    Cylinder Wall Scuffs (Pictures)

    I'm hoping someone may be able to help me diagnose the cause of these scratches / scuffs on my cylinder walls. I have a 50 HP Johnson, 2000 model. On the top cylinder, the scratches are on both the left and right side of the cylinder walls. On the bottom cylinder, the scratches are only on the...

    Johnson Cooling Blockage (picture)?

    Hey all, I have a J50PLSSM. With the head off I noticed what appears to be a blockage of one of the water passages. It's where the warm water flows out of the head on its way out of the motor. The other exit hole is clear. The engine ran fine with this apparently, no overheats and always had a...

    Spark or Fuel?

    I have an issue with a 2000 50 HP Johnson (J50PLSSM). After running for a while at high speeds it will die out on me. It doesn't seem consistent, sometimes it will run fine. Once it dies I can immediately restart it. When it dies it's pretty quick, doesn't jump around at different RPM's, just...

    Johnson 50 HP Cuts Out

    Hey everybody. My 2000 50 Johnson (J50PLSSM) died on me the other day when I was cruising around 4200 RPM. It was a quick shut down, didn't slowly bog down or anything. The engine immediately fired back up and I idled back to the dock. Checked compression and it was good on both cylinders. What...

    Idle timing question

    I have a Johnson 50 HP, J50PLSSM. So I was checking my idle timing and hooked up my timing light to the #1 spark plug wire and cranked her up. It was perfect, 1 degree ATDC matching my service manual specs. Here's the stupid part. Do you also need to check timing on the #2 plug wire?

    That was a close one

    So I was cleaning my carbs this weekend on a Johnson 50 HP 2-stroke. After reassembly, I started bolting down the lower carb and it's an impossibly tight fit. I still have the VRO pump so basically all the space on the port side of the carbs is occupied by the pump and fuel hoses going...

    Low RPM's in neutral / idle, stalling

    Hey guys, Trying to get this Johnson 50 HP outboard idling better. Model # is J50PLSSM, year 2000. So I'm supposed to get 1200 RPM's when it's sitting in neutral but I get way less than that. To get it running I have to warm it up, take it back to neutral and then quickly shift forward and give...

    Idle Too Low - 50 HP Johnson

    Hey everybody, I rebuilt my Johnson 2000 50 HP (J50PLSSM) over the winter and it's been running great... Almost. I have to push the throttle pretty far forward when I shift into forward gear. The idle RPM's in forward gear should be 800 or so but on my tach they barely register 200 - 500. Carbs...

    Finding the Right Prop

    Hello, I have a 1986 14' Bayliner Capri that has a 2000 2-stroke 50 HP Johnson outboard on it. The boat weighs 700 lbs. The motor came off a pontoon, so the prop is probably not the right match for my boat. The current prop is an aluminum 3-blade 13" pitch / 12.5" diameter, part no. 775713. When...

    Can a rebuild affect timing?

    Does the actual rebuild process of adding oversized pistons affect engine timing? Or is it purely controlled by the link and sync settings?

    Timing Questions 50 HP Johnson

    Hello, I have a 2-stroke 50 HP 2000 Johnson (J50PLSSM) I'm trying to get ready to go. Powerhead has been rebuilt and Link/Sync completed. I hooked up a timing light and using Joe Reeves static timing method, my engine seems to be a few degrees under what it should be based on his documentation...

    Problem Testing For Spark

    Experts, please tell me where I'm messing this up. Trying to test for spark on a 50 HP 2-stroke Johnson: 1) Remote starter switch hooked up to crank the motor instead of using keyswitch 2) Spark plug gap tester (from Autozone set to 7/16") hooked up to plug #1 and grounded to headbolt 3)...

    Timing Questions - Johnson 50 2-Stroke

    Hey all, I'm wrapping up a rebuild of my 2000 50 HP 2-Stroke johnson. I've completed the link-and-sync per the manual but wanted to give Joe Reeves timing method a go since I don't have proper test wheels and tanks, etc. I have a few questions about the procedure. 1) What's the preferred way...

    System Check Gauge Tach Compatibility

    Hey all, I'm looking to add some instrumentation to my boat to hopefully give me some warning if it plans on blowing up again. I have a 2000 50 HP 2-stroke Johnson. I verified under my dash that I have an 8-pin female connector, wiring looks like this...

    Torquing Rod Bolts

    I'm working on torquing some rod bolts for a rebuild of a Johnson 50 HP. My factory manual tells me the torque should be 30-32 foot pounds. I have a 1/2 inch drive that has a range of 20-150 foot pounds. Anybody know what 30 foot pounds feels like? I was pulling pretty hard and still haven't...
