First Post-Winter Ride: Stuttering Outboard

thinkxingu · 05-09-2021, 12:54 PM

Just picked up Boatie Two and, when we first headed out, the Mercury 150 outboard would stutter at 3k RPM. Over the next ten/fifteen minutes, I could get up to 4500 and, by that time, I'd filled the tank up with fresh fuel and was home.

Question: does this sound like bad/water in the gas (it was put in storage with 1/4 tank) or could it be tied to last season's battery issue (stalling when trimming down)?

The marina checked the battery system last week and didn't find any issues.
