My neighbor at the lake has A 1999 Rinker 242 with a 5.7 Carb engine and a Bravo 3 outdrive. This weekend it decided to became hard to shift into gear. We disconnected the shift cable where the upper and lower cables connect and determined it was something in the lower cable or drive. Does anyone have the service manual for the Bravo 3 or can offer ideas what might be the issue.
