    Warning lights on dash.

    Looks like a “four winns VDO dash” you can google that and look at the CDI website for troubleshooting. And yes they can be trouble. Don’t know if they still do, but 4winns used to sell a new dash that plugged right in. That’s how the dealership I worked for handled this problem.

    2010 350 Mag MPI bravo 3 gaurdian mode issue. 5% power

    Where did you find the code 61 definition? Guardian at 5% is telling you it’s a critical fault. That’s a forced idle situation. My experience has been that it’s common for DTS faults to be the cause of forced idle. Something this critical will set at least one fault, maybe multiple faults...

    Axius repair on used boat Cobalt 303

    If you buy G3, you might still need the dealer numbers. Yes, all of Mercury Marine is down. Nothing online works and as of yesterday, no one seems to know when it will be fixed. I don’t know why it would work on the starboard. The starboard engine is the “master” engine. The port engine is the...

    Axius repair on used boat Cobalt 303

    I’ll try to answer your questions, but I should tell you I don’t have a lot of experience with G3. It came out many years after I had become MerCruiser master certified and I rarely used it in the field. Most of my time spent with it was in the classroom. The dealership I worked for back then...

    Options/Tools for CEL/DTC on Volvo Penta EFI

    You don’t say exactly what engine you have, so this is just general information. Easy connect will read some codes, but not all. It wasn’t designed as a diagnostic tool, it’s main purpose is to do what you already have plus if you want, you can share the data with a Volvo dealer. Rinda...

    2004 5.0 OSI-EF not going over 3000 RPM

    Probably not. Do you have two gas tanks or just one? Some twin engine setups will set Engine Protection Mode in both engines if one goes into it, if your boat has the master/slave cable installed. But you will usually get a warning horn if Engine Protection Mode is engaged. Do you get the 2...

    First start of season, how long for water from impeller?

    Yes, this. When you prefilled the system you probably didn't get much water in the block because the thermostat was closed. Getting the RPMs up to 1500-2000 helps speed things up and is important for those that have an engine mounted raw water pump (you don't, yours is in the drive).

    Axius repair on used boat Cobalt 303

    Oh Ya, I'm pretty sure that's probably the only option. But the people there at tech support who have access to the needed information won't talk to the consumer. They will only talk to someone who has a CDS G3 and the only people allowed to have G3 is a dealership tech. silver_power won't be...

    Axius repair on used boat Cobalt 303

    If the engine is in guardian it will set a fault code. Because Diacom didn’t show a code means that most likely it was a Axius code. Diacom isn’t very good with Axius. This is why Mercury G3 is needed and where G3 is connected is also important. When troubleshooting Axius plugging into the...

    I'm sorry but I can't seem to understand what you have posted here. Maybe I'm looking at the wrong manual but when you say ---- "There is also no co nection between D pin(TVM connector) with A1 pin." When I look at pin A1 at the PCM connector it's the "wake up power" that comes from the key...
