    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...

    Axius repair on used boat Cobalt 303

    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...

    Axius repair on used boat Cobalt 303

    Yes, this looks like what’s in the PCM 555 manual. For a full wiring diagram on this engine and its interface with Axius you will need a wiring diagram binder that MerCruiser sells. It is a very nice book, large pages that are laminated and full color. your mechanic should have access to it.

    Axius repair on used boat Cobalt 303

    I took a quick look, this boat has a history of issues and a lot of service bulletins. Is your mechanic aware of all this history? It looks like "white glove" might not have been completed? And that S.B. has been revised 2 times since the last record of service. Did your mechanic change the city...

    Volvo Penta 280 Drive Shaft Nut Clearance

    I worked for 4 different Volvo dealers here in Minnesota. Only one of them stocked all these shims. They are long gone. 2 are still in business. Have you tried the dealer locator on Volvo’s website?

    Volvo Penta 280 Drive Shaft Nut Clearance

    What a long strange trip it’s been. Sorry but that seems to fit here. I have to believe the dealer just had some mismarked shims and you will be able to get the right ones. If you can’t If the bearing you’re shimming has been spun under load at least once—go loose. If it’s a brand new...
