Sunspot Baby is a 1994 Prout Manta
with two Volvo
2003B engines and sail drives. One sail drive (port side) sometimes does not want to shift into forward gear
. Two years ago the sail drive was disassembled and $800 in parts
were installed to fix the problem. Something about a “cone clutch”. At that time the old parts
were not visibly bad but, of course, they could have worn well outside of tolerance and not look bad to the naked eye.
The problem never went completely away but occurred much less frequently. Now it is occurring more often. The gears eventually engage, sometimes with a bit of a clunk. Revving the engine
up a little helps, thus the clunk. This happens more often when the engine
is warm, like when maneuvering to get back into the slip, but may happen when cold.
Drives are serviced annually; oil
is full, clean, and clear.
Does anyone have knowledge of a specific fault that would give these symptoms?
The starboard engine, same age and hours, does not exhibit the same problem.
