    Bizarre IAC reading

    All the boat info is in my signature, Yes it is, looks like there is someone who should feel stupid --- me? --- sorry. At my age you would think I should know better. Or maybe that’s the problem? #3. yes, if it hasn’t been repropped. 25’ SSI w/6.2 should be about 50-55 MPH? Probably #1. Also...

    Bizarre IAC reading

    You didn’t post a serial number or even a model number, but I see what looks like an ECM 555 in one of the pictures so I’ll take a guess. The MerCruiser PWM (pulse width modulatio) IAC is a great source of revenue for shops. I’m not sure why they cause so much trouble in marine applications...

    Malfunction indicator Light constant on

    And I don’t want you to think I’m bad mouthing your Techmate. They are a great tool for certain situations. I will sometimes use one first for things like a MIL or check engine light. Boot time is very fast! And the screen is much easier to read in the sun. But people should know it’s...

    Malfunction indicator Light constant on

    I would like to say Thank you for your service to our country. I’m sorry you have a lack of good dealers in your area. Volvo Penta does not have certified technicians. They grade their techs on levels. Higher levels will unlock more features of Vodia which Volvo Penta sells that a “good”...

    Malfunction indicator Light constant on

    If the light doesn't go off after 3 trips there is a problem. Nice picture of the dogs. Easy to tell which on is on lookout duty. But it might have been helpful to post a pic of the engine status panel with the light on. There should be two lights in it and they both can have somewhat different...

    No Trailer and Trim Up

    There were two 3 button switch's. Early models you pushed just one button to trailer. The later required you to push two buttons at the same time to trailer. You are correct that the switch by the bell housing should be normally closed and open the circuit when the bell housing hits it. If I...

    Volvo Penta stiff steering

    This is very common, each boat can be a little different. Has to do with what helm and steering rack is on the boat.

    Volvo Penta stiff steering

    With the steering cable disconnected at the cylinder, the steering wheel should turn easily. Like one finger easy. Now disconnect the steering arm at the rack. Drive should move easily. These are just two things to try. You haven't told us what Volvo Penta transom plate you have. Serial number...

    Outboard MARINER 75 ELPTO wont start

    The yellow/red wire should go from key switch into the throttle and then out of the throttle to engine harness. Shouldn't go the gauges. Suggest you go to the engine and find the main harness. It will be by the starter and starter solenoid. You may need to remove the battery cables to get to it...

    Outboard MARINER 75 ELPTO wont start

    Ya, red to black at the key switch sure should have let the smoke out of the fuse. Not sure why it didn't, maybe has very high resistance somewhere. Still that doesn't explain the chirping.

    Outboard MARINER 75 ELPTO wont start

    I mean the two wires that DON"T go to the shifter. One of them will go to the key switch and the other will go back to the motor. The yellow/red wires coming out of the shifter usually have a quick disconnect somewhere in them.
