    How Can I Prevent Fouled Spark Plugs When Running at Idle for a long time?

    How can I prevent fouled spark plugs when running at idle for a long time? Better yet what can I do to clean the plugs without removing them? I've been having a great time cruising in my local harbor, looking at the Christmas lights on the houses along the harbor. The problem is, when...

    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...

    Can I Prevent Corrosion and a Stuck Gimbal Bearing?

    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...

    Can I Tell if Water is Getting into the U-Joint Bellows?

    Can I Tell if Water is Getting into the U-Joint Bellows without taking the OD off? I have to replace the gimbal bearing due to water getting into the U-Joint Bellows. I may also have to replace the U-Joints as well. That was caused by a clip from a grounding strap getting loose and wearing a...

    I know water got into the U-Joint Bellows. I have taken the OD off and can see the rust on: The gimbal bearing and on the U-Joints. The question is: Did water get past the seal in the bearing carrier and into the gear oil? I drained the oil and it is blueish-green. See the pictures below. What...

    Is there a way to check for a leak between Transom and OD?

    I just pulled my OD, an OMC Cobra. I have a leak and a vibration. Water was getting into the U-Joint bellows. That caused rust on the U-Joint and damage to the U-Joint bearing. (there is another post about that called XXX.) I thought that I was careful to prep the surfaces well last time. I...

    Installed new Trailer Bunk Guide-Ons and Carpet

    I installed new bunk guide-ons and carpet on the trailer for my 20 ft Four Winns. The carpet on the guide-ons was very worn and coming apart. I did this with the boat on the trailer. That meant I had all my tools, a work bench, power, and I could do it over a few days etc. That worked out much...

    How Do You Remove The Horn Cover - 92 Horizon 200

    How do you remove the horn cover on a 92 Horizon 200? I can see the screws are removed from the outside but they are covered up by a plastic piece that must come off. It looks like the cover snaps in place but I don't want to pry too hard and break it.

    What was Causing this Clunking Sound? Binding Brakes?

    Boaters, I took my 20 ft Four Winns to the gas station (along with a a few diamonds to barter) and noticed a clunking sound. I had a friend drive it slowly as I walked along side. The sound was coming from the left side and did not seem to match the tire rotation but that was hard to tell. I...
