2003 48 Sedan Bridge
Engines
Cummins QSM11's
Recently bought a 48 Sedan bridge with 616 Cummings-2 1/2' shafts/ 28X32 props.
Notice more shudder than previous boat, a 450 Dancer 420Cats-1 1/2" shafts and 22X23 props.

This is only at a dead stop, does not appear when underway. Also the shudder is more pronounced in STBD/FWD and PORT/REV.

Recent yard work was new cutlass bearings, new props and shaft alinement check.


Have had other similar boat owners say typical agree?
