I am getting a loud pitch alarm when I troll at low speed; when I throttle up it goes away after a few minutes and I don't notice any performance change. Only thing I notice is perhaps a little less exhaust water discharge from the rear of the engine - help!
my 2000 yamaha 150hp is spitting oil/gas out of the exhaust, esp at start. the motor runs great and the problem seems to go away (although not completely) as the engine warms. I'm about to have the boat winterized - any suggestions?
