    Water in Oil (Again) Head Scratcher

    This is the most thorough investigation that I've seen in a while. If it leaks again, that's your sign to scuttle the boat.

    Mercruser 3.7 488 wiring help

    6 pics, could you label them better? Also can't tell which wires are original color from the plug vs. spliced with a different color. "Feeds most of the engine components"- which components? Pic 2, looks like the main harness from the engine to gauges Pic 3, is there a plug on there? Looks to...

    3.7l to 4.3 engine swap

    Depends on what you have as a donor. Just the block will be an exercise in frustration. A complete donor boat is the best option. Many needed parts they you wouldn't think of

    starting problem with 3.0 mercruiser

    My HF ones are dying slow deaths, as are my tape measures. Makes me sad that I might have to actually buy some at some point.

    2008 Tahoe Q5i 4.3 Mercruiser Engine

    eBay or conversion to Delco. But unlikely cause in your case. TB V (if that's what you have) is tough to find.

    Wideband O2 sensor install

    Took it out today and had my first mate check vacuum readings at different rpms. Af gauge working fairly consistently now except for occasional hiccups. As stated, I think it's sensitive to the 1v or so voltage fluctuations that I sometimes get at the helm. So most vacuum is 20 at idle. It...

    97 tracker party deck

    You'll have to trace out the wires then. For sure you should have separate Nav and anchor lights, and a blower if I/O. Maybe one for radio as well. Do you have a working radio?

    97 tracker party deck

    Sometimes, not usually. Sometimes there's an "always on" and one that only comes on if there's water.

    97 tracker party deck

    No, you won't find anything useful. Flip the switches and see what happens. Nav lights, anchor light, blower (if I/O), radio?, bilge pump, instrument lights, are a few that they might be.

    Odd shift cable fail

    Just bent the spring tabs until I got it even.

    Nola Mike is in Fl

    Just saw this, didn't think @Scott Danforth would publicly admit to meeting me in person. He even sprang for the tacos and beer!

    Wideband O2 sensor install

    Yeah I have the manual. I don't remember what I ended up with as far as combo. The secondaries do open, and then I see it really richen up. I know that my secondary jets are richer than stock, so need to go back down. The problem with a marine application vs auto is that there really isn't a...

    Odd shift cable fail

    Bellows were dry. I thought that there might be some residual junk in there after it got dunked. There had been water in there at that time. The cable was perfectly smooth when I put the drive back on the other day, but it didn't resolve the problem.

    Odd shift cable fail

    Post #3 is the resolve, no the SIS didn't fail. The failure was uneven spring tension on the plate, causing it to move much more easily in one direction than the other.

    Odd shift cable fail

    I understand exactly how it works, which is how I figured it out, thanks. Perhaps you don't understand that adjusting the tension in the spring roller, or its position (if that's what your comment was referring to, but who knows since it was so vague) won't affect the behavior that I described?

    Odd shift cable fail

    It's that secret code? You did?

    Odd shift cable fail

    What's the update? What's the adjustment? Used a needle nose to bend the spring, also was going to use on the roller arm, but that didn't seem to be the problem.

    Wideband O2 sensor install

    I'm wondering if this thing is real sensitive to power fluctuations. I tried direct wiring the positive and negative (individually, cause I'm lazy) with no change. Pt it back, and it works occasionally. Found that the ratio is 14.2-14.9 mid range, and then fattens it over 3500 rpm. Gets into the...

    Odd shift cable fail

    So interestingly enough, it failed again almost immediately on the water. Failure was needing to pull through f->n->r to get out of gear. Going r->n caused it to stall. The cable while not perfect didn't seem overly sticky. Realized that getting out of forward the sis didn't activate until there...
