Recently while out with a friend my force 120 started giving me some trouble. After running the boat at about 30mph for a few minutes I dropped the engine down into idle speed. After about a minute a clicking noise came from the engine and it died. I tried to start the motor back up several times and had no success. About an hour of letting the motor sit i was able to start the motor with no trouble. Again once running the boat for several minutes the same clicking noise was heard and the engine died. Any ideas on what might be going on??? (When taking the cover off the engine in attempt to try and see if there were any obvious problems I noticed when pumping the fuel line bulb and trying to start the engine gas was leaking from the carbs). Any help is greatly appreciated

Thanks

Re: HELP.. 95 force 120 shutting off

At the time I did not check the plugs... but since then I have tried starting the boat hooked up to the water hose to see if in idle i get the clicking and shutting off of the motor. However I have been unable to start the engine up again and YES the plugs have been soaked. I wonder if this means the fuel is not flowing through the carbs properly?. (The engine is turning over with no problem, just does not seem to be firing, not sure if there is not a spark or fuel is not getting somewhere or what. I do not really know that much about what I am doing and I am new to all this).

Also I am unsure of what RPMs I was running at. Just pretty sure that when it cut off on me I was close to or at Idle speed.

When your engine is giving you trouble at idle (which i hear is a common problem for Force) are you getting the clicking noise?

The only thing I can think of that would click, is a relay or a solenoid, and you would not hear them over the noise of the engine.

This is very unusual in my opinion.

Just a silly question ,but you do have oil mixed in the gas ,right? You may have an internal [or mechanical] issue that as the motor heats up ,it rears it's ugly head.It could be a ring hanging up on the transfer ports ,but usually you would see some melted aluminum [from the piston] on the plug. I have run across water intrusion causing the piston to try to lock up due to lack of lubrication, and these particular force motors[120 h.p.] have a bad problem of cracking the exhaust plate A good look at the plugs for water and /or aluminum, plus check the compression on all the cylinders and post the results.As to the force motors having an idle problem, these motors were designed to be run in the upper rpm's more so than at idle and they will have more of a tendency to foul plugs,but fat [rich] at idle is safe on the top end ,so ,to me it's a good trade off [just keep some extra plugs,or don't do a lot of idling.If you don't mind doing your own service ,these motors are a great bang for the buck!Hope this helps and like I said earlier keep us posted on what you find

Also something else I thought of, if your leaking fuel ,you might be running it lean, which will destroy any make of motor,so get it checked out sooon:eek:
