i was able to find the welch plug that i was told about and i got this number. j3007930 i tried to look it up but had no luck. could someone help me out with it please?
I am not familiar with that code. I know if it is later than 1980 it will have an apha numeric code like my Johnson is a J120TLCL and my parts numbers are usually 6 digits. The big dogs on iboats will give you a better hand. Again welcome.
it looks like the plate was knocked off. the boat is a 76 seastar 16' tri hull. so i figure the motor is around that year too. but i saw there was several manuals for the 55hp around that year.
It looks like all 55 johnson 55 hp models were built between 1968-1979 Year Model 1968 TR-TRL-10 1969 55ES69-55ESL69 1976 55E76-55EL76 1977 55E77-55EL77 1978 55E78-55EL78 1979 55E79
55R79-55RL79
Near as I remember (asking a lot) they were pretty much the same. Go to the Evinrude site and compare parts. Anything in particular you're concerned about or just in general?
well i just bought it off craigs list. the guy told me the carbs needed rebuilding. i have never worked on a marine engine but alot of automotive. everyone tells me i should get the service manual for it and also the parts list. so i guess its just in general.
Agreed. The OE service manual will pay for itself in the carb job. Very simple, don't be intimidated by what you see. It looks way more complicated than it is.
Post as you go thru the carbs. There's a trick or two you can do that's not in the manual.
The starters were different from 68 to 69 and the flywheel as well, 12 tooth versus 9 tooth....the thread below will detail this.
So, if your starter gear has 12 teeth, you almost certainly have a '68 TR-10.
If you have a 9 tooth, it is probably a '69...although there would be a slim possibility that someone MAY have put a 9 tooth flywheel and starter on a '68.
There are also a few differences in parts between the 2 years, but the on-line parts descriptors are there for both '68 and '69 so you can double check the part numbers if you are in doubt.
