2002 yamaha 25hp, more power???

I just got a pontoon that has a yamaha 4 stroke 25hp on it.
Anyone know if it would be easy to kick it up to 30hp?
It's a f25tlra

I tried to find out the exact same thing a few years ago with no luck... Good luck..

There's no conversion mods for the F25. Most of those motors are 'over propped'. If it's on a pontoon, you should be running the lowest pitch prop available. Probably a 7p. Other than that, it's a pontoon.... and a 25hp, don't set the bar too high in expectations.
