Hi All,
noticed yesterday my 2019 Merc 25HP 4S EFI was not getting full throttle, has only 20 hrs on it so I doubt it was a cable stretch issue - more like not done properly from the factory and obviously not checked during the delivery or first service.
Anyway, I adjusted the throttle cables and now WOT has gone from about 80% to 100%... It made nearly 200 RPM difference at WOT which would equate to a HP gain as well, it improved the holeshot, noticably!
Check yours today!
