I have two 3126 420hp cat engines on my boat. The starboard engine is starting however it will not engage into gear. When I shift forward or reverse nothing happens. The engine appears to be running fine. As an aside, we have been without power in our marina for quite some time. Everything has been running on generator and batteries. I am thinking that there may be a relay or switch that is not engaging although I really have no idea. As we were planning on leaving on a trip today, any suggestions would be greatly appreciated.
