View Full Version : Outboard tune up

01-01-2011, 10:19 AM
My brother left a canoe with an old 1.75 hp outboard (gas) up here for me. Hoping to use it on the Clinch and Holston, maybe the lakes. Motor starts, but runs very rough. Anyone have any recommendations for where I could get the motor tuned-up? Thanks in advance.

It would probably be worth your wild to learn to tune it up on your own...(?) Well, if you are trying to save on expenses. Most shops charge around $70 an hour to look at a motor. A tune-up would probably run you around $150-200 with parts. You can do it for about $30-40 and have a better understanding of your motor in case you have issues on the water.

Check out this link.

It will give you a good idea on how to tune up your motor.

*I am pretty sure that motor will have some carberator gunk in one of the jets. Every motor gets them by sitting just a few months. It will cause your motor to idle rough and to not hit wide open throttle.

Start by taking the carb. off and soaking it in cleaner over night. Be sure and take all the needs out and see if you can see light through the holes. You will probably see a dark - gunk obstruction in the back of the holes. Be sure and blow those out really good. Put the bottom plate back on with the carb. upside down and make sure the float rests level.

Reseat all of your idle needles and be careful not to over tighten them and cause damage to the tips. [Put the idle screw back in the number of turns you counted taking it out. If you have forgotten how many turns, screw it in until it bottoms and then turn it out 1 3/4 to 2 turns. That will be close enough to get started.]

Be sure and get a small gas tank. I would never get more than a gallon of gas per trip and mix correctly. Gas will foul after a month of sitting and run horrible in your motor.

Here is one of the best links for information about motors and the boat parts are fairly priced.


Hope this helps...

Thanks Shawn. I was hoping you'd chime in. Not sure this motor is worth $150-200. I'll give it a try. Thanks for the links.

If you cannot get it running ok after your efforts; you are welcome to drop it off at my house and I will give it a good look over and see what I can do to help... No charge!

Just ask that you would give back to someone else when you can:)

Remember, if any boat is under power, it needs to be registered. Does it have the registration on the bow? You might be able to get it transferred to you. Call Boating Registration at TWRA, 1-615-781-6585 if you have any questions. Good luck on the outfit and good fishing!

Not registered in TN yet (brother lives out of state), but will be.

Will definitely "pass it on" Shawn.
