Location: Waconia, MN | I have a Mariner 40 hp Tiller motor and when I push the handle away from me to turn the boat, I have no issues. When I pull the handle towards me to turn the boat, it wants to stick a little bit. Not sure what the part is called but the metal shaft that slides back and forth as I turn feels a little tacky. The shaft is not bent at all. When I lube that shaft up, it slides back and forth just fine for a bit but then becomes a little sticky again, making it difficult to straighten out the boat after I have turned in that direction.
What type of lube or grease would you guys suggest I use to help this?
Thanks! |

Is there is a semi-circle kind-of bar that the motor slides along similar to the yamaha 2 stroke 50 with a little knob to tighten down as well if you want to keep it straight? I'm trying to picture what you are describing to see if I am on the right track about what could possibly be the issue...
Not sure if this could be part of the issue or not, but at least worth a check....
Just a quick thought here.. if you go to the back of the motor, see where the torque tab is set. If that has somehow gotten bumped, it can make turning one direction harder than the other.
Also, many motors have two grease zerks on the mid section of the motor. where the motor pivots there as well. If you have not given them a few squirts in while, that can add to binding as well.
In most cases, a motor turns easier one way as compared to the other due to pure physics, so things like the rear torque tab help to relieve some of that undue stress when turning the opposite direction.
Just a couple thoughts...

Location: Waconia, MN | I think you are on the right track, it does have a little knob that can be tightened to help keep the motor straight. I have greased it and this usually helps for a short while, but once again gets a little tacky and more difficult to turn after a while. I was hoping someone would have some ideas for a lighter weight oil or lubricant that won't dry out and perhaps be a little longer lasting. Thanks for the input Steve!

Location: Elk River, Minnesota | How about a dry graphite spray? Here is something you can try that might be able to do the same thing and hopefully not gum up with grit, dust, etc.
If you have a construction pencil (those big flat fat ones) you can do lubricate it with that. Clean the entire surface as best you can to eliminate any grease, or residue. Then, take the pencil over the bar. The graphite in a pencil is the same as what is in a dry graphite spray. I use this method on my wife's 9mm to lubricate the slide mechanism.
Does the knob have any sort of plastic or friction end to it? I wouldn't think it would be just a normal end to a screw as that would damage the bar. How does the motor turn if you remove the screw altogether or back it off as far as you can take it? Does it still bind?

Location: Waconia, MN | If I back the knob off all the way it moves much more freely, but might be a little too loose while navigating the boat. To be honest, I just got the boat/motor and haven't been on the water with it yet. I have only noticed this while moving it back and forth while on the trailer. In 40 degree weather as well. So it might not stick so much when the weather warms up. The guy I got it from did mention the graphite spray as well, perhaps the pencil idea isn't a bad one. Thanks again! |
