Will a 1000 pound 16ft 94 larson fiberglass boat have plenty of power with a 93 90hp evinrude?
Yes...with correct mounting, prop pitch, and a well operating engine, you can drag waterskiiers around behind a 17' boat with 90 hp.
Why does a 2000 115 evinrude slip over 5000 RPM Its on a pontoon. Pulling tubers upto 5000 is ok. If you get to 5000 RPM it acts like it is slipping with new prop. We put the old one and its the same.?
Your prop size is too small, with all the drag of the pontoon and a tuber, the prop will begin to cavitate in the water at a certain speed. Unfortunately for you, that speed is at 5000 rpm. Luckily this is pretty easy to replace. Your local boat store will back me up on this one if you go and ask them... Before the new prop, the old one would pull me skiing and tubing. We upgraded and a month later the above problem started. We changed back to the original and wha la it is still happening.
Evinrude 25 horsepower outboard prop slips while under a load. Or could it be cavitation?
Sometimes the center of the prop breaks loose and slips or the splines get stripped. Also check to make sure you have the correct pitch prop for that motor and it is fastened securely.
Does Evinrude 9.5 HP have shear pin prop?
Yes, it does.
What is the speed of a 260hp boat engine?
there are way too ,any variables to answer your question. It depends on the boat, the boat size, weight, kind of prop and pitch etc.
What is the correct prop pitch for a 7 and a half hsp Mercury 5699828 It has a 7 pitch 3 blade on it but seems to spin out?
Usually pitch is set according to horsepower AND boat size. You could try a taller prop, say a 10 pitch, but you are going to lose RPMs because to engine is cutting through more water. It's a give and take situation. If you can get the boat to a good prop shop near the water, most will let you try different props until you find the one you like.
How do I determine the right propeller for my 26' pontoon boat with a 1998 mercury outboard 90 hp motor?
The propeller size is determined by the engines wide open throttle RPM Let take an example of an18' boat with a 125 hp engine with a rpm range of 4500-5500. In most cases you purchase a boat with some sort of propeller on it. Let's say this motor has a 21 pitch prop on it and at wide open throttle under a normal boat load, the engine turns 4900 rpms. Well it's in the range so it's the correct prop, right? Well yes and no. For the health and longevity of the engine it's okay, but for overall performance, you want to run a propeller near the top of the range. An 1" of pitch in a prop can change the RPM 200-400. If you need more RPM decrease the pitch and vice versa for less. Remember this is a trial and error and not an exact science. Factors like loading the boat, fuel and water all have to be considered.
What is the average speed of a motor boat?
There are to many variables that go into that question . Boat weight , motor size , prop pitch and diameter , form of the boats hull ( flat or a v hull ).
How much thrust does a 15 hp outboard motor produce?
On average 1 HP Equals 25-30 lbs of thrust Depending on Prop Pitch. So a 15 HP would give you 450 lbs of thrust. I had a 18HP Evinrude Fastwin on a 14 ft Aluminum Jon Boat that would get water ski's or Hydro Slider on plane.
What is the fastest 15 hp outboard?
I have a 15hp Nissan 4-stroke on a 14x32 Jon Boat and have a 13" pitch Powertech Prop and I get a max speed of 34.5mph.
What is the max speed for 1999 125 HP Mercury outboard motor?
The maximum speed of the 125 mercury is dependent on the boat it is on. It can only push some boats 2mph, while other boats that are light and have a small wetted surface can run 60. To find the theoretical maximum, you should find the maximum pitch prop offered for that engine. The maximum pitch prop I can find for that engine is a 24p. The gear ratio for the lower unit is 2.07:1 . If you can turn the 24p prop at the maximum recommended rpm 5250, the fastest the boat could possibly run is 57.1 mph. The propeller is not 100% efficient, so you should factor in the slip of the propeller. With the inefficiency (slip) factored in, the boat would be more likely to run 55mph. If you can find a higher pitch prop for that engine, you can get it to run faster speeds. A 27p prop would run about 60mph.
What is the disturbed water left behind a boat called?
prop wash
