    This is a continuation of a Topic I started on 8/4/2019 with most recent posting on 8/19/2019 (moderators please tell me if I should have continued or linked to original thread ). Sorry to leave Joe Reeves and any other folks in suspense about what dimensions this Carburetor has. After an 8...

    During recent move to anot6 state my 1985 6HP Evinrude laid tiller side down in my SUV for about 3 days. The powehead was slightly higher than lower unit.

    Resistance while Rotating Flywheel 1990 4hp Evinrude E4RESR.

    While going the next step in debug of Fouled Plugs condition (see separate Topic I started yesterday on that) I noticed that with both Spark Plugs removed the flywheel is hard to turn at 2 different rotational positions. As a sanity check, on another motor I have (4R75A Johnson 1975 4hp) I...

    Spark plug wires and boot 1975 Johnson 4hp.

    What is best way to reconnect spark plug wire and boot on my 4R75A Johnson? In process of selling this motor a prospective buyer had the 2 spark plug wires out of place as he actuated the cowling lock. Now one boot is off and other wire has a nick in it. Will electrical tape be sufficient to...

    1969 Johnson 6hp Carb leaking fuel.

    My 6R69M ran fine a couple months ago when put into storage. I use only non-ethanol fuel. Yesterday firing it up in water tank carb spewed fuel from front right side when I squeezed the fuel bulb (sorry my photo exceeds Size Limit--I can't post). I disconnected fuel line, mopped up excess fuel...

    On my 1969 Johnson 6HP 6R69M after replacing my Thermostat and doing a thorough cleanout of saltwater residue/crud (due to decomposed Impeller, which I also replaced) there is a leak between my Thermostat Housing Cap 312714 and the Cylinder Head. (Good news is that the Impeller is pushing a...

    Drive shaft pops up during Lower Unit Pressure Test 1985 6hp E6RCOB.

    Due to a broken skeg (which occurred before I bought this outboard) I am thinking of replacing the Gearcase Housing Assembly. There seems to be slight milkish Gear Oil and some water after running with new gear oil in a tank for a just few minutes (to check the Thermostat/PeeStream). It is...

    Best way to flush old fuel line and bulb.

    I recently acquired a very nice freshwater-only metal OMC fuel tank complete with Fuel Line, bulb, 2 fittings and about 1 quart of old fuel. This is a Model 3 (Belgium-made?) vintage I thought around 1998. Although CSA Sticker on the tank shows 2389 (would this be Date Code 23rd week of 1989?)...

    Best Water Pump for 6hp 1969 6R69M Johnson.

    Working on overheat problem (see separate/closed thread on Stuck Head Bolts) I discovered my 5 year old pump impeller was really demolished. To my surprise, my Water Pump Housing is 323596 with Metal Water Pump Liner 324641 and Impeller 763735 and Plate 323597 as would be standard for newer...

    1986 Johnson J10RCDB not achieving high RPM--wrong carburator?

    I recently became the proud (at least third) owner of this outboard. It starts and runs OK at low/medium RPM but won't get to full throttle consistently. Previous owner I bought it from mentioned guy he bought it from may have tried to convert it to a 15hp (and has since lost contact with that...

    Yikes rusty spark plugs!

    Now that I got the jammed cover off my recently-purchased 1998 8hp E8RECR Evinrude I think it would be best to replace these Autolite 425 plugs. Outboard starts and runs fine but plugs are heavily rusted outside surface--worst I have ever owned, or possibly seen on a functioning outboard engine...

    Unseize 1984 6hp E6RCRV Evinrude.

    Bought this for lower unit parts but top end looks so clean I cannot resist trying to get it to run. Was told by seller it seized up during winter storage. He shot PB Blaster into spark plug holes but didn't remove the head. I removed head, it came off easily. Cooling passages need some cleanout...

    1969 Johnson 6R69M Lower Unit Leak.

    While repairing Lower Unit for milky gear oil I discovered the Prop Shaft has in-and-out play of about 2mm. The run-out is near-zero, i.e. no bent Prop Shaft. Is this in-and-out play normal vs. indicative of bad Thrust Washer, etc? The Gear Oil Fill Plugs seem ok although the washers on Plugs...

For example, should the engine be in Forward Gear vs. Neutral vs. Reverse when I separate the Lower...
