i've never seemed to have a problem with what comes on the motor

Motors above 25hp or so don't come with a prop from the manufacturer... you've had a good dealer / rigger that has put the right prop on your motor for your rig. Unfortunately not all dealers are that good.

Pitch-the theoretical distance the prop will move in 1 complete revolution

Propeller Rake - Propeller blades can be tilted fore and aft on the hub in relation to the boat. Rake affects the trim of a vessel as it changes the flow patterns of water moving through the prop. Raking a prop aft will improve top speeds of boats at WOT by trimming the bow up and reducing the hull area in the water. Negative or forward rake trims the bow down, improving performance of heavier boats at slower speeds

Propeller Cupping - Placing a cup in trailing edge of a propeller offers a few performance benefits. A cupped prop will bite into the water better offering less ventilation and a better "hole shot" out of the water to reach planning speeds. A cupped propeller trimmed near the surface of the water is more efficient and can improve speeds at WOT. Switching to a cupped prop of the same diameter and pitch will potentially cause a reduction of 200 RPM

The right prop compared to the wrong prop will make all the difference in the world in how your boat runs and handles, and marine man is correct in that it is the dealer or the boat manufacturer who sets your rig up with the right prop when the boat is new. It's not a bad idea to do some prop testing to see if a different prop will improve your boat for the way you like it --- in my opinion it can really make a difference once you get to 115 or bigger hp motors. A phone call to the boat manufacturer should get you in touch with someone who can give you an opinion on your current boat, motor and prop setup and give you a recommendation if there's something else you should try.

Also, if you don't think your bow is riding high enough, try shifting some weight to the back to see if it makes a difference. One easy trick to try to test weight distribution is filling your back livewell if you have one in your boat.

Another possibility --- a pretty rare one --- is a problem with the hull --- ie. a hook in the hull possibly caused by poor placement of the rollers on a roller trailer. It's not very often that you hear of this problem but it is something to consider if none of the easier remedies like prop selection and weight distribution are making a difference. Alumacraft leaves a small part of the hull extending past the transom which they can adjust to tweak the ride in each specific boat. If you're concerned about your hull or your trailer, the best advice is to go to the manufacturer (if you're close enough) or to a quality dealer and have them look at it.

Hope this helps.
