'11 Mercury 115 4 stroke bogs down

[Triton06]

Have some problems with my motor...Cranks fine...idles fine...put in gear & it idles fine...runs top end fine...the problem is when u throw the gas to it to get out of the hole the motor bogs down & shakes...like it is running out of gas...sometimes it will catch up & get up out of the hole...sometimes you have to start over...sometimes the buzzer will go off but it's not storing any fault codes...had it hooked to computer showed no fault codes...fuel pump...coils...injectors all checked out fine...gas lines...fuel filters are all new...any suggestions...

This is a custom built Scandy white tunnel hull...hydraulic jackplate...spitfire x7 19 pitch...this problem just started 2 weeks ago...it does it at the beginning & when it's been run a while

Do you have PRINTOUTS from the Computer Diagnostic System (and/or recordings with the CDS, when the engine is doing this)? Would be interesting to watch the MAP data...

WARNING HORN "BEEPED"

It was the throttle position sensor...

My 250 is doing the same thing. I can't get it out of the hole just started yesterday. How did you find your issue?

[Triton06]

Had to hook computer to it and go to lake to run it..it had built a memory in the sensor...if I threw the hammer down it wouldn't do it...if I eased into it would do it at have throttle...

"Sensor that's failing within range" (often does not cause any fault, just a related performance problem).

Bassmaster 6548... good idea to open a SEPARATE thread on the 3L Forum for your engine (one engine per thread, in the appropriate forum).
