Well it looks like the boat will not be moving for a while now. This past weekend I replaced the transmission fluid, hoping that might help resolve the shifting issue, as it was a bit low. Plus it needed to be changed as part of the break-in period maintenance.
It did not fix the issue, the transmission shifts fine into reverse, but will no longer go into forward at all. It is still under warranty. So for this and some other issues I contacted the installer to repair the issues. They are booked out til the 3rd week in July already, so it will be some time before the boat moves again.
In the mean time I work on some interior projects.
On a better note, the outboard did not get any damage from the quick dunk it took. It needed routine maintenance anyways and a small oil leak was found that will be fixed.
