Hi guys. I'm really beating my head against a wall with this 1966 Evinrude 5602R 5hp. I bought it about 8 years ago, and it ran great until the back of my boat got swamped at shore. The motor wasn't anywhere near submerged, but water was splashing up near the cowling. From that point forward, this motor has been useless, just would either never start, or wouldn't stay started.
I actually got the beast running recently, but it would die after less than a minute. Also, the carb would would pour gas out from seemingly everywhere when I would pump the bulb up. So, I rebuilt the carb with a new kit. I soaked the large parts in carb cleaner, blew out the passages with compressed air, and reassembled. I was convinced that this was my ticket to making this thing run again. Wrong. I can still get the carb to overflow fuel, but it's harder to make that happen now. The motor is still hard to start, and will still die eventually. I can see my Craigslist ad now, "Starts in the first 50-75 pulls!" (No, I'm not selling this, I want to go fishin') If I gently squeeze the fuel bulb it sometimes will keep the motor running, but sometimes it acts like it's killing it and will make it stall. It will be running like a champ, then just start bogging down and die. Right now I'm thinking it's fuel delivery related.
Here's where I'm at from a technical standpoint:
Takes 50-75 pulls to start. Once it stalls, takes another 30 to get it going again.
Checked the resistance and continuity on the coils: pass
Have not checked the point gap, however the motor, when running, runs amazingly.
Both cylinders have consistent spark, even when it starts to sputter and die. Checked this with an inline spark checker.
Checked delivery line for cracks, however I'm suspicious of air leaks in this old line/primer bulb setup. I cut off a small section to redo the connection, and while the outside looks a bit old, the inside of the tubing looks amazing still.
I am super suspicious of the fuel pump, but I can't find a rebuild kit for the 1966-1967 models, and the rebuild procedure I found online is super-duper complicated and in-depth. Since I just came to this conclusion yesterday, I haven't had time to look into this solution.
I've also read that old condensers can heat up, and cause an ignition fault, but I'm still getting good spark all the way through it's stalling process, so I really don't think it's ignition related, but I'm open to suggestions.
Thanks in advance!
