It appears that the engine coupler has failed on my 1998 454MPI bravo combo.
the outdrive input shaft does not turn when the engine is running.
From what I have read the engine & outdrive need to come out to replace it.
what is a reasonable labor cost for this job.
the boat has 400 hrs. should the gimbal bearing be replaced at the same time?
I noticed a vibration when changing trim under heavy load. was this a sign that the coupler was going?
