77 model Evinrude 115 HP outboard motor struggling to turn over

[Dub]

Hey guys, I have a 1977 Johnson Evinrude 115 hp outboard motor that struggles to turn over even with a new starter. I removed all the plugs and it will spend fine but as I replaced the plugs it struggles to turn over. I did a compression test and each cylinder read about 120. Does anybody have any idea what my problem would be. Thanks in advance

Load test the battery.----Inspect battery cables.-----Perhaps check lower unit for binding.

Thanks for the response. I got it to turn over correctly. Now, I just got to figure why I'm not getting any spark.

If it isn't spinning the motor fast enough, you won't get spark. What did you do to get it to turn over quicker?

At first I did not have a controller wired up to crank it with the switch so I was trying to bypass the starting solenoid and and jump started for the battery to the starter. I saw that wasn't getting anywhere so I went ahead and wired up the control box and it's turning over fast now, I'm just not getting a spark. I check to see if I was getting power from the power pack to the coils but there was no spark there either. So I was thinking that my power pack was bad so I replaced it and it still nothing.

I believe there is a 20amp fuse along the harness (motor side) -- might check that just to be sure.

Go to cdielectronics.com for ignition troubleshooting.

Not a pro, but I'd also check to ensure the kill switch lanyard is in place.
Some remotes have the lanyard on the key switch, some have a toggle switch which the lanyard will toggle when pulled.
Sometimes the kill switch is on the dash of the boat.

If the lanyard is pulled, the kill switch will kill the spark, but the starter and everything else will still work.

Just a thought..

My pontoon is an early 80s boat, it doesn't have a kill switch lanyard on the control box.
