Hello,
I have twin 1999 Yamahas OX 66s. The Port Side engine idles at around 800 RPM. But the starboard one idles at aprox 550 RPMS (sometimes at 600) . After a few minutes it goes down to aprox 450 and dies. Sometimes goes back to 550-600 and keeps running. I have the boat in the water now (not on the hose)
Is there a way to adjust the iddle speed on these 2 strole fuel injected engines? Pls send me a pic if you can.
thabks!
Lui
