    2004 Johnson 150 Spark Advance Linkage Sticking

    Little update here and to bump the post. This model doesn't incorporate a timer base in the same way as the older models or adjacent crossflow models do. Optical sensor handles it on the that sensor support up top. Therefore, it looks like there is no reason to tear into the flywheel and...

    2004 Johnson 150 Spark Advance Linkage Sticking

    I've got an '04 Bombardier 150 with a sticky spark advance link. When coming off the throttle it likes to hang and not follow the throttle linkage back to it's home. Usually it'll stop just short of being fully released. Now traditionally on older models it sounded like the advance mechanism...

    Johnson 150 Bombardier Water Temp Sender Port

    I'm interested in putting a Water temp gauge on our 2 stroke outboard. We already have a water pressure gauge so this would be an additional line of defense. I've done some research and there isn't exactly a straight answer but it seems we have an unused water jacket plug on the port side...

    Johnson 150 Bombardier Vapor Separator

    Hope everyone is well, I made a post some months back that turned into a long thread with great information in waking our 2004 Bombardier up after its 3 year long sleep. Runs great now and many a trips have been planned because of it I thank you guys for that. Couple things I’m unsure about...

    Continuous Alarm before Startup

    Certainly threw us for a loop. We took the boat out and it ran great, better than before so they certainly fixed a few other issues it had. Spent quite a bit though so it would have been nice to not have had to track this issue down. Aw well, glad it was simple enough. Thanks a lot guys...

    Continuous Alarm before Startup

    When ordering the Switch I noticed an extra brass fitting in the diagram. I do not have the original part to compare obviously so what do you guys imagine it is for? Is it necessary? There are two options as well, and one is three times the price of the other. I went ahead and just added the...

    Continuous Alarm before Startup

    Sorry I probably wasn’t clear enough. The alarm never shut off when we started the motor. We only ran the engine for 10-15 seconds before shutting it off to be cautious since the alarm was still sounding. I found my answer today though. So, they didn’t actually replace the sender like the...

    Continuous Alarm before Startup

    Haha you beat me to it. Alright this will be the first thing I’ll check for failure. If that checks out, then I’ll try the stern drive gear level sensor. If that checks out I think it’s time to just have the mechanic remedy something he might have wired incorrectly. Certainly wanted to...

    Continuous Alarm before Startup

    Nevermind, I found the switch in a different subcategory on Marine Engine. PART#: 87-805605A 1

    Continuous Alarm before Startup

    My thoughts exactly. Since the oil pressure sender and gauge were faulty and replaced by the mechanic, logically the oil pressure switch wouldn’t be too far behind those components in terms of longevity and is likely faulty too. Marine Engine does not show any “oil pressure switch” for my...

    Continuous Alarm before Startup

    Are the gauge wires also tan and blue because both of the temperature probes for the overheating circuit had a tan with blue stripe wire.

    Continuous Alarm before Startup

    Thanks @Dieter , turns out its never as simple as one would hope. So fired her up today and the alarm stayed on while running for about 10-15 seconds. The first I have heard about this, but the oil pressure gauge was pinned at max last year so he had the mechanic look at it when it got...

    Continuous Alarm before Startup

    Yes I know. That is as long as those sensors and switches are not faulty and grounding out. Regardless the constant tone before startup is normal and all is well as long as it goes out after the engine is turning (oil pressure builds). Thanks guys for lending me your insight. I appreciate...

    Continuous Alarm before Startup

    So after another phone call with Mercury Marine and them telling me it’s not normal and should not be sounding a continuous alarm before startup, I asked for them to send over the engine Owners manual. Low and behold this is what I found: I even asked the tech rep to look at the manual to...

    Continuous Alarm before Startup

    It’s not allowing me to post a photo of the engine cover but I assure you it’s the MCM 5.0L V8 305 CID. Serial No: 0F429743. It is definitely carbureted.
