Adjusting idle and air fuel mix screw on a MerCruiser

[@barrybebenek8691]

Nice work. But…I ‘believe’ that how you did this (which is correct), is supposed to be adjusted while under-load and in the lowest forward throttle (prop running obviously). 👍🏼🇨🇦

I know it’s an old video, but just wondering was boat running good after your adjustment..

[@nuiquist]

[@nuiquist]

your aiming for highest achievable vacuum with a smooth idle

[@falconeaterf15]

Idles great in neutral, drop it into gear on the water and I bet it stalls.

[@nuiquist]

I am using an automotive volts meter and it is hooked up to the number 1 spark plug wire.
