    Volvo penta 5.7 GXI TBI Scanner

    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.

    Volvo penta 5.7 GXI TBI Scanner

    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.

    Setting Timing on a 2002 VP5.7GXI-A

    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.

    Does the antifreeze you use really matter?

    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.

    Does the antifreeze you use really matter?

    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...

    Checking out a 24' Four Winns with a 5.7 Volvo Penta motor

    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...

    2003 5.7 gxi Volvo penta seems to go into safe mode with no alarm

    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...

    2003 5.7 gxi Volvo penta seems to go into safe mode with no alarm

    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.

    Volvo Penta OBD port

    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...

    Where to Find Kohler 5E Generator Motor Mount / Fuel Pump bracket

    Check eBay - lots of 5E units from "runs perfectly" to "parts only" to be found there.

    Sacrificial Aluminum Prop

    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...

    New to Volvo family

    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...

    Knock Sensor

    One picture is worth a 1000 words - Yep, that's the fitting - very helpful. However, on my installation the knock sensor and plug were reversed. There is an engine mount or wire bundle that prevents the orientation as shown ... so, they stuck the sensor on the end and the plug at the 90-degree...

    Knock Sensor

    I've got a 5.7GXi-A. The knock sensor screws into a brass fitting (a tee) that extends from the block drain on the starboard side. The sensor screws into the tee such that it is parallel with the block. The 90-degree part of the tee is just a threaded plug that allows the block to be drained...

    Sacrificial Aluminum Prop

    Considering that I don't have that much invested in the aluminum props, I'll give the D5 a try carefully watching for signs that I might be overloading the engine. If things don't work out as I hope, I guess I could have them re-pitched? I understand that it is acceptable to re-pitch up to +/-...

    Sacrificial Aluminum Prop

    Help me understand in technical and quantifiable terms how to identify when my engine is "lugging". If I'm going up a hill in my manual transmission car and I hear pinging/knocking, I know my engine is lugging and I need to down-shift. A little different in a boat. In my boat I can monitor...

    Sacrificial Aluminum Prop

    Got a smokin' deal on a reconditioned set of D5 (Aluminum) duoprops for my VP 5.7GXi/1:1.95 firmly attached to my 6500lb cruiser. Current prop is F3 (Stainless). I have no issues with the performance of the F3 - snappy to get on plane, tops out at 40+ mph and cruises comfortably at 20-25 @...

    Bellows Water Detector - Retrofit?

    I'll get some pics when I can. Here's the story on my boat - bellows and gimbal bearing last changed in 2011 @ 200 hrs. From 2011 to 2018 accumulated another 100 hrs (15 hrs per year!). The boat was only used on Lake Powell - 4-5 month seasons. When not at Powell, she was on a trailer in the...

    Bellows Water Detector - Retrofit?

    I'm pretty handy mechanically but I've never pulled the drive. It's my first I/O and I've only owned it for one season - it worked great and don't suspect any issues. My local VP shop said to expect $2000 to $2500 to pull the drive and replace gimbal bearing and bellows. Of course, if I ask...

    Bellows Water Detector - Retrofit?

    Great Scott! Your wisdom is on full display here. I watched this Ted's Marine video that shows the WIB sensor buried on the transom assembly of the OceanX drives ... it's a nightmare if that thing ever fails and needs to be replaced. I will up my game when it comes to regular, external...
