Pull Start Spring Issue - 8HP Chrysler OB

[coronado25]

Sorry for the newbie termonology...I'm not an outboard expert at all.

This weekend a spring fell off the pull start cog, and I'm trying to figure out how it is reattached, or if it broke. The motor is model 83HC, Serial 1145. The spring is basically a snowman (two circles attached) with a leg coming off at a 90 degree angle. It was used to push the cog in the correct direction so that the cog will throw up in to the flywheel, and then stay down during pull start, and operation respectively. Currently it just rotates with the pullstart shaft, and doesn't throw up into the flywheel as it should.

I'm looking for a schematic of this setup so that I can try and fix this myself. It should be pretty simple, and i'd rather not pay for a repair.

Thanks in advance.

A lot like that. Part 3 is what I'm talking about. It is shaped a bit differently, but same idea. I actually just bought a manual in pdf format, it's great.

If that spring popped out, can i just put it back in, or do I have bigger issues. If I push the cog up into the flywheel, I can start it no problem. It just doesn't do it by itself.

Also, what is a typical price to get the engine completely serviced. I realize there are different levels. I just bought this boat, it's been sitting for probably 3 years. What should I be looking to do to get it back in shape?

Bad news is part 3 is no longer available. Service for these motors is getting hard. Not many people around working on them anymore. Best would be for you to learn how and do it yourself. Maybe try chrysler crew on thursday nights for their discussion and see if you can find the part you need from them. If motor is working good just change the impeller and make sure you drain and fill the lower unit each fall. Would not hurt in fall to fog the motor with fogging oil before you put it to sleep before the winter.

I actually have part 3...just need to know how to put it back in...but with the manual I got, I think I'm all set, going to tackle it tomorrow.

This motor hasn't been run in 3 years...i ran it for 6 hours straight at full throttle with out a problem right off the bat. Then 3 days later, I tried to go about 6 miles, and halfway into it, it cut out. I think it was a fuel delivery issue. this is when I had the spring issue. So i need to fix that, then tackle the fuel issue.

Is there anything specific I should do to it right now considering it has been sitting for 3 years? clean the carb? grease, etc?

Not sure what kind of fuel pump it has but I would rebuild that and then the carb as well if you can find a kit. Replace primer bulb and all fuel line as well. Total cost is around 50 bucks. To start though I would at least get the pump rebuilt. Looks like the part number 27-818043A1 is for the diaphram and gaskets for the fuel pump and cost about 7 bucks and maybe a fuel pump filter 22-F901811 for 5 bucks. All from mercury. See how that goes then go to the next step if things are running good. Walmart sells primer bulbs and mercury should have carb kits for that motor.
