I am have an intermittent issue. 
When I turn my starboard key … no beep.
I tightened the wires on oil sending unit.
Replaced oil pressure alarm..

It worked for awhile..

Now I found I have to unplug a connection on the starboard side front of my engine. Not sure what this does.. but it gets the boat started.

Usually after a few days of non use or heavy rain. (Just my hopeful observation)

Any ideas of what could be happening?

I am assuming a loose connection or something is being re-set when I unplug?

Thanks
