Buongiorno a tutti. Sto guardando una Grady 330 express bianca anno 2010 e vorrei alimentarla con un paio di Yamaha 425'. Se la barca fosse del 2022 non ci sarebbero problemi… ma questa motorizzazione non era prevista per il 2010 (coppia max 350). Qualcuno sa se sono state apportate modifiche strutturali a poppa del GW 2020 o se è rimasto effettivamente lo stesso del GW 2010? Qualcuno ha già montato Yamaha 425 su GW330 anno 2010? Grazie a chi può aiutarmi

Hmm, I'm out. All I get out of this is a 330 Express running a 425. Sorry.

I believe, and I could definitely be wrong on this, that he’s asking if he can run twin Yamaha F425’s on his 2010 GW 330 Express that currently has twin Yamaha F350’s on it? Which the maximum horsepower for that year and model is only 700 hp, so no that wouldn’t be a possibility.

Good morning everyone. I am looking at a 2010 white Grady 330 express and would like to power it with a pair of Yamaha 425 '. If the boat were from 2022 there would be no problems ... but this engine was not planned for 2010 (max torque 350). Does anyone know if structural changes have been made to the stern of the 2020 GW or if it has actually remained the same as the 2010 GW? Has anyone already mounted Yamaha 425 on GW330 year 2010? Thanks to those who can help me

La cosa migliore è chiamare il servizio clienti di Grady White

So basically what I said… :cool:

To the OP, I’m not sure if you can make any structural changes to the stern to accommodate more horsepower but would think a call or email to Grady White would probably answer that question rather quickly for you.

I'm guessing a call is out of the question. :)

Probably, although they might know someone who speaks English. I think the more likely scenario would be for the OP to use a translator service online and then just email GW.
