Hello all, just started a 57 seaking by gale. Has great spark rebuilt the carb but it stalls when put in gear unless really up in rpms. I did a compression test and was shocked only 60psi on each! I was expecting at least 75psi. This motor is super low hours. Am I wasting my time? It has all new ignition and wires. Could I have missed something in the carb? Did a total soak, blow out including Welch plug. I redid seals and pump in the lower unit as well as lower crank seals. Thanks Dave

It starts and apparently runs at low speed (?) So, I wouldn’t worry about the compression. So, the big question is why won’t it run in gear?
I really don’t know unless something is binding in the lower unit. Could be the shock absorber broken and winding up on itself under load.

It does start very easily and idles well. When I put it in gear it dies after about 30 seconds unless I up the throttle. Before I put it on the boat and adjusted the high speed it didn’t do this. If I richin the high speed it will run in gear. I was so taken back by the low compression that maybe I just need to go thru the carb again and don’t worry about the compression?

How many turns out are your mixture screws?

Initial settings 1 1/2 low speed and 1 high speed out from lightly seated like all the other Omc motors i have done.

Have you checked the synchronization of the throttle with the cam on the mag plate?

Maybe we aren’t understanding the problem. So, it dies after 30 seconds when you put it in gear, right? Not immediately, right? But it will run at high speed if you set the high speed richer, right? Sounds like a carburetor or fuel supply issue

I’m beginning to think the same thing. I did a clean out on this tank and perhaps I didn’t get it as clean as I had thought.

Sorry didn’t answer your question fully. Yes it idles in gear awhile then dies. This has the tank on top and I’m thinking I am getting stuff working loose
