    Surface Gap Plugs in '98 25hp

    I'm getting ready to do my winter layup on my '98 Johnson 25hp twin. In the past, I've bought new plugs every year, gapped them, and installed after the motor was fogged so everything was ready to go in the spring. I notice that L78V surface gap plugs are listed as compatible in this engine...

    1961 5.5 Fisherman - Lower Unit Reseal

    Ok - i've got a 1961 5.5 fisherman that runs like a swiss watch but the lower unit lube had SIGNIFICANT evidence of water intrusion. Drained the gear lube and replaced the compression washers at the fill/vent plugs because they looked a few decades old. I'm going to run the motor this weekend...

    Replacing Bench Seats

    I've got a 14' Sea Nymph Cartopper who's seats have seen better days. It seems as if there are brackets riveted to the hull and then the seats are riveted to the brackets. There are cracks in the aluminum on at least two of the seats. I'd like to replace all of the benches with a carpeted...

    What would you pay?

    I'm considering buying an overhauled l/u for my 86 Merc 90 Inline 6. My current gearcase has been resealed at considerable cost and still leaks. I was even told that it held 15 psi overnight - but three hours in the water and I had a milkshake. I'm seeing some on Ebay but they're all over...

    68 Johnson 9.5 Impeller / Thermostat?

    I have a 68 Johnson 9.5 that I recently sent off for an impeller because i couldn't get the l/u separated. Apparently it took about six hours of heat and wd40 for the mechanic to get it off. The first impeller separated from the brass before the motor was returned to me. I supplied a second...

    Here's a good one - MQ14E - Broken Lower unit attaching stud

    Went to drop my l/u tonight so i could do the water pump while i wait for other ignition parts. First two bolts came right out. The third snapped within a 1/4 turn. If you're familiar with the 9.5 L/U, you'll know that the anti-ventilation plate really gets in the way if you were thinking of...

    High Tension Leads (spark plug) 1968 9.5

    I'm redoing the entire ignition on a new-to-me 68 'Johnson 9.5 The original wires are shot. The assembly is OMC 0580186. I'm not having any luck sourcing them. I tried to make my own leads with modern spark plug wire but can't get a spark through them (carbon graphite cores?). I've been to...

    Johnson 9.5 powerhead "slop"

    I'm reviving a 1968 9.5 for my 14' tinny. I've been told that a certain amount of powerhead movement is expected in these motors, but how much? Is there a certain way i should move and measure to see if it's OK? My manual is in the mail.

    Fuel Tank Repair

    Sorry if this is in the wrong place - feel free to move it wherever. It's not an engine repair so i didn't want to put it there by default. I have a three gallon OMC fuel tank in very good shape, except for the pickup tube has been pulled off of the tank. See the picture to see what i mean...

    Need a part #

    I'm replacing the water pump impeller in a 1960 Evinrude Fisherman 5.5 . I need a part # for the powerhead base gasket. I went looking on iboats but they're not broken out by model, only by part#. BRP's website only goes back to 1968. Can anyone help?

    I think i found a good one

    I picked up a 14' Sea-Nymph today and on the back of it was a 1960 Evinrude 5.5 Fisherman. Started right up on the second pull. Looks like the plug wires have been replaced, so i'm assuming the igniton components have been at least looked at and probably replaced. I'm getting a mist out of...

    So, this is why i should have bought a spare

    Took my boat out yesterday evening to our local river. The river's been down for about three weeks because we haven't had any rain. I've made this run a dozen times before without problems, but apparently all the stars aligned and took out their aggression out on my prop. Struck a submerged...

    This should be easy - carb removal on 1986 Inline 6 - 90hp

    Ok - i've got my carb kits and my plan is to rebuild all three carbs one at a time, starting with the bottom carb because the idle circuit appears to be plugged. Motor will not idle but if i start it above half throttle it runs like a champ. I can not for the life of me figure out how to get...

    Welch Plugs - Back Drag Carb Rebuild - 86 90 I6

    Got my 90hp I6 back up and running. Ran great for about an hour on the river. and then would not idle. Pulled cowlings and found the bottom carb dumping fuel out of the vent jets. Read the plugs and 5+6 were lean, as expected. I'm going to rebuild all three carbs and try again. My manual...

    locate serial number

    Gents, this is a silly one. I have a Mercury 90 Inline 6 which i believe is a model year 1986. I've only found one serial number sticker on the transom bracket, which is completely faded. Is the serial # located anywhere else on this motor? So far i've just been making wild guesses when...

    1986 Merc 90 i6 - stator replacement labor

    Gents, Recently lost spark on 1-3-5. Diagnosed as bad switch box. Replaced switchbox and questionable rectifier. Still no spark on 1-3-5. Engine will start and once i give it gas, 1-3-5 kick in. So, i'm thinking that my stator is bad. I'm handy, but i don't have the tools or a source for...

    1986 Merc 90 Inline 6 - No spark on 1-3-5

    Evening gents. I have a 1986 Mercury Inline 6, 90hp. It was running well until tonight. While pulling away from the ramp it quit and was very hard to get restarted. Got it "sort of" running long enough to get out of the current and back to the dock. Hauled it out and when I got home found...
