    Heads on Port side significally Hotter

    I have a 140hp evinrude and the 2 cylinders on the port side are heating up a lot faster than the 2 on the starboard. I have checked all hoses for leaks, replaced thermostat, relief valves, springs, gaskets......no change. Then I replaced the water deflectors under the heads.......no change...

    Cranking resistance since Ran out of Gas

    I have been working on my 1978 evenridue 140hp. I finally had it running like a champ. My last trip I was running almost full speed and ran out of gas. Ever since then cracking has been very sluggish. I removed the spark plugs and manually turned the flywheel and could tell there is resistance...

    Lower Unit clutch dog

    Is it necessary to remove the lower unit to replace the clutch dog? I was hoping that since it's before the forward gear I could access everything through the prop outdrive. I'm suspecting the clutch dog is worn because it's requiring more travel to engage forward or reverse. Right now it...

    Shift rod connector or clutch dog?

    After fixing weak spark issues and a head gasket replacement, I went for a test run today. Rode like a champ. No vibration, quite, smooth, perfect rpms and speed. And then something else....Accelerating out of idle I heard a clunk, felt it slip out of gear a bit. Then while cruisin about 20mph...

I removed EVERY wire from the key switch, through the starter cylinoid, to the power pack. Cleaned every connection and now I have strong spark. HELL YA...

    Weak spark new components

    OK, I've been fighting this issue for awhile now. When I remove the spark plugs I get spark (not always consistent). With spark plugs in I get no spark. I bought a new stator, rectifier, and power pack. Minus the key switch and timerbase/sensor coils that should make up the ignition. Key switch...

    Weak spark - sensor or powerpack

    I have a 1977 140hp Evinrude. I am getting intermittent spark. With all the spark plugs out I get spark on all cylinders. With them in I get intermittent spark. Overall the spark is weak. Battery fully charged, normal cranking speed, and new rectifier. I removed the flywheel and on the inside of...

    Evinrude not firing on cyl 1 & 3

    As of recently my evinrude 140hp is intermittently firing on cylinders 1 and 3. I assume this is probably an issue with my power pack, but would like to verify before purchasing a new one. Is there a good way to test the power pack? Also, correct me if I'm wrong that if the stator or rectifier...

    Head Gasket vs. Low Compression HG

    I noticed low compression in piston #1. Pull the head off and found the Head Gasket was blown out on the bottom. (After finding whomever I bought the boat from switched igintion coil #3 w/ #1 - oops) Anyway I was going to purchase one from iboats but they have two head gaskets listed for a '77...
