Express 330
I have a 2007 33 express with twin Yamaha 250 and I feel she needs a little more of power and I am thinking to put a pair of Yamaha 350. Would u recommend me doing the change? Does my transom resist the weight or I need to make some reinforcements?

My buddy has a 2006 33 express and has twin 350 Suzuki’s dual probs and it makes that boat jump on plane and does 51mph. I seen him go from 250 Yamahas to 300 Suzuki’s to now 350 dual probs and it made that boat with the new 350’s.

Unsure whether you'd have to strengthen the transom to accommodate the 350's. Others will have to expound on that.

I love my 2018 Yamaha 350's. Mine are great, but I would do serious research on the older models as they had problems. Even with the newer ones like mine you have to replace the flywheels when the engine logs 80 hrs between 3500-4300 RPM's.

To me, that's not a big deal. I think they are a great match for the 330, the 250's were not enough. Be very careful and through if you consider Yamaha 350's, especially older models. To me, the performance and power of the V8's were worth the risk. You may feel differently.

Luck to 'ya.

Yes to above. The 350s appear to have fixed some of the issues. They are a beast of an engine.
