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. Also when you just run the starboard engine it barely pushes the boat, nothing like the port engine. I would appreciate any help, it has been in the shop twice & they did not fix it.

It's usually a fuel problem, if it's a carb model may need to clean carbs and sync.

It is fuel injected & one engine runs fine.
