I have a 40HP Mariner 6E9 engine and it runs very well up until high RPM'S at WOT and bogs down, I observe that when I put it into gear it moves a bit, the linkage to shoves the magneto linkage moves up a small bit( fully advanced in youtube video below) and it does not continue to move as the accelerator or throttle is increased to WOT. IN the video I have included it shows the boat at full throttle with the engine off, what I was wondering was if it( timing/magneto linkage) did not advance enough at high RPM'S could this cause it to struggle and stutter at high revs. Could do with a few opinions thanks. Basically I think its not in sync Thanks
