So, I got my baot back from the local Yamaha Hewes dealer and we loaded her up with a few days of gear for the weekend. Launched at Whittier and headed out. Boy did she run great. Got about 3 miles out and my starboard motor alarm went off and went into limp mode. I checked the battery cables and every electrical connection I could find. Everything is fine. When the motor is at running temp, it will not run over 2000 RPM before the alarm/limp mode goes off again. If I let it cool down for 15 minutes or so, it will run great for a few then back to limp mode. So, after messing around in Passage for an hour, I gave up and brought her home.
So, any ideas on what it could be? Bad voltage regulator? Oil pump? Some silly sensor?
