Prop advice

[565edge]

Looking to buy some props. I have a 1992 20.4 stoker with 4" set back and a 1993 merc 2.5 260 offshore,brucato box,boyseen reeds,1" reed spacer, Has sportmaster lower. Center of Prop is even with bottom. I see people talk about big shaft and small shaft. Is mine a big shaft?It has a mercury lightning et. Maybe a copy.It has bronson hill on the blade and it says merc on the prop. Was told its a lightning et. I am a big guy at 375 lbs. Want to buy a trophy 25 pitch just not dure what shaft I have?Also want to try a chopper? Do I need the vent holes? Any help would be appreciated...Thanks

You have the small shaft. As I recall, they went to the larger bravo sized shaft around 1999 or 2000.
My advice is to discuss prop selection and setup with Al Stoker. He has done a ton of experimenting and study of that hull and can save you years of work.
I'd be shocked if a Trophy was a particularly good prop for that hull but if you have a lot of weight in the front, it might be. Al will know. :cool:
