Yamaha 60hp FS Mods

[quick2008]

Hi Guys

The 20hp 2cyl yam 2 stroke can have modifications to make it a 25hp.
The 40hp - 50hp 3cyl 2 stroke, same concept
Wondering if anything "simple" can be done to a four stroke Yam 60hp 2007 for performance gains
Exhaust or intake?
Engine is on recreational 4.75m aluminium hull, so not looking for "race" mods
Just dont know much about FS outboards so just putting the question out there
Any help appreciated

Cheers :)

set up and propeller is worth more than engine modifications remove weight also, small foot or big foot
