That time of year, again.
The initial shake out run.
Changed all oils last fall, changed fuel filter.
Last year, boat was stalling out on top end.
Removed ball in fuel tank check valve, it seemed somewhat restrictive.
That seemed to do the trick.
Was sputtering, then gaining rpm on top, after that.
Went and checked spark plug wires(new set last year),wire nearest stern on the starboard side was not seated, re set and boat ran quite good for four days.
Hope all a great boating season
