.jpg[/img]

Yes Tim, the 9500 series diesel comes with 2 separate gauges with which you replace the old ones. The MPG feature is only displayed in one. Jose Jaen "Blue Chip" 1993 33FBC Miami FL

Ordered the Flo Scans this weekend, got the same as Frank for about 628.00. They were on sale at Defender. Can't wait to get them in!! Bill 33 FBC Ipswich, Ma. [img]http://www.bertram33.com/photogallery/p ... a_Rose.jpg[/img]

I just started installing my last night. I got the Tach in and wired about an hour past Dark. I didn't checke it out becuase the extra wires are just hanging wiating to be connected to the FuelMeter and GPS. So far I like the look of the Twinscan, though I went with white and they stick out like a sore thumb on my black panel. I just thought the white looked more readable than the black. I'll post an update when i install the fuel flow meters and gauge, probably this weekend, between T-Ball games and pratice. br, JohnD

Keep the updates coming John, write down a schematic for me, I'll be doing mine next! Do you have the Aeroquip fuel hoses? Where are you mounting the fuel/water seperator before the sensor? The directions look confusing because they give you every set up for every model, for every engine type! Bill 33 FBC Ipswich, Ma. [img]http://www.bertram33.com/photogallery/p ... a_Rose.jpg[/img]

Well I worked some more on Sunday when we got an unexpected break from the rain. I'm glad I got the time, it's going slower than I thought. I’ve not got about 13hrs in the project working by myself and am ready to do one last check of everything and then start the motors and test it out. This and closing up the access panels and clean up will probably take another 2-4 hours. The tach’s were installed the other day and didn’t take too long. I re-used existing wiring so that made it easier. I did find a couple of 2-wire cables which went no where so I removed them. Here’s what I did. 1) I installed the tach’s first, figured they were the easiest. It took a little time to get everything opened up and remove a couple of old cables (2-wire type) which weren’t in use anymore. 2) Based on some comments from the Consumers Marine tech when I bought the floscans, I ran a 4-wire cable (16/4) from the bridge to the engine room. I ran 2 of the wires to each sensor then grounded the sensor to the engine block. 3) Installed the fuel flow gauge, double and triple checking all the wire connections. 4) Then I ran the plumbing, I was able to re-use the section of fuel hose from the filter to the flow sensor, then installed a new piece of hose between the flow sensor and the motor. I was pleasantly surprised that very little fuel dripped when I first removed the fuel hose from the motor. 5) The only thing left to do is to double check the fuel line connections and then test the motors for fuel leaks and the tach’s and flow meter. Tips/Lessons I lost a good amount of time to stripping the jacket off 6-8ft of the trunk cable which ran to the fly bridge. It was also a little tough locating the 16/4 wire. In hind sight, it would have been simpler to just run 2 3-wire cables, one to each unit. Another lesson was to use the heat-shrink but connecters instead of the ones provided. Though it takes a little more heat to shrink the but connecters, definitely less hassle. Trick someone smaller and younger to do the plumbing of the fuel lines [:D] The starboard motor was the worst since the fuel line mounted on the outboard side of the motor. I was able to access it from the cockpit laying across the exhaust hoses, on top of the stuffing boxes. The port motor was a little easier since the fuel line mounted on the inboard side, there still wasn’t much room to work and hard to get comfortable. Sources I used. - for the 16/4 wire: http://bestboatwire.com/ - for heat-shrink connectors: http://www.delcity.net/ I’ll post results of the testing in a couple of days, it’s Monday now and back to work! Cheers, JohnD

Well Monday night I double checked everything and then tested the motors.... and nohting... no tach no gph??? Turns out I had about 3-4 of the crips that were bad and had to be redone. I guess the problem to be the heatshrink connectors need the wire to be pushed all the way in. Not that I didn't think I had, but when i re-stripped the wire a little longer and then crimped the connector It got everything working. Another mistake was to ground the sensor's to the motor, even though it said not to to it in the instructions (i didn't notice that in earlier readings). I re-wired the ground to a battery ground in the main breaker area and the GPH worked. The last things now are to wire in the GPS data and install the switches for the totalizer and mpg/sync. Also repalce all access panels which were removed. All in all not a bad project, just time consuming to be able to get to everything. If you can work with two people it would go a lot quicker. After about 2hrs work I'd fixed everything and had the Tach's working, with engine sync. Also, the GPH working, though there is some fluxuation at idle and when reving not in gear. If all goes well and weather cooperates I'll be giving them a test for real this weekend. -JohnD

Well done John...you will enjoyn the benefits of the floscan

Man you want those electrical connections to be right or they certainly will bite you in the ass later, always at the worst time. If you have any doubts about whether they are solid and hermetically sealed, then I suggest you R&R all connections, solder and heat-shrink every wire. If they're not sealed well now, when they do fail all your wires will be green inside and you'll be re-running the whole harness again in a few years Sean Burlingham "Island Time" 1987 Bertram 33 SF Melbourne, FL SBurlingham@cfl.rr.com

Thought I'd post an update. I ran the boat on Sat and Mon. this weekend both times about 1/2hr each way, on Sun just a short local run. Total fuel burn for the weekend 84 gal so I'm burning about 38-40 gal an hour at 3200 cruise (21mph). The flow scans tell me that the Port motor is burning 17-18gph while stb is only burning 14-15gal. I suspect its due to spark plugs and distributor points. I'm going to replace these and see what happens. I won't be able to check acuracy for a while since I plan to finish runing out last years gas be fueling with this year's ethanol-gas. Everything is wired and installed with the exception of the gps feed for mpg, haven't got around to that. It's a good reality check to see the gph gauges shoot up when you push those throtals forward. Hopefully after plugs and points the port motor will settle down and not be so thirsty. At least now I know what I didn't before. -JohnD

my port and starboard are never the exact same . usually i gallon apart
