Strange rattling, metallic sounds coming the the back of your engine, worse at idle, high eng. hours?? This is typically from the drive damper going bad.
Replacement Notes: Remove exhaust near trans, remove trans mount bolts to boat & drive-shaft coupling, loosen front pinion bolts & WD-40 pinion. Hoist rear eng. w/trans, remove trans, remove bellhousing, remove drive plate. Carefully choose bolt holes in new damper, attach with same bolts (Typically only 3 bolts used, original may have had 6) USE LOCKTITE on threads. reinstall bell-housing, apply spline grease, trans should slide easily into drive if bolted up correctly. Put back together.
WILL NOT work with PCM 40 transmissions with 15 tooth spline input shaft.
