I have a 2008 Honda 150hp that I bought new, is under warranty, and is OEM maintained annually. At some point in the season at full throttle it stops revving to 5500 RPM instead when at full throttle it revs up to 4000-4200 and sits there (Boat at 18mph). And then sometimes woosh it will spin up all the way to 5500 rpm (Boat at 32mph) and stay there until I throttle down. I may or may not rev back up to 5500 rpm again on the next acceleration. It is bizarre (Also bad for towing skiers and wakeboards). The engine starts and runs - no problem. The only issue is the rev to full throttle and missing the power curve that comes at full throttle. The difference takes the boat from 18 to 32 mph so it matters a lot.
Any ideas on what might cause this?
Do you think it is fuel or engine/engine tuning related.
THANKS.
