I recently bought an used Honda 90hp from 2000. A month ago a little piece felt of leaving a dent/hole on about 1x1 cm. The hole didn't go through the extension case. Properly the engine had a bad repair by the previous owner (I will deal with him later


).
Yesterday I wanted to clean the little hole to get it repaired. Then I realised, that now the hole go all way through the extension case with a small opening on about 2x2 mm.
My questions are:
- is it repairable? Can a pro weld in the extension case?
- is it a problem if any water have entered the extension case? What is on "the other side?
Hope you can help me - and calm me, since we have planned to bring the boat on our holliday in 2 weeks.
The attached picture shows where the hole is placed.
Thanks
