    Head gasket orientation 1990 4hp E4RESR

    Racer thanks for clarifying Metering Rod vs. that hose. Have you used Lumiweld personally on a similar repair? If so, did the repair last for a reasonably long time? I aim to sell this motor ("thinning the Herd") and I wouldn't want to saddle any Buyer with a lemon...been on the receiving end of...

    Head gasket orientation 1990 4hp E4RESR

    Crosbyman, you're right! There is a very slight asymmetry at the top. Thanks a lot. BTW reason for Cylinder Head replacement is shown in photo below. Head blew/eroded a hole at Lower Cylinder on Right/Starboard side (see pencil point). The Cylinder wall itself is OK so I did not need to...

    Head gasket orientation 1990 4hp E4RESR

    Replacing the Cylinder Head and Head Gasket. What is correct orientation of the head gasket? Diagrams show correct gasket orientation would be that 2 large holes for water circulation go at top during assembly. I "get that" . But why is there a small hole at bottom of gasket (see lower arrow...

    Newly bought Johnson 7.5

    Gage R, those old 7.5hp are good motors. Go to "Leeroy's Ramblings" if you want to learn how to disassemble debug and maintain those old gems.

    Outboard Painting

    I am going to hold off any spray painting until warmer weather, then do it outside when wind is calm. I have only 2 or 3 small jobs to paint. However if i ever broaden into more extensive painting, it is good to know what precautions I should take. Thanks.

    Outboard Painting

    Thanks for this discussion/reminder about toxicity. Before i retired i managed a project to eliminate toxic substances in electronics PC'S (RoHS vs. Non-RoHS). I remember hexavalent chromium was one of the materials we had to phase out. It was The Project From Hell. But we got it done. I will...

    Outboard Painting

    Thanks Jim. I value your opinion and the opinion of anybody else who has actually used the substitute product. I will hold out and buy the Zinc Chromate product next time i am already driving the hour or so in direction of a marine store that sells Zinc Chromate spray.

    Outboard Painting

    Is the Rustoleum Self-etching Aluminum paint (in a rattle can) a good substitute for Zinc Chromate (various brands in rattle cans). I don't live near any store that sells Zinc Chromate and Shipping Cost from online suppliers costs as much or more than the paint itself. I will be using a heat...

    Need Kill switch Repair vs. Replacement 1985 6hp E6RCOB.

    Without cutting the 2 wires I was able to create enough slack thereby able to pull out the Kill Switch Assembly. An interesting design to say the least! I did this on 2 Parts Motors and the the "recipient motor". By the 3rd time i had disaasembly quite mastered. I soaked the 2 Rubber Bulbs from...

    Need Kill switch Repair vs. Replacement 1985 6hp E6RCOB.

    BTW Sierra p/n MP28870 is a Stop Button with Lanyard for $25.99 that could mount on the Lower Cover or possibly even be fitted to the Tiller. Good alternative to OMC 398692 or equivalent 583974 which costs $143, correct?

    Need Kill switch Repair vs. Replacement 1985 6hp E6RCOB.

    OK on the donor/PartsMotor I succeeded in creating enough slack in the 2 wires to pull the TwistGrip/StopButton off the Tiller Arm. Whether i use the donor motor Switch or a later model Stop Button with a Safety Lanyard then on the I will need to remove the Switch from the Twist Grip. How does...

    Upper Water Tube Grommet Replacement 6hp 1985.

    I cannibalized from a Parts Motor part #10 Cam Follower and Lever (in the Recoil Starter diagram). In the motor i am fixing i found that the hexagonal mating surfaces between the black and white components were stripped/rounded-off in this Part #10. The interlock works now! The only problem...

    Need Kill switch Repair vs. Replacement 1985 6hp E6RCOB.

    Vic, thanks but i already pushed in the Buttons (yes there are 2 of them) and the twist grip came off partially--but then stuck (see rightmost photo above). It feels like the electrical wires to the switch are stretched tight, not allowing the grip to be pulled off any further. Does this sound...

    Photos added, sorry my camera in phone doesn't link to my laptop. Throttle Cable far end befor i removed the linkage to Arm, and Throttle Grip partially removed (but not far enough to access/remove Stop Switch Assembly). I am stuck here...

    Need Kill switch Repair vs. Replacement 1985 6hp E6RCOB.

    On one of the "Parts Motors" that I have , the silicone soak method may have softened-up the Rubber Button enough to give this "one last shot" before I resort to installing a Dig-key etc Momentary Push Button Switch on the Lower Cowling. I hope this will also allow me to use (from the Parts...

    Need Kill switch Repair vs. Replacement 1985 6hp E6RCOB.

    Thanks Racer for the input. I too can't understand the overengineering/pricing. I am tempted to do the lower cowling switch as you suggest. I saw on youtube or similar a person installed a nice-looking pushbutton momentary switch for $5-10 from a farm supply store...

    Need Kill switch Repair vs. Replacement 1985 6hp E6RCOB.

    Does anybody know a cheap/redneck fix for this Stop Switch Assembly? It could be p/n 396115 or 398744 or 583975 for this Model/year. The rubber bulb is broken and I am unsure what other components were lost/misplaced when the bulb broke (while Previous Owner had the motor). Retail Price...
