    New (to me)motor, swapping a 302

    My goal was reliability and was surprised at Grok's answer.

    New (to me)motor, swapping a 302

    Here is a write-up from Grok on his estimate of the horsepower from the upgrades I made. It is a pretty interesting read. Grok has helped me a lot for any questions I have had and is free. But it doesn't replace the experience of the pros on this website.

    New (to me)motor, swapping a 302

    My 302 is a 1976 190 HP. The difference between the 175 and the 190 is the firing order and the roller cam, which is a GT40 head. I believe they changed the firing order to handle a problem of some cylinder getting hotter and blowing out more often - I don't know that it increases performance...

    Foord 302 lower rebuild

    I will try something like that.

    Foord 302 lower rebuild

    The spline section of the shaft sticks up - I don't have a big vise but can probably clamp something onto it and beat on it or pry it with a big bar, which I do have. I have just been using a vise grip. I will probably concentrate on getting my outdrive back on the boat and deal with the junk...

    Foord 302 lower rebuild

    I got the nut off of the pinion gear, so that part of the shaft is wedged solid. The top part of the shaft turns but won't pull out. The pinion gear is just dangling there held in by the forward gear and the driveshaft. The forward gear and all can't come out as the pinion gear and the bottom...

    Foord 302 lower rebuild

    I got the lower back together and mated it to the upper. I am assuming that the cause for the failure was the spliced shift cables that had separated, as nothing else was found flawed in the lower. I will be mounting it back onto the boat soon. I still haven't been able to get the broken...

    Foord 302 lower rebuild

    Okay, I got the new forward coil and checked it on the meter and it read 7.3! So, I got my other meter and it and all my coils read 5.6 to 6.0, just as I remember - all are good! So, I do not have an explanation of why that lower lost forward, other than maybe that splice in the shift cable...

    Foord 302 lower rebuild

    And there is a big difference in price, $121.60 for the forward and $215.60 for the reverse! I checked out all four of the coils on my two lower units and they are all bad, above the reamended 4.5 -6.5 in the manual. The forward one in the unit that I am going to use is the worst, at 7.2 - all...

    Foord 302 lower rebuild

    I couldn't get the broken driveshaft out. Ot should just pull straight out, so I am figuring something bad happened in there, like the housing is broken or the bearings are somehow blocking the release of the broken driveshaft. One thing I did when installing the needle bearings - the manual...

    Foord 302 lower rebuild

    I did open up the lower - I'm getting pretty good at it. The driveshaft is broken in two!! I haven't been able to get it out yet, but if you twist the top around, the pinion gear doesn't go around. I got the pinion nut off - it may not have been fully tightened, even though I torqued it...

    Foord 302 lower rebuild

    Not the happily ever after report that I had hoped for... I took my boat out to the ocean yesterday and started out slowly building rpm and got to 2500 rpm and I lost forward gear - like it slipped into neutral and engine revved up. I reduced to 600 rpm and checked reverse, and no reverse...

    Water in the cylinders - OMC 460

    I'm not an expert, but if you took off the intake manifold, water in the passages could perhaps leak in through the valves. I know I've found some on top of the block under the intake manifold.

    OMC 260 Inboard, identification and Fuel Pump replacement.

    The new style fuel filter is a good idea, with all 3/8" line and connection fittings. You can see my new filter in the lower right corner with the new bracket I made for it to move it out to the corner there, as it was much bigger than my old one. It also separates any water from fuels with 10%...

    OMC 260 Inboard, identification and Fuel Pump replacement.

    Yes, it is a coolant reservoir, but it is vented and hopefully it would never be used until you replace the pump. I remember seeing dedicated fuel pump reservoirs but couldn't find one quickly on Amazon. I believe they exist.
