Can't free throttle

Hi,
On my sailboat, I have a 3ym30 yanmar (2013). Everything works except I can't pull the nob on the throttle to lock the throttle in neutral position (to rev the engine in neutral). Foreward and reverse works with no problem.

Any idea how to troubleshoot this?
THanks

Re: Can't free throttle

Can you post a picture? On the vetus type with a small push pin for neutral, it's has a rubber pencil eraser covering that breaks down and can jam in or out. It took a pair of tweezers to pull the disintegrated mess out of or off the pin that's suppose to go in to make go into neutral.

You can rev the engine in neutral directly on the engine.

Re: Can't free throttle

Attached photos. I am wondering if I should start by removing the screws (red arrows).

Thanks

Re: Can't free throttle

The knob may be stuck with old grease and grime.


Open up the kit, clean it, put it back together. Works now?


Eh ;-)


A temporary measure is spraying the knob with plenty of WD 40 so that the liquid gets well inside the knob/housing gap. Work the knob. This may dissolve some of the grime.

I unscrewed the screws on the outside knob but the knob wouldn't come out.
when you say "Open up the kit, clean it". Are you talking about the screws in red (in the picture)?

Thanks

Re: Can't free throttle

Sure you don't push it in instead of pull it out? On many, if not most, sterndrives and outboards with single-lever controls, that's how they operate.

If not, see if you can get the little flat head screw at the base of the lever out, and see if that lets you unscrew the lever. Once you get the lever out, that should let you remove the exterior bezel and perhaps either free up the knob or give you acess to remove the complete control and clean it up off the bulkhead.

Yep. True.


Typical Volvo / Tfx is push in.
Typical Perkins is pull out.
