...it's lonely. I'm married. ;D LOL
Just goofing off. Now to the topic, which is my '87 175hp...
To refresh, I have little leaks around the engine I'm trying to get rid of, and the alarm goes off after about a minute. If you shutdown and start again, it still takes a minute to go on. I replaced the t-stats and cover gaskets, which eliminated the leaks there. The alarm still goes off. I paid a little better attention, and the alarm is an intermittent, steady pulse. I go to the web and read all about it. I understand a constant alarm is overheat, while a pulse is low oil. The VRO was disconnected on this motor, so I read up on the alarm differences. I checked the procedure to disconnect the VRO system and voila, my VRO pump harness was still connected. Gotta' disconnect it or the alarm goes off. Disconnect, alarm gone...cool. It's on the muffs for five minutes and is running nicely. I can touch the power head barehanded. Shut it down and it starts right back up on the first turn. I notice an oily mix oozing out of the exhaust ports at the top of the leg. Back to the internet and find that this could be normal. Just unburnt gas/oil because of some pressure equalization thing. It's common when you run on muffs at low rpms. The exhaust cover still leaks, but it's a slow drip. It might just need some tightening up.
So, it looks like I'm off to the boat store to get new trailer tires and a prop to drag this thing to the water* somewhere for a sea trial. *The alternate would have been to go get tires to drag it to go get a used outboard and a $5-7000 kick to the Nortons. I don't think I'll be able to sea trial until two weekends, so we'll see.
