I have a '99 340 dancer with 7.4 merc spinning velvet drives.. Last year I noticed what I thought was maybe just cavatation when revving up to 3500 rpm from 1300 rpm over a period of 3 to 5 seconds. This season it has happened more frequently. "it" just sounds like a little bit of thummping, port engine revs about 1500 r's more than s/b , sync gauge wacks out, and may best description of this is . . . " kinda feels like the clutch is slipping". also this season I must rev up from 1300 r's to 33-3500 rpm over 15 seconds which affects my get up on plane time time.
Any Thoughts anyone ??
