I bought a 420 renegade a few weeks back and went for the 50hp it gets up on the plane easily compared to the 40

Depending what performance gains you're after I guess.

Prop selection may even help depending what gains you desire.

Sorry about the time getting back to you my intention is now to just have  an alloy cover above the prop I cannot think of  the correct name of this item but it controls cavitation and brings the boat up to the plane quicker. Top end speed is not all that  important as l will  be in a continuous sea swell in Broke Bay 

I was told at the weekend that it's cheaper to replace a prop than a new drive sharf. What do you think..?

  Thanks for your input

Its called a hydrofoil & the jury is still out imo on there effectiveness, sometimes causing more stabilization problems than benefits!

Have a read through some old threads & make up your own mind-

 

 

 

 

 

Better weight distribution helped me out but more power would be handy
