My Yamaha 225 Four strokewhen i am running around 40 mph it runs good but when I try to run over that is sounds like i am running out of gas and then I back back down and it runs fine. I have changed the water seporator and the fuel filter and, I just found out there is another filter on the top of the motor. I am going to change that. Does anybody know of any other reason it would do that? Trying to save from bringing it to the shop because everytime I bring my motor to the shop in the past(not this one is the first problem) they never fix the peoblem it is any doind the same thing after I spent a lot of money.
Thanks for the help.
