I replaced the water pump on my 2003 Johnson 175 and when I start it on earmuffs I get some propeller turn indicating "in gear". I was careful not to let shift rod turn but it seems like a small window of "neutral" to "in-gear". Can anyone tell me how to adjust the shift cable with the trunnion. The manual specifies to push and pull cable to determine slack and set to middle point but is not very clear. Can anyone elaborate. |

Robert,
Before you create a can of worms for yourself I would suggest the following.
“when I start it on earmuffs I get some propeller turn”
When you say you get SOME propeller turn what does SOME mean? It is not uncommon to get propeller rotation on the muffs in neutral because of drag produced between the gears and the propeller shaft; a result due to the viscosity of the gear lube. With the motor shut off and the remote control in neutral you should be able to easily spin the propeller by hand. If so, you are in neutral, if not you have a problem. |

On some models, there is as much (almost) as 180° of play due to the alignment of the shifter lobes on the clutch dog and gear.
(Centering Shift Linkages - Manual)
(Joe Reeves)
The engagement of forward and reverse gear must be evenly set. The shifter dog and the gears both have what is called lobes. The lobes of the dog must be side by side with the gear lobes in order for the dog to engage one gear or the other which results in turning the propshaft.
To grasp this scenario, with your left hand form a "C" with your thumb and forefinger. Now, with your right hand, form a backwards "C" with your thumb and forefinger. Your fingers will represent the dog and gear lobes.
Slide the finger and thumb of your right hand alongside the thumb and finger of your left hand so that they overlap. This is the position of the dog and gear lobes when properly in gear.
To have the gears adjusted so that they engage evenly, it is best to have those lobes set so that they butt up against and face each other.
To visulize this, butt the tips of the finger and thumb of your right hand up against the finger and thumb tips of your left hand. This represents having the gear and dog lobes directly facing each other. Should you atempt to force the engine into gear with this condition existing, damage to the shift mechanism will surely ocurr, so keep in mind that this is just for adjustment purposes only.
To obtain the above adjustment position, spin the propeller while shifting into forward gear (lobes alongside each other). Now, shift into neutral and turn the propeller ever so slightly to have those lobes face each other (1/4" would do it), then move the shift lever back into gear but only as far as it will go without forcing it.. Adjust the shift lever/linkages so that this point of engagement is half of the shift lever's travel. Now, do the same with reverse gear.

an amount,..of propeller roatation,can be considerd absolutely,normal...if it appears,to be 'powered',in gear,...more research is warranted......thickness,of cold oil,on a flushette,can ,and does cause,prop,rotation,..depending on the wear,hrs of use,..etc...before u worry too much,make sure,it is powered,in gear,...a 2x4,is just the ticket.....if u can stop it,no prob,if it slams the board,...something,'aint' right.. |

Thanks to all- I just didn't remember the prop turning in neutral. With engine off and in neutral prop turns with ease, so I guess there is no issue. I just thought that the neutral postion had moved minutely from removal and reinstall of lower unit. thanks again. |
