    89 5.0 fuel pump

    Trying to get boat started and am not getting fuel to carb. I even tried attaching a short piece of fuel line and stuck it in a gas can. Held my thumb over the end of it while cranking, couldn't feel any suction. Can the fuel pump be rebuilt or is it better to just buy a new one? Original part...

    As long as motor is running >3000 rpm the alarm never sounds. If you run it for 10-15 minutes below that, the alarm sounds (constant tone); increase throttle back to >3000 rpm the alarm will stop. Previous owner had oil reservoir and water pump replaced trying to fix the problem to no avail...

    tilt-trim issues

    I followed a troubleshooting guide posted previously by Don S. and it indicates that my relay is bad. My boat is an 89 OMC (502BPRMED) with a one piece relay box that mounts to the hydraulic fluid reservoir and it is a VERY expensive part (https://www.crowleymarine.com/parts/2982.cfm). I saw...

    89 OMC 5.0L Ford - no spark

    Boat has been running great with no problems whatsoever. Got it in the water, idled away from dock past no-wake sign and gave it full throttle and it died.

    Impeller replacement

    So as I mentioned in another thread I have rectified my shifting issue...YAY!! when I had it out yesterday my temperature gauge was registering quite a bit higher than it was before.

    shifting issue...

    So I am having issues with my boat going into forward gear. I have an official OMC shop manual and I went through the entire checking and adjusting procedure and I thought it was fixed because it was working great in my backyard. I took it to the lake and sure enough, it won't go into gear. I...

    position of boat on trailer and tongue weight

    So I looked at the video in the sticky and I understand how important tongue weight is now. As you can see from the pictures the bow of my boat is up against the front bumper (?), the hull is making good contact with the bunks, and the rear of the hull is hanging off the back about 6 inches. I...

    Prop change question...

    I have a 20' runabout with a 5.0L V8 engine. Manufacturer's shop manual says WOT should be 4000-4400 RPM. I am currently running a 14-1/2 x 19 prop, WOT is 4200, and top speed is 40 MPH. So everything looks good on those numbers as far as I can tell. Had it out on the water with the wife and...

    Replacing freeze plugs

    I have an 89 model OMC 5.0L that is missing two freeze plugs. I replaced one with the expandable rubber seal type, but the other one is behind the motor mount and the gap is too small to get the freeze plug into. I figure I am going to have to pull the motor to get to it unless someone on here...

    OMC 4.3L HO with cracked block

    Well, I bought a project boat and got to looking around and noticed a crack in the engine block. You can see the crack in this picture. It's right at the top of the block on the front port side of the motor. Is it possible to tell from the location if this was from freezing or a thrown rod or...

    New boat project

    I have just acquired my first boat, a 1991 22' Galaxie deck boat that has been sitting in a yard for several years collecting leaves and dirt. It is a major project for sure and I have just started cleaning it up. Time will tell if this was a wise decision or not. I only gave $600 for it and I...
