Sounds to me like the idle air needs adjusted. Year model?

Yes start out by screwing each idle air screw all in then backout 1/2 turn. Run test and if needed back each screw out 1/8th turn at a time until best run test. Check all of the timing advance arm and linkage for free and easy movement. http://www.boats.net/parts/search/Yamaha/Outboard/2003/115TLRB/parts.html

Yes. Do all adjustment screws each time before testing.

If the air / mixture adjustment doesn't then check the synch.on the throttle linkages and plates.

I cleaned my fuel filter and started the boat and let it run til warm.and it never had any problems with hesitating. one thing i did notice is that the bulb was soft when i checked as i was loading up the boat.

any suggestions?
