"I have a 2005 F115 on a 24' pontoon. It normally runs 5200 rpm at full throttle. It has dropped to 4800 cold, and then when it gets warm it drops to 4000 and starts to miss until I drop it to about 3000. It has 450 hours on it and has always started immediately and run perfectly. I have done nothing but change oil in it."
 
"I changed spark plugs in it t

"I changed spark plugs in it today and it didn't change at all. I would really appreciate any help, there is not a yamaha dealer within 2 hours."
 
"pull your vst tank and clean

"pull your vst tank and clean the screen in the fuel pump, change out all your filters and pull your injectors and soke them in yamaha quality care carb cleaner dip, you mix it with water 1 part dip to 2 parts water soke them for 6 hrs or 2 hrs if you have a ultrasonic jewelry cleaner to put them in, after doing all the your motor will run like new, and dont forget to install a 10 micron inline fuel filter if you dont have one"
