Hello, my name is***** will assist you.

You will need to adjust the shift cable going to the drive. It has stretched and just needs to be realigned basically.

Customer: replied 1 year ago.
I forgot to mention that it engages in reverse properly? Also is stern drive oil the marine equivalent to automatic transmission fluid? Could this be the issue as well?
Customer: replied 1 year ago.
Does the boat have to be out of the water to adjust the shift cable? Will I damage the transmission operating the boat prior to adjusting the shift cable?
Expert:  Charles replied 1 year ago.

No, the boat does not have to be out of the water. Yes you can damage the gear housing shifting when the engine revs are high.
