Thread: older Evenrude Two stroke engine help/ Advice

Just remember that motor has a shear pin in the propeller an get some extras before you hit something. A nail or a piece of wire coat hanger doubled over will work in a pinch, but will start to ware the slot in the aluminum wheel. If I remember correctly Michigan Propellers makes a brass or bronze alloy wheel if you cant get the aluminum one rebuilt to the correct pitch. Hearing that name Fastwin 18 brings back some fond memories. My Dad upgraded from a Wizard 12 to the Evenrude 18 on our homemade wooden skiff, I can remember that like it was yesterday.

That's old gas in the bowl. More than likely you'll have to replace all the hoses,replace gas filter,rebuild carb,look at the recoil, check the points by pulling the flywheel and replace the condensers as well,replace lower seals and water pump. Also do check the the compression before you spend a lot of time and money.Good luck with your project.

Thank you fishingman...and Skippa Chippa...I hope to make a bunch of memories myself. Fishingman, I might end up taking it to someone a bit more qualified to work on it than me...but I will be checking the compression my self before hand. thanks again. Eric

Outstanding engine.
My late Dad bought a 1957 18 HP Evenrude Fastwin brand new, ran like a champ for years and years. He also had it's "Little Brother" a 7.5 hp Fastwin, also excellent. Someone stole the 18 about 10 years ago. Get it running, you will be glad you did.
Yep, you need to get some good shear pins. Dad worked with some men that made their own out of brazing rods, Dad had a bunch of them - and we went thru them, darn thing shear too easy. I recommend you find good shear pins.
We always ran it with the foot unlocked (Unless we needed reverse) so the motor would fly up when we hit something.
I still remember the old gas tank, too. Pressured up with the thumb button on the tank. Rough on the thumb, but effective.
Every time we would come in from fishing, we knew just when to disconnect the fuel line so the engine would run out of gas just as we coasted into the boat house. We did that every time and went years with no problems.
Water pump impeller replacements are easy enough, keep check on it.
Jet adjustments right there on dials at the front of the motor made adjustments easy, that thing would wind up nicely on plane.
And don't be stingy with the oil, they love the oil.
Good find, good luck with the motor!

Thank you for the info and the memories Grand Pooh Bah. Not sure if this one needs that pressurized tank or if it's been converted already, as The fuel fitting looks like a modern one. we got some more snow last night, seems ol' man winter doesen't want to go to bed this year, I will get back over to the shed and get me some pic's of that and find out. Not sure where to get one if it does as I didn't get one with it. they said the fuel line and tank were shot and they got rid of them...gonna make things interesting for sure. Thanks again. Eric.

Your third pic showes the fuel pump that is going to be a single hose tank. You can get every thing you need for the gas tank at Walmart if you choose.

I had a '56 18hp twin with the split aluminum cover and a double fuel line. Ran like a scalded dog on the 12' sears boat I had it on. Very simple motor but the lower unit is different than any I'm used to working on. There is a round rubber string seal where the skeg/cap goes back on that can be a problem leaking water if you don't pay attention when putting it back together. I had bronze and aluminum and stainless shear pins for mine, they were readily available back then. Aluminum for trashy area, bronze for most everything and stainless if you were a brave man and didn't mind knocking the blade off of a prop, or damaging gears. Sold it years later after at least 5 or 6 years of flawless service. Heavy and ugly but what a beast. You had to be tough to pull start that one. I later had a 35 Evinrude that was easier to pull. I used to outrun 40 and 50HP trihulls with that little 12' boat. Many great memories.

I used a cut to length 16 penny nail a lots of times in the old motors as shear pins. Those old Evinrude 2 cycle motors are tough for sure.
