In addition doing this can also improve your gas mileage and make your boat ride smoother and more comfortably. Pmv or inertia mass x velocity.

The speed of the boat engine the material out of which the prop is made and the number of blades determines how much speed you can get out of the propeller.

How can i get more speed out of my boat. How To Make Your Boat Faster. The horsepower-to-weight ratio of your boat plays a huge role in speed and efficiency. You cant rebuild your hand-laid glass boat out of vacuum-bagged carbon fiber but if you carry less gear and fewer stores aboard your boat will be faster and more efficient.

Use these eight tips to get more speed from your boat. Changing props could help you gain an edge in performance. Courtesy Fountain Powerboats Iconic Marine Group Maybe it wont plane quickly enough the rough-water handling is unpredictable or the propeller ventilates in hard turns.

Help me get the most speed out of my boat If you want to go faster first thing is get the cavitation plate above the boat bottom. Is your prop cupped. If not it must be in order to run the motor higher than 17 or so on the transom.

There are three quick and easy modifications you can make to your boat which will allow an engine thats not quite hitting its peak to run a bit faster. Shedding weight from the boat changing the propeller and in the case of outboards jacking the engine up. The speed of a propeller depends on many factors.

The speed of the boat engine the material out of which the prop is made and the number of blades determines how much speed you can get out of the propeller. Boats can be made to go faster or slower depending on the usage of the boat by changing or replacing the prop. Pmv or inertia mass x velocity.

To get more speed out of your boat you need to increase the jets output velocity. This can be done by increasing rpm and maintaining the same nozzle orifice less efficent or maintain rpm and orifice but increase the size of the impellor. Increasing the pitch by an inch or two decreases the RPM accordingly and puts you back in the RPM range sweet spot.

If the motors RPM is below the manufacturers range the boat is over-propped and decreasing the propeller pitch will increase the RPM to where it should be. Before the advent of electronic engines this was a matter of trial and error. Run boat note rpm and speed change to props with more pitch or cup run boat again and if you get more speed repeat until speed drops off.

Changing propellers may make a big difference in boat performance learn more in Boat Propellers. Repairs and Replacements but propping is a complicated science and a high-performance prop is a significant investment600 to 800 and moreso you want to get it right which means seeking some expert advice from a boat dealer or propeller shop. The first is to get any excess weight out of the boat as weight kills performance especially for a small engine like a 25.

Secondly get a higher horsepower engine on the boat. If Land and Sea made a power shift prop for this application you might gain some of your desired performance. But youll notice youll get a lot more speed top-end out of your boat.

The boat performs better. You get better fuel economy. Any time you get better speed youre going to get better fuel economy.

But just remember when youre rigging your boat up or setting your tackle up try to put everything heavy in the back. Basically my boat is rigged up. A dirty hull will definitely slow your boat downwhen I was wet slipping my old boat before I got an air dock my top speed would drop from 49 to 35.

Clean the hullright back to 49. I would also check your intake grate to make sure all your sealant is in placemissing sealant will cause turbulance in the intake and drop your speed. This is common.

Something between 12-15 is the ratio that will work the best for your setup with a 13 or 14 prop. A lower gear and prop logic sometimes works better on a planing hull for top speed but too much keel in the way blocking water flow for a high shaft speed. If your boat could originally go 35 mph without the Murphy and you have gotten rid of a lot of your drag then you can go faster or reduce throttle for economy.

But at speeds above 35 mph your Murphy becomes more and more of a drag till you reach a maxim speed. Now we take the original boat and put a half size Murphy on it 6 square inches. The more the props pitch reduces the lower the speed in which the boat stays on plane gets a fact that is particularly preferable when we travel in rough seas and the boat should be held on plane at the possible lower speed.

The more the props pitch reduces the better the behavior of the boat gets concerning the grip the acceleration. With a prop designed for high loadlow speed maybe an 11 pitch is OK because they will drive slippage to a relatively low number. But in reality your boat is too small and light to require such heroics.

Also we get about the same speed as you with our 2080 RL and 90 HP 2004 F90 4-cycle. Installing a jack plate on your boat for the outboard can allow your boat to go faster. A jack plate will lift your engine up in the water and bring your propeller closer to the surface of the water.

As a greater part of your engine is now out of the water. That high performance outboard hanging on the back of my bass boat isnt the same two-stroke engine my grandfather used to putt around his favorite fishin hole. My Nitro z9 powered by a.

The motor was set by the dealer at 25 above the keel line. The prop on the motor is a 17 sst 3 blade powertechThe hull weighs about 560lbs. I took the boat out the 1st day I got it and was only able to turn about 5600 rpms at 35-36 mph.

I was able to get the boat up to 39 mph and 5700 - 5800 rpms but only while porpoising really bad. One trick that can help you get a little more performance out of your pontoon is to change the angle of your motor. This is also called as trimming the engine and can reduce the amount of resistance underneath your pontoon.

In addition doing this can also improve your gas mileage and make your boat ride smoother and more comfortably. Sail downwind for a slight speed increase of your boat expect to feel it only if the wind is strong enough. Nevertheless it should give you a small 1 to 3 mph boost which will make your experience smoother and more enjoyable.

Load the boat properly. Put all the heavy gear in the back of the boat. That includes soft plastic lures tools and anchors.

You may lose a little in the holeshot but the boat will use less energy for forward propulsion which equates to speed and better fuel economy he adds. Youll be shedding weight and gaining horsepower. Likely you have too much weight at back of boat.

You have a 30hp weighing what ever a 30hp weighs but only putting out roughly 20hp. Do what I have done and get as much weight out of the ass end of the boat. Gas cans batteries gear should be moved as far to the front of boat as possible.
