2009 yamaha 225hp no power

[Ranger09]

The boat sat for a good 6 to 8 months and ran fine before I covered it up and ran a different boat. It had ants running all through it and water wasn't running through the pee hole so flushed the motor and run weed eater cord through pee hole and fixed that. Took boat out and literally not enough power to get even close to getting on plane. What to do and where to start first to get this working? Thanks, in advanced.

as always, start with compression, then test spark and the timing of that spark
if all of that is good then you are left with a fuel issue
posting all the motors model info would help others know what motor you are dealing with.
I would think this is an injected motor, so testing fuel rail pressure would also help.
along with cam timing to make sure it is good

everything needs to be in spec
