    Checking the Wiring of the Assist Solenoid

    1991 Ford 5.8 Ltr I disconnected a few wires from the assist solenoid in order to gain more access to the valve cover on the starboard side. I thought I had taken enough pictures, but apparently not #@&. I have the OMC shop manual and the wiring diagram; see attached. The reason I'm...

    What is the Best Way to Repair the Snaps on a Sunbrella Cover

    The boat comes with a very well made cover that snaps onto the boat in many places. A lot of the snaps have torn out of the cover. I'd like to add small doublers and then use my snap kit to add new snaps. I tried using iron on patches but they do not stick to the Sunbrella fablic. Any...

    How do I Remove Very stuck on Exhaust Manifold Gaskets?

    I'm changing the exhaust manifolds. They came off easily, but the gaskets are really stuck on the engine block. They may be the original and 35 years old ! I've tried a hard plastic scraper and gasket removal spray. I have a one-sided razor, but I'm concerned about cutting into the metal. So...

    Have you cleaned and resurfaced exhaust manifolds?

    This is on a Ford 5.8 Ltr with an OMC OD. Have you cleaned and resurfaced exhaust manifolds? I have a few other posts about this. The motor was running hot but only on the port side exhaust and riser. The engine temp was right in the middle. On removal, there was rust and a partial blockage in...

    5.8 Ltr Ford, OMC OD. 1991 I'm changing the risers/elbows. I already have those. I am considering replacing the exhaust manifolds as well. The motor has been running fine. It starts easily, has plenty of power, and doesn't burn oil. Just to be sure, if there were cracks in an Exhaust Manifold...

    Hard Lime Green sealer/Filler (?) on Exhaust Manifold

    91 5,8 Ltr OMC/Penta V8. I'm changing the Elbows/Risers. I was overheating only on the port side. See other post I'm cleaning the mounting surface on the top of the exhaust manifold where the gasket will be, and on the port side there is a very hard sealant or something. BTW, that is the side...

    How Do I remove the Thermostat from the Housing, Ford 5.8

    How do I remove the thermostat from the housing on a 91 Ford 5.8? The shop manual only says, "The Thermostat is held in place with an O-Ring. Pry the O-ring out of its groove, then lift the thermostat out of its housing." The inside of the housing is a bit rusted, and it is hard to see the...

    1991 Four Winns 200 with 5.8 L Ford V8 and OMC OD. I was cruising the harbor on Sunday with friends and noticed overheating at the port exhaust elbow. The engine temp gauge was only slightly above the midpoint, so it was approximately 172 Deg F. The starboard elbow did not seem as hot. I was...

    What do you Recommend for Beautifying a Teak Swimstep?

    My 1992 Four Winns Horizon 200 has a nice Teak swimstep. It does require regular maintenance to have it looking its best. I have used Teak Oil and occasionally Teak cleaner and then Teak oil. I did not use the Teak oil this time, so I do not have a picture. I did not use any varnish this...

    Sealing the U-Joint Bellows watertight on an OMC Cobra

    On an OMC Cobra getting a watertight seal on the U-Joint bellows is critical. If water gets in the bellows it gets onto the U-joint and the gimbal bearing. Those items can quickly rust, resulting in expensive and complex repairs. (Believe me, I know!) The forward end of the bellows is sealed...

    Is this Water Pump to Gear Housing Adapter Installed Correctly?

    This is part of the "Upper Gear Housing Unit" per the Crawley Marine diagram. See picture: I do not have a press, so I installed the Water Pump Adapter Seal, # 47 into the Water Pump to Gear Housing Adapter, #45 by tapping it into place with a socket and a hammer. I think it was fully...

    Help - I sheared off the bolt holding the Shift Lever on the Bell Crank!!

    Help! I screwed up! I was putting the Bell Crank back on the boat and was tightening the bolt that holds the shift lever on the bell crank. The original OMC Shop Manual said 5-7 ft -Lbs. I was using a torque wrench. I got to 5 Ft-lbs and was going just a little more… The bold was sheared off...

    What are some ways to prevent corrosion and a stuck gimbal bearing? I had to fight a stuck bearing that took a lot of effort to remove. See the post titled "How Do I Remove a Stuck Gimbal Bearing" I know, there should not be any water on the bearing and then there would be a lot less...

    How Do I Remove a Stuck Gimbal Bearing?

    I could use some suggestions for removing a stuck gimbal bearing. Water got into the U-Joint bellows and onto the bearing and it rusted. I did not think that the rust was that extensive because the boat was running fine but had a slight rumble in the bearing. The water getting into the bellows...
