Can the engine be saved after 3 months in salt water? (Glimt - Part 3)

We are trying to restart the engine after 3 months in salt water. It is a Marine Perkins Type: 4.236 from 1984/85. This series is about the salvage of a 70 years old Norwegian traditional wooden fishing boat named "Glimt", that sunk at the pier winter of 2018-2019. After buying a cheap fishing boat with my brother it sunk next to the pier last winter. The boat was not in great shape when we bought it - it was ready for a major overhaul. All the wood needed a touch up, and some TLC. We wanted to try her out the first summer, to figure out what needed to be done, and what we wanted to do with her. Should we restore it as a fishing boat, or more as a recreational vessel. We had some good times with here the first summer - before it sank at the pier. This is the story of her way back.
