Re: e-Tec 90HP 2009 - coughing at quick RPM increase

Would you please explain it further than just no? How could the gear be in idle mode if the motor is performing movement of the boat?

 

Don´t get it? And it always start to work  would when engine is heated up after 5-10 minutes... don´t understand how this switch would cause that behaviour?

 

Really intrested in more information, please enlighten me!

 

Thanks for your support

 

Best Regards,

See post 4 by rickmcd53. Sticking switch does not mean stuck switch. It could just be lazy.

 

It may not be the switch, although everything points to it, but it's impossible to do any more than make suggestions based on all together hundreds of years experience between technicians here over a keyboard.

 

To eliminate the switch: first start motor, then disconnect the switch with engine running (It has a quick connector, sometimes hidden under VST ) and test engine.

I will for sure tear it apart and test as you propose. Thanks again!

Perhaps another explanation would help.
The engine shifting mechanism is mechanical levers that physically shift the engine in and out of gear.
The gear position indicator switch is an electrical input to the engine control module which let's it know that the mechanical lever has moved. Gears can be mechanically engaged and working but if the control module doesn't know it is in gear then it will limit engine speed.

Thank you so much! Then I understand it much better! Make very much sense! I´ll check if I can look at it this week end!

 

Really appreciate your support!

Switch verified with multimeter, working ok. Really thought it would be it when I found all that greeze in there Smiley Happy

Any other advice is much appreciated.

It's not the control box one. It's the one next to the control cable connections on the engine.

Oh.... I didn't understand that. I thought it was on the gear handle itself...

 

So the one we are talking about is a mechanical thing that is pusched inside the engine to activate an electrial switch?

 

Than I need to check again! Should be number 8 on the picture? Thanks!

It's number 14. Use 'Throttle and shift linkage' page for clearer picture of  position of switch.
