Yamaha Twin 150's

[samdog]

I have a Capehorn with 2005 twin 150 yamaha's. The starboard engine stalls when you ease the throttle foward. It usually is worse when the engine warms up. If you push the throttle down instead of easing it it doesnt stall. Also when running the engines are at different RPM's.

Do you understand what the model # is and where to find the model #'s on your motors?

The boat is about 300 miles from where I am at. I am going down there this weekend.

Re: Yamaha Twin 150's

there is an updated procedure to set the throttle shutters and TPS.
trust me this will solve your issue.
use the Yamaha marine dealer locator function,google it, find a dealership with a master tech and the issue takes 15 minutes to resolve.
