Used Outboard Motor
Posted on 2/20/20 at 12:49 pm
Posted on 2/20/20 at 12:49 pm
Just looking for knowledge regarding smaller used outboard motors. I've owned a 9.8HP 4 stroke Tohatsu, a 15HP 4 stroke Mercury, and a 25HP 4 stroke Yamaha. I didn't have any problems with those three brands. There were all used when I bought them.
I'm currently looking to buy a used 40HP motor. Odds are, based on the year models I've been looking at, it will probably be a 2 stroke. I don't have any experience with 2 stroke motors or engines other than my weed eater.
It'll probably be a motor manufactured between 2000 and 2010 or 2012. Please give me your thoughts on what you have experience with, what I should stay away from, what to look for internally, etc.

Just to start
Look for crazy shite like weirdly crimped wires, stripped nuts and bolts and cracked or peeling rubber parts.

If I were in your shoes I'd hold out for a 3 cylinder two stroke yamaha, and I'd look for good compression and signs of corrosion. Unless paying next to nothing, have the seller run it on the water and verify it runs through the whole rpm range. If they say it just needs carbs cleaned, tell them clean the carbs then.

I'm supposed to meet with a guy selling a 09 Tohatsu this weekend. The plan is to run it on his boat. I also have a compression tester I will bring with me. I have absolutely NO interest in anything someone says "it probably just needs XXXXXX cleaned" or "XXXXXXX" replaced. If it doesn't run perfect, then I'm out. I will be sure to test the motor out before agreeing to buy it, as I've already bought 3 used motors in the past, but just never a 2 stroke.

Merc 40 3 cylinder is the best small hp motor Ever built. La sportsman has one for $3,500 if it’s still on there. Easily hopped without wrenches (add 60 carbs), reeds and will smoke compatible 4 strokes. Add wrenches and it can become an 80+ hp drag motor with filler handle.

I saw that one. I'm also in negotiations with someone with a 2000 Merc 40HP for about 3k. I believe the one you are talking about was previously rebuilt, which is something I'm trying to stay away from.
Whats yalls opinions on the Honda outboards? I was told they are solid, but slower?

My brother has a Honda and he loves it. He has it on a light hull and he always talks about it having a lot of torque. He has never complained about the speed from it but my brother has never been one to do anything quickly.

Good to know. I don't know anyone who has owned one which is why I was asking. I've always been a fan of almost everything else made by Honda.

When buying find out what brand oil has been used when mixing in the gas. Most mix at a rate of 50:1. Only use ethanol free gas, add 1 ounce of seafoam per gallon, and always run the engine out of gas before allowing it to sit up. I've an older 2 stroke Evinrude 30 hp. The only times I ever had an issue was after allowing it to set up after using ethanol gas. After replacing fuel lines and carb kits a couple times I learned my lesson. Ethanol free gas, seafoam, and running engine til empty. Haven't had an issue since.

Good info, thank you. So I assume 50:1 is the typical ratio? What about motors that have the injector deleted? Should I stay away from those?

I would. I prefer to mix the oil in the gas myself. If teh injector goes out or isn't working properly it could damage the engine. I use the Supertech TC-W3Outboard 2-Cycle oil. 50:1 is 16ounces to a 6 gallon tank. Add 6 ounces of the Seafoam and run it. The seafoam will stabilize the fuel and keep the fuel system clean.

You mean you wouldn't stay away?

I would stay away from those with injectors. A used outboard where YOU mix the oil into the gas is the way to go.
I'd stay away from the old Mercury brands. The newer models are good but back in the day Evinrude, Johnson, Yamaha, and Mariner were solid. Some of the Mercury's had so much compression that a manual rope start one would jerk back so hard it nearly would break your fingers.

Nope, wouldn’t buy a used Honda. Would make sure LU seal is solid since a new LU is $1,500 don’t ask. Think Jerry’s still has the 50 carbs, bolt on and it will run like a spottedassape but be thirsty.

I'm not sure what you just said....

had an ‘04 40 merc on a 16 ft xpress. gave the rig to my son. never had a problem and he’s still using it.
Posted on 2/20/20 at 5:28 pm to Homey the Clown
Prop seal can and will go bad allowing water into LU frying it. Older motors should have any seals replaced that contact water that includes o rings. Other than a LU and stator mine was trouble free and I ran the shite out of it monthly.

Im looking at a few in that year range. A 2000, a 2003, and a 2006.

All the obvious stuff compression bad spark on one of the coils, only thing I really know from running these things with my buddy is that the oil distribution system can be faulty and easily bypassed by just unplugging it. If dude is hooking the motor to a fuel can that is already mixed then that means the oil well under engine cowl could be busted... that can blow up your engine by running to rich or to lean. It may be easier if your on a smaller boat and only need 2-3 5gao fuel cans and just mix as you go. But if your having to mix a larger boat fuel tank in the 35+ gal range I would have issues with that and I would need my oil resivor and feed pump to be running well and not be worried about it. If im running small fuel cans in the boat I have zero issues with a 2 stroke having the oil resivor/oil feed pump pulled to run it on mixed oil straight from some Jerry cans in the boat.
You prob already know this but it's all I can really contribute

Did you find something? I decided to switch over to a synthetic 2 stroke oil made by Lucas. Academy has a great price on a gallon jug.
