    Mercruiser 165/470 cooked a coil

    I got thinking about it more, and I think the resistance wire went out last year which lead to the points burning up and everything else going south. By replacing everything but the wire, it left the problem in place by only treating the symptoms which lead to the coil burning up this year.

    Mercruiser 165/470 cooked a coil

    I have a 1987 FourWinns with the dreaded 4cyl 165/470. Last summer the points burnt up and I replaced the points, condenser, rotor, cap, coil, wires, and plugs. It was due for a tuneup anyway. After all that, it ran like a top. We didn’t run it a whole lot after that, but it ran fine through the...

    Impeller housing and oil leak questions

    I’ve pressure tested it a few times now, with odd results. I put it back together this morning and had a leak. Before taking it apart, I worked around and tried to find the leak with soapy water with no luck. During this, I had to pump it back up a few times. At one point, I pressurized it to...

    Impeller housing and oil leak questions

    The new pump base looked the same as the old, outside of just being a different color.

    Impeller housing and oil leak questions

    I wrapped a cone attachment (like you’d use for a beach ball) in electrical tape and jammed it in the oil passage line to the top, and pumped it up to almost 20 psi and it held pressure. Granted, the top half was up side down, so maybe that makes some degree of difference. How would you find...

    Impeller housing and oil leak questions

    I just did, and I’m even more stumped now. I tested it before I took it apart, and it leaked (obviously). I tested each half separately, and they don’t leak. It makes no sense. The oil on the top of the impeller housing says the oil is coming from the top half and running down the drive shaft...

    Impeller housing and oil leak questions

    I just pulled the impeller off and the base appears sealed. If nothing else, I’m not seeing the light like I was when I installed it. Now to figure out where the oil came from.

    Impeller housing and oil leak questions

    I just replaced the impeller on my Alpha One Gen 1 and ran into a couple issues. When installing the pump base, I had a heck of a time getting it to seat fully, and level. I ended up going back to the stock base as it looked like the new one had developed a small crack. I’m fine running the old...

    Fuel Filter Location

    I have the long sought after 165 4cylinder, and want to add a fuel filter/water separator as we seem to run into fuel issues almost every year. The $40 seems well worth the investment for my sanity. That said, I'm trying to figure out where I can put it within the engine compartment. I'd be...

    Merc 165 Surging

    I've got an '87 Merc 165 (the in-line 4) that's giving me a bit of a problem. It's been rebuilt a couple times, the most recent being crank and lower rod bearing replacement (turned the crank as well). When we put it back together, we ran it for a couple hours last Fall, just before storing it...

    165 Rebuild died, need info

    My father-in-law rebuilt the motor in our boat earlier this summer (1987 Four Winns 190 Horizon with the Mercruiser 165 (I4)) after 1 of the 4 pistons gave up the goat in the oil pan (piston skirt broke right off, the other 3 were getting ready to do the same). It was determined at the time...
