    1990 Johnson 125HP Cylinder Head Replacements

    I'm having trouble finding replacement cylinder heads for my 1990 Johnson 125HP V4. The part number is 432592, and it shows replaced by 0436004, then by 432592, then by 0438527 which shows unavailable/obsolete. Once and a while on ebay, the part will show up, but it looks almost identical to...

    Fuel water separator required?

    I have a 1990 Johnson 125HP outboard that is currently running off a 12 gal Atwood portable tank on the deck (under a seat actually). I'm using the portable tank until I can tackle the leaking below deck tank. My question is whether I ought to run a fuel water separator? Right now I'm plumbed...

    Trying to bring a '90 Johnson 120HP back to life that's been sitting for 5+ years. Problem appears to be spark, but in trouble shooting to that point, I did check the compression on two of the cylinders. Both read 90-100psi. Seemed low for a 2-stroke, but the shop manual said the actual value...

    Low Voltage at Helm - nothing happens when I turn the key

    Forgive me if this is a simple question or has already been asked - I couldn't find anything exactly like this. I recently came into possession of a '92 Four Winns with a '90 125 HP Johnson outboard. The boat has been on a lift and hasn't touched water in more than 5 years. I don't have...
