You guys are awesome. Thanks so much
Ive got alot to do to figure it out now. I will update when i can to see how it all goes.

I really appreciate all the help! Id rather do my own work and learn along the way, and you guys make that possible!!

0D267943 is the serial number . Ill be checking it tomorrow. Im going to bet between that and the cheaper oil are my two issues

0D267943 is the serial number. Ill be checking it tomorrow. Im going to bet between that and the cheaper oil are my two issues

The other i seen locally was the Johnson oil. But i can look for something better if thats not the best either?

Thanks for the info. The boat is new to me so i dont know what oil it has in the tank so ill get some full synthetic and get new gas in it. And see what it does after that. Would Yhe quicksilver synthetic be a good oil?

Ill find a spark tester like that to test coils also once i get the rest going

So if a coil is going bad that would make the oil not burn all the way witch would make it smoke more is what your thinking?

Eyeball it. I suppose ill get a tester for better results. But the spark was very good looking. But id like to have it all working properly so ill pic one up. Any certain tester i should get? Something from a auto store ?

When its running, it runs great. Nice smooth idal. It just smokes more than it should. Not sure if the oil injection is putting in to much to fast or . I do know i got old gas in the big built in tank that i should probably just drain out and replace

They were a bit wet when pulled. But spark was very good on all 4.

Thanks. I did just do a full carb clean. With all new carb kits.

Im new to fishing electronic. So i have it on the settings it came on out of the box if that helps.

Like i said , normally the screen is all full of blew from 0 ft till bottom.

Well i got that part from Ebay. Thanks for the help iowaboy1! And got it all back together, and took it out and ran good. Thanks all

Thanks !! Ill give them a call tomorrow and go from there if not ill give that one a try

So my bad luck just got worse. When putting the carb back togather the lower carb screw that holds the bowl on broke on me. No were on line has them and they do not make them anymore. Also could not find anywhere that had a bad motor with parts i could take. Im at a complete loss of what i can do

Thanks for the info guys! Really appreciate it.

So my horn does not work. Ill assume thats what beeps for the motor? I dont see were the horn is located on my 93 alumacraft dominator cs.

Im 1 hr south of mpls.
I do have a carb kit on the way. The seal to bowl on the carb was breaking up and had bits all over in the bowl of the carb.

How is the oil injection on those motors. Should i keep it that way or switch to mix gas?

Also can anyone tell me if the motor itself has an alarm for issues? It never beeps even when turning the key. Wondering if its not working or does it only beep if there is an issue.

Anyone know were to get 2 carb kits for a 1993 2 stroke 40 hp mercury? Im having a heck of a time finding them

Here is a picture

Its coming out the bottom of the bottom carb. It looks like a silver rod with a spring type peace on it. Right next to the bowl.

The top carb has a peace on that part that goes to the bottom carb

I also just noticed the bottom carb has a little leak. Would that maybe be the problem?

Its a 2 stroke oil injection motor

Its a 40 horse. Model vj40tleia not sure how to tell if that model had a pump or not

Found a new boat i may look at. It has a 91 Johnson outboard on it. They say it takes mixed gas. Any input on this motor? The good or the bad about them?

They were asking 3900 for the boat. Not sure what he plans to do. All i know is its at a shop waiting to get checked to see what happened. Or what it need.

Ok thanks guys. Dont sound good. Not sure if he will have it rebuilt or not. But im not sure if id buy it if it was. Or how they are after a rebuild.

It had oil injection.

It was in neutral and it is not a tiller. Its a 40 horse motor. Sounds like its worse then they thought. We were going throttling up and it just died. So i would assume now that the motor is locked up.

How do motors do after a rebuild if it gets it done? Do they last or is it not worth the cost?

Thanks guys.
