Force OB smoke when idling

[pecheux]

Hi Y'awl,
We all know Force motors smoke more than other OB's ... especialy idling (trolling) why I dont know since all seems normal at Wot. My question is this: any chance using a hotter spark plug would solve part of that problem ? (obviously without overheating the motor)
Tx

Re: Force OB smoke when idling

It will still smoke just as bad.Use a better quality oil and it might stop some of it(probably not).
The old outboard oils were actually designed to smoke and carbon the rings causing failure. Then they got tired of people complaining and started working on the additives and ended up with TCW-2 then TCW-3
I had to rebuild both of my motors twice (twin/85/1988 Force)because of the rings siezing. Since the TCW-3 I haven't had to touch them.
Every year run a can of Power Tune or Seafoam thru to break up the carbon deposits. Jerry

Seafoam is GREAT for cleaning out deposites but be forewarned- if you think your motor smokes now, you ain't seen nothing yet!!

This 15 hp OB has burned less than 10 gas tanks ... altough trolling 90% of the time ... I dont think there is much carbon in it ... I checked the plugs and they are wet but without any carbon build up on them. Using synthetic oil (Amsoil Hpi) already ... best anti smoke was using Amsoil Saber at 100:1 but as little smoke as there was the exhaust stinked and irritated my troat ... next step would be to install some sort of 12 volts fan that would blow air right on the engine towards the rear of the boat ... thus blowing the smoke away from me ... that may be a spring time project. LOL Tx for your feedback.

I'm seeing the same smoke symtom as yours. Mine is an '88 15HP also. Just got mine running after sitting for 10 years. The little thing generates smoke like there's no tomorrow. I'll try TCW-3 and will post back on the results.

Re: Force OB smoke when idling

TCW-3 is outboard oil Two Cycle, Water cooled, revision 3. Buy it anywhwere you buy outboard oil. Any brand you prefer. The container will be marked: meets all TCW-3 requirements. Do not try to use multi-grade automobile engine oils in your outboard. The multi grades (10W30 for example) have additives harmful to outboard engines.
