I recently bought an 1980 Carolina Skiff J12 and in the deal got a non running/or has not ran in several years 1962 Evinrude 18hp Fastwin motor. This is a winter project and I am starting to get into the motor. A few questions to get started.
Last night I drained the lower unit and had a just a slight bit of water, very little.
What is the best lubricant to fill the lower unit back up with?
There was no fuel line with the motor.
Is there a universal part number for the connector? I did get a new fuel tank with the deal, but need hose and a bulb.
Also what should be my next plan of attack after I get the fuel hooked up and the lower unit filled?

thanks for any help, I have been doing searching for the last week and understand I should get a new impeller.
Does any have Napa reference numbers for these parts?

Admin,
Can you move this message to Evinrude Outboard motors? Not sure why I posted in this section.

If there is water in the lower unit you need to install a seal kit.

If you have a NAPA near you, and no dealer you can use the following part numbers. Or you can even order here on iboats.

The fuel connectors from Sierra come in 3/8 or 5/16 sizes. Part number for 3/8 is 18-8092. 5/16 is 18-8056

The bulbs come in same sizes. 3/8 is 18-8005EP-1, the 5/16 bulb is part number 18-8004EP-1

Of course, then you can buy the fuel line to match the bulb you get and the connectors you get. Or, make it easy and buy the OMC fuel line and connectors and line all wrapped up together ready to use. Part number 18-8009EP-1. The OE number for this is 398549 from the dealer.

The impeller for your motor is 18-3002

Step 1 before anything though is test compression. Should be between 100 and 150 psi, and even between cylinders.

Then test spark. Get an adjustable tester, set it to 1/4". Spark should jump that with a bright blue ZAP!! If not, pop off the flywheel and see why. Could be original coils, if so chuck em and replace. Polish points and set to 020. We can talk about that later though when the time comes.

These are pound for pound great motors, and if taken care of, will outlast your grandchildren.

High Trim, dumb question on the fuel connector's. Should I just measure or are they interchangeable? Also I am doing a compression test this weekend and will test the spark. It was sparking but it has some old Autolight plugs in it.

thanks for your help.

Either size will fit your motor. The 3/8 is mainly for higher hp motors though, as it provides a bit more flow. The part that connects to the motor though is identical, they only differ in the barb that accepts the fuel line, that part is a different size.

Compression was checked today and is only 60 PSI in each cylinder. I also checked thespark plugs with a tester and spark was very weak.

Not sure if I feel like the engine is worth keeping and spending money on. I may just part it out or sell cheap on Craigslist. Or the trash.

Thoughts?

Well, that is why testing compression is always step 1 before spending money.

That being said, do you trust your gauge? Do you trust the results? Strange that both cylinders are exactly 60 psi, unless the only problem is a small tear in the head gasket BETWEEN cylinders, which would explain it. Don't fret yet. Pull off the head, and inspect the gasket.

I have another tester but it is a rubber "push in" and can not hold it with one hand and pull the cord.
There is some grinding noise around the fly wheel when I pull the starter rope.
I will try and test with the other tester tonight.

You will need a " long shaft " motor.---As it is now it is a short shaft.---Lucky you , this motor was made for about 20 years and extension kits are easily found.

60psi on both cylinders? Part out the motor.

If not, and you want to start digging into it, there are parts diagrams for your motor in multiple websites online. Just google "Johnson Evinrude Outboard Parts Diagram" and you'll find some. Parts diagrams are readily available from 1955 until present for OMC/Johnson/Evinrude.

I would not part it out just yet. I would almost be the problem is a torn head gasket between cylinders. Very common, and an easy fix.

Sold the motor this weekend.

I felt like after time and money I would be able to pick up something running.

to bad.... good engines .... easy to fix up with minimal costs ..usually just coils impeller carb kits

short shaft was your main concern not 60 pounds per cyl

. imho... soaking& decarbing an old engine could have helped ... it was well Worth a try
