If you suspect the control board on your Kohler genny, take it out and send it to these guys - https://www.flightsystems.com/. I did and was very impressed with their speed and acumen in helping me troubleshoot my problem. They'll test the board and repair if necessary. In my case there was...
Generally in vehicles - cars, boats, airplanes, etc - fuses are used to protect the wires, not the appliances. Depending on the wire type, they can tolerate an over-current fault for a short time (on the order of seconds or more) while they heat up to their maximum temperature rating...
Belt AND Suspenders? If it comes from the factory that way, I'd be interested in what their engineering minds have to say. I'm not sure about the 'wrong wiring' scenario ... fuses take too long to blow - the damage will be done before the fuse "opens" the circuit.
It works via BlueTooth with or without the hard-wired NEMA 2K interface. All of the MEFI3 parameters are displayed on your phone. I'm not a paid troll, just a happy, satisfied user.
Look into the Fox Marine MEFI3 gateway - it's magic. In addition to providing a NEMA 2K hard-wire interface to your compatible NEMA 2K chart/plotter it "plays" on your phone via bluetooth ... just get the app.
Wait ... what? What's this 'base timing mode' thing all about? What happens if you don't do the jumper wire thing?
I'm not having any problems with my GXi-A - just trying to understand.
I acknowledge that there may still be some water remaining, but when I pull the hoses and remove the plugs all I typically see is PINK coming out. If there is water remaining, it ain't much and it's in a place that has plenty room to expand when it freezes without hurting anything.
The -50 PINK stuff contains ethanol and propylene glycol. I run the engine on fresh water (muffs) until it comes up to temp - thermostat opens. Then I put 4-5 gallons of PINK in a bucket the hook to bucket up to my muffs and run the engine (Volvo-Penta 5.7) until I see PINK coming out the...
RE: ... top speed ... - I've got a 26' Cruiser with a VP 5.7GXi (the 320 hp version of the 5.7Gi ) running an F3 SS prop. It'll do 40+ mph at WOT with a couple people onboard. I concur with the "normal" operating parameters discussed in this thread. I've only had my boat (a 2001 w/ less than...
The Fox gateway allows you to read any/all sensors that the ECM uses to control the fuel injection. It depends on which generation of ECM/MEFI you have as to whether or not oil pressure will be included. On my older MEFI-3, oil pressure is not included in the standard MEFI-3 parameters. (Fox...
Do yourself a favor and get a code reader. I put a Fox Marine gateway on my 2001 5.7GXi-A and now have access to all the MEFI3 parameters in real-time on my phone. One way, but not the only way, to get to diagnostic stuff need top troubleshoot your problem.
I have a 2001 5.7 GXi-A w/ a MEFI 3 ECM. Suggest that you look into the Fox Marine NEMA 2K gateway - it's like magic! If you don't already have a NEMA 2K backbone on your boat, you'll need to install it ... <$100. Then you hook up the Fox Gateway to the ECM diagnostic port (OBD) then connect...
Recently had a chance to compare some performance data (F3 SS vs F5 Alum) DuoProps on my 26' 7000lb cruiser. To recap - My 5.7GXi DP-SM 1.95 has F3 SS props. I found a reconditioned set of D5 Aluminum on MarketPlace for $300. While VP does not recommend a D5 aluminum for my GXi (only 280 hp GSi...
My steering gets "loose" occasionally - lots of free-play or dead-band around center. From my reading (mostly internet blather) I've concluded that these hydraulic marinized power steering systems tend to get air in the hydraulic lines. Easy enough to fix - at slow/idle speeds just do a series...
