    1985 Mercury Black Max oil alarm >3k RPM

    Worked great yesterday, looks like the replacement alarm module was the problem all along.

    1985 Mercury Black Max oil alarm >3k RPM

    All the ignition stuff tested good with DVA. Made a jumper to give that wire I mentioned 12v like it's supposed to have and no alarm during testing. Hopefully that's the fix. For whatever reason, today it's idling a lot higher, 12-1300rpm instead of like 800. Gonna take it out on the lake...

    1985 Mercury Black Max oil alarm >3k RPM

    Ok thanks. And yeah the oil injection stuff is what I've been focused on and looked like the same for many years. For the charging system on this motor, should I be seeing >14v at the battery when it's running or will it just be a bit over 12 since it's the 16a not the newer 40amp system...

    Yeah, looking at the factory parts diagram for the serial number range that covers this motor, it lists 3 potential options. Not sure which one this is and what I should be testing for. I agree it's looking less like this is the problem but now I have the DVA so want to test it either way. If...

    I've been using a factory service manual I found online for 1992+ motors since like 95% of things are the same as this motor, but I've noticed when looking at specific part number versions, the stator is one of the things that isn't the same. My manual references a 40 amp stator, and this motor...

    1985 Mercury Black Max oil alarm >3k RPM

    One thing I forgot to mention, I'm 99% sure it checked out ok when installed but last time I checked the white wire on the alarm module that's supposed to be 12v was 5v, so I guess the alarm module could be an issue as well. I've been thinking it will end up being the high speed side of the...

    1985 Mercury Black Max oil alarm >3k RPM

    Hi all. Working on a ~1985 Mercury Black Max 175 that was in storage for 12 years. I’m told by the owner that it was completely overhauled shortly before going into storage, and he wants to keep everything as is as much as possible. I know deleting the oil injection and running premix is...
