what size prop should I use for my 255 conquest with a 250 efi merc. I currently have a 15 inch pitch and can only fet 5000 rpm and getting on plane is a slow process

Assuming your current prop is a 3bld. stainless, it sounds as if a 4balde 13" pitch would give you a much better hole shot and get your rpm's up closer to the 5400-5500 range.

The minimum hp for that model is 225hp and that is a heavy boat.

I would strongly recommend looking at Mercury Revolution 4.

When moving to 4 bladed prop, the pitch may not translate.
