Late 60s/Early 70s Evinrude 18 HP Outboard Motor
Posted on 8/26/19 at 9:31 am
Posted on 8/26/19 at 9:31 am
I have an old Evinrude outboard, probably a '69 - '71 model, 18 HP. It hasn't run in years...many years. It has been sitting in my dad's garage, untouched.
I would like to get it rebuilt, question is, is it worth it? What do you think is a ballpark price on rebuilding an old motor like that?
It ran when put into storage, but that was probably 20 - 25 years ago.

If it were me, I'd junk it and get a new or "newer" one. Plenty of really good used ones available.

I have a 68 johnson 9.5 that had been sitting up for a few decades. I changed the fuel lines, rebuilt the fuel pump/carb, impeller, and replaced the coils. It started right up. There is plenty of info about fixing them on youtube. I had fun with it.

Memories, dad rented a boat on Gurrerro when i was 10 that had that motor on the transom.
Shouldn't be that much to it; carb, water pump, seals. There's a group that collects antique outboards in La you might find by fookbook. Those guys refurb them to look like new.

Thanks, I appreciate the input.
If I attempt it myself, I'll document and post pics.

There's really not much to those motors. Hard to put a price on getting it running cause never know what will need replacing once you get started, but sometimes a new set of plugs and a carb kit is all you need. Leeroy's Ramblings is the bible on older OMC motors, will walk you through anything you need to do.

Personally I think working on these things is a blast since they're so simple and tough. Pretty hard to genuinely mess up to point it can't be fixed. Parts do add up, but it's been worth it to me.

If it was running when it was put in the garage, it probably won't take much to get it going again. Maybe a few hoses that dry rotted and a carb cleaning.

NO need to rebuild. as other posters have said, just clean/ replace gas hoses and carb. i would put money on it starting. water pump may need some attention as well

I'd start with putting in the barrel like that one is, then take some mix fuel and squirt down the carbs, pull it a few times to see if it will bust off, and that should give you a starting assessment of what's needed next.
With that being said obviously look down the carb throat and make sure there are no dirt daubers or spider webs and check for any obvious problems. If it's sat all that time with no spark plugs yeah that would be an obvious problem.
If it's been sitting that long it will need a water pump impeller, carb(s) cleaned/rebuilt, lower unit fluid changed/resealed, and a good overall tune-up at the least. Not a lot of money and not real complicated.
NEVER EVER try to run a 2 stroke outboard on carb cleaner or starting fluid, always use gas & oil mix.

T-Mike's Vintage Outboard Restoration
I second Celltech's recommendation. If you aren't going to do it yourself, T-Mike is the guy. He can do anything from just getting it back running to a full rebuild including tearing the whole thing down to repaint every piece of it. Price ranges from $100 to I think around $5-600 for the full rebuild.
He got a 66' mercury 9.9 running for me that I use on a gheenoe for duck hunting with my son.

This is exactly what he did for me. I owe him about $300 in parts & labor when I go pick it up.

Just take off the carburetor and clean it real good I bet it’ll fire right up

My dad had one of those too! I thought I was big stuff when he upgraded to a 25.

If you decide to junk it, let me know. I might want it depending on how much you want for it.
Here's a few parts on ebay:
Water pump kit: around 25 dollars for the sierra kit
LINK
You can find cheaper coils but pay the extra for OMC if you need them.
LINK
If you need points/condensors, consider converting it to NOVA modules.
LINK
New fuel pumps range from 15 to 100 bucks, depending on quality/brand. You can snag a rebuild kit for about 20 bucks.
Pull the fuel lines and bring them to autozone, they will match them. If your plug leads are dry rotted they will match those as well. I think the plug leads were around 5 bucks each. I would try to start it before working on anything. You may be able to just change the fuel lines. They have a little membrane in the fuel pump that can dry rot, though. When I first started my 9.5 I had to keep pumping the bulb to keep it running. A fuel pump rebuild fixed that.
The hardest part was changing the plug leads, you have to pull the flywheel, unhook the throttle linkage, and then pull the magneto plate.
ETA: the parts I looked up are for a 1968 18 hp fast twin.
