There is no simple answer to this. It depends on the weight and hydrodynamics of the hull and the horsepower and rpm of the engine. It also depends on how you want the boat to perform. For a ski-boat, you want a lot of power "out of the hole", for a speed-boat you might want top end performance. As a general rule, boat manufacturers pick a prop that puts the same power into the water that the engine is capable of producing at wide open throttle. Check with the boat manufacturer or dealer for recommendations. Other than that, the only way is to experiment with different props.

Just bought a 16 ft fletcher bravo 115hp evinrude e-tec with viper stainless steel prop 45mph flat out was a bit disapointed hoped 50 plus mph can i get it to go faster. can i fit 150hp on this boat.?
Hi there! I also have a fletcher 16ft arrowsport bravo, you should find that it will have a plate on the back of the boat that states 90hp is the max outboard size (or two holes where the previous owner drilled it out to sell it! ). 150 would be way to high for this boat! The best bet is to play around with prop sizes etc. Some props are good for acceleration and others for top speed. Find out the ideal rev. range on your engine at wide open throttle and test to see what it is at top speed. If the revs are below the recommended, then you need a new prop to give better top end. 45 knots is pretty good!! I wouldn't expect more from this boat. Is that on gps or internal speedo? The dash speedo will be out by about 5-20percent at a guess so you need to try with gps. ps: i think i saw that boat on ebay!
What size motor do you need for your 16 ft fiberglass speed boat?
Look at the manufacturers plate on the boat for max HP and or weight. If there is none either call them or consult a marine engineer or body and get a rating tag fitted. My two previous motors on my 16 footer have been 90hp and 115hp.

Why should a boat made of metal float?
The size of the boat is equal to the water displaced by the boat. This means, if the boat is bigger then its weight, the boat will float. If the boat is smaller than its weight, it sinks. This is why metal ships are so big.
