From everything I have heard and read Deere makes a great marine engine. On the other hand Deere is often talked about in any discussion of right to repair issues. The talk is mostly about farmers not being able to repair their tractors themselves because diagnostic and repair software is not available to them. I just retired but the last few years I spent a lot of time speccing a new vessel for Glacier Bay National Park. The contract for the boat has just been awarded and Deere engines have been chosen. At this point I don't think they are locked into one particular engine brand though, it probably could be changed. The park does all their vessel maintenance in house. They have a very good marine mechanic. The park is isolated though and a Deere technician if needed would have to be flown in. Probably all new engines are computer controlled these days and require software to diagnose some issues but some makers might be more willing to let owners use the software.
