Re: 4 blade vs 3 ?????
Can't tell. We have no idea what boat, what current performance is (speed and RPM), and what you are trying to accomplish. Boats don't have transmissions so the prop needs to do that job. If you want speed -- think three blade. If you want hole shot and smoothness, think four blade. Changing props is not just a "I want a four blade" or "I want a stainless" decision. Those changes are made for a reason. Stainless for durability and efficiency. Aluminum is less costly and less apt to ruin a lower unit if you strike a rock, stump, etc. We need some wide open throttle and speed measurements to help you. Acceptable hole shot is whatever the seat of your pants tells you. Top speed is whatever the speedometer registers. Speed and hole shot are a compromise when it comes to prop selection so you need to determine what characteristics you want when making those decisionis.
