[RESOLVED!] What Prop Makes A Boat Go Faster?

When a boat has a hook in the running surface, that means the aft section of the bottom angles down 😊 It acts like a giant trim tab, forcing down the bow, hampering lift and scrubbing speed 😎 The only way to combat hook is with excessive drive trim, and then you’re losing performance because the propeller thrust is angled more up than horizontal 😎 The best way to check your boat’s bottom for a hook is with a straight edge at the transom. A fiberglass repair shop will remove the hook and allow the boat to ride along its lines. This increases top speed and improves overall performance. [1]
Videos and Photos: Document the ProgressWhat once was a pain (a friend with a ­camcorder) is now easy-peasy. Your buddy can use his phone to record your boat’s speed, so that you can evaluate its performance. It’s a good way to showcase setup specialists and prop shops. Check to ensure that spray is exiting at the transom. If it does not, you will have a better efficiency. If there’s a rooster tail, it should be long and low — behind the boat 20 to 40 feet and no higher than the top of the outboard cowl — not high like a jet boat’s nozzle spray. The boat’s bow should be riding (“carrying”) at an angle of approximately 3 to 5 degrees positive incline, maximum. These visual clues are indicative that the motor-and-boat setup isn’t right. Pros can help you see how to get more performance. [2]

The specialists at boatingmag.comThe trick to choosing a propeller for your boat is to ensure that it delivers speed and acceleration. You can get assistance from a qualified marina or dealer, but it is important to know the following information. The following are important facts to consider: type of engine and its horsepower rating, the boat’s weight and hull style, and the type of propeller you are running now: number of blades, diameter and pitch. If you don’t know, diameter and pitch usually are stamped somewhere on the prop. Also know the engine’s rpm at wide-open throttle when your boat is running with a typical load and trimmed for best speed. Rayla Doran, Poza Rica de Hidalgo (Mexico) last updated 53 days ago [3]
