1996 Mercury Mariner Magnum 3…on a 19ft bass boat

[Rob3xl]

Hello boating community heres the rookie of the year with a million and one questions about outboards.About 1 weeks
ago came across a sweet deal i couldn’t let go…. I bought a 1996 sprint 289 bass boat with a mercury mariner III 150 2 stroke.


I was wondering why I have to slightly put my foot on the gas pedal to get it started …and in neutral at idle speed dies specially while approaching trailer @ the ramp..

Slightly increase the timing or in other words bring up the rpm

LOOSE worn out gas pedal linkage ?
And or someone adjusted the linkage wrong ? Simple carburetor adjustments ?

disconnect throttle linkage at tha anchor bracket ... put in gear ta see if it acts tha same......... make sure tha throttle part doesn't move..

What maintenance of the hotfoot was done? What maintenance of the motor was done?

its also got an idle control module.. disconnect it first... it needs ta be throne away even if ya think its still good............

if tha throttle is fully closed (against stop and stop hasn't been moved) at rest and its actin' up it won't be because of foot and/or linkage
