Black Max 150 Prop reccomendations?

[devonboy]

Hi,

I'm running a black max 150 v6 on the back of a bayliner capri bowrider 19ft

the antivent plate sits about an inch above the keel.

the prop on there at the moment is old and worn, looking at a new one and leaning towards fuel economy rather than top end speed
does anyone have a similar set up or advice on what prop (pitch and size) to look at?

Thanks

Sam
