140 4 stroke bogging down at full throttle

I am new to this form and am greatful for any help . I don't think anyone is a mindreader sorry if I did not give enough info. The engine has been well maintained . It sat all last year I was recovering fro an illness . This year when I tried to take the boat out it ran great until I tried to open it up then it bogs down . gas is new I have done nothing els . Just look for some advice as to where to start . Any input would be appreciated Thanks

were you running ethynol or non ethynol and did you empty and flush the fuel tank before refilling?

do you have built in permanent gas tanks or portables?

did you replace or clean all fuel filters? (good idea)

have you checked and or replaced old fuel lines and primer bulb? (if needed)

did you run any fuel system cleaner in it? (good idea)

Thanks for the reply I did not empty the tank completely I have a permeant tank. I will take your advice and clean or replace filters lines & primer and run a fuel cleaner . Its time to do that anyway . Thanks again for your input
