I have twin 2002 Yamaha 200 HPDI. 2 weeks ago after running on both motors for a significant period of time the port motor's RPM's droped and the alarm went off. I shut the motor down and ran back to the dock with one motor. I replaced the oil filters and thermostats for both motors. This week when I went out I ran into the same problem but after the port motor shut down a few minutes later the starburt motor did the same thing. After shutting the motors down for a while they started back up and got me in. I had a mechanic look at the motors and he can't find an issue. Has anyone ran into this?
