When I recently purchased the boat I cleaned the points on both engines and both ran strong. I was told the V-drive on the port side was bad and only the starboard screw was turning. The previous owner told me the v-drive is bad and the port wasn't turning. This made for an interesting passage from Venice, FL to her new home St. Petersburg, FL. The port propeller turned during the passage so I know it's not stuck below. My question is this a typical item that breaks? I've been told these v-drives are pretty rock solid. My question is will this be a fairly costly repair? Do you think it could be the transmission and not the v-drive? Thanks in advance for your thoughts.
