I would not expect much more of a difference. Some with the F200 are reporting as fast as 43 mph, and it appears to be a great motor. However, what it lacks in power, it makes up for in comfort and style. The Horsepower Calculator will calculate the horsepower of any vehicle instantly if you provide the total weight in pounds of the vehicle (and its occupants) and the MPH (miles per hour) that the vehicle is traveling the instant the vehicle crosses the finish line for the quarter mile (called the "trap speed"). If you can lower that amount of horsepower you need by increasing hull efficiency (trim, polish, design, and most importantly, weight) you can reduce the amount of fuel you need to cruise at the same speed. Thrust had used twin Rolls-Royce Spey jet engines taken from the F-4 Phantom fighter, generating 9,979 kg of thrust (91. Its unique hull design makes it capable of thrilling 360-degree turns and spinning on a dime. 5 MPH, whereas at 2500 it was only 12 MPH, once again proving the inefficiency of stern drives. A simple equation for kinetic energy is 1/2 x mass x velocity squared. Logged I didn't do it ok, it was me. I recommend Bravo 3 XR props if buying with a MerCruiser, and 425 hp if you like speed over 50 mph. Fun Cruisers : Model Pub Engine HP Outdrive Time to Plane Top Speed WOT RPM Moderate Speed RPM MPG @ 25 MPH MPG @ 45 MPH Prop; 2660 Z-Trak DC : BL : V 8. 4 - Porta-Bote needs only a small 4HP- 6HP outboard to go up to 15 mph with one person. The exact same boat rigged with the F150 turns just 3500 rpm to get up to 27 mph, while it cruises at 37 mph at 4500 rpm, and gets 4. Extended swim deck. 1985 Checkmate boat with 25 hp Johnson outboard. In such instances, the slip represents the total efficiencies lost in the design and set up of the boat. A 255 HP Jet Ski will do a LOT more than 60 MPH!!! My nephew has one with 150 HP and when I rode it last summer I got it to 70MPH and there was a lot left. I took a picture while I just made a final payment, out to first try how the boat run, it was still within break in period (of course it was still within 0. Note: For flat bottom hard chine boats, with a factor of 52 or less reduce HP one capacity increment. These motors typically use a manual start system , with throttle and gearshift controls mounted on the body of the motor, and a tiller for steering. 9 hp 8 hp 6 hp 4 hp 2. They are compact, easily stored and trailers as any small outboard. In a properly setup boat an old rule of thumb was 600 net hp would produce approximately 6000 RPM on a B impeller and 100 MPH. AB Yachts combines three 1,900 hp MAN diesel engines and three Marine Jet Power water thrusters to propel the AB 100 yacht up to 54 mph. I have a 2000 model year and after purchasing a replacement parts manual from Mercury, which covered both the 75 and 90, I concluded that the only difference was the high speed jets and the timing advance. Mounted to a 17-foot Action Craft bay skiff (910 pounds), the 90 hit a top speed of 40. 9 diesel 190 hp (142 kW) Suspension Torsion bar Operational range 450 km Speed 50. Seven Marine is committed to providing world-class outboard power with its 557 and 627 outboard engines. I fished with a guy who had a 150 Optimax on an 18 ft Lund. Lets say I have a 18ft deep v weighing around 2800 lbs, and I want top speed to be 35mph from an outboard motor, how much hp will it take?. A third set of tests compared a 135-hp, two-cycle DFI outboard against a 130-hp, four-cycle outboard on identical 20' boats. Reference resources for Evinrude Boats 1964 - 1970. This motor has only been used in freshwater for very low hours and it runs perfectly. At wide-open throttle, the F115 propels the Dominator to 39 mph and gets 3. 15078 mph in kn. The calculation becomes interesting when calculating the power produced by a windmill at a given wind speed, which is a function of the sail area of the blades. HONDA OUTBOARD APPLICATION CHARTS 7. As a follow up, this week's #TrainingThursday will cover How To Calculate Fuel Consumption. If you want to stay below the $20,000 mark, you'll need to stick with the stock Mercury 90 ELPT FourStroke outboard, which has an estimated top speed of 44 mph. If you want to run fast - run a flat bottom boat - like a hydro or some of todays bass boats - which have essentially a flat planing pad on the back of the boat - on which they run. If we take a 20 outboard propped for 30 kn speed, we have only 5 lbs/HP. (horsepower) hp: Empty Hull Weight & Engine (lbs): lbs: Number of Passengers @ 170 lbs each: crew: Fuel and Gear (lbs): lbs: Altitude above sea level (ft): (power loss = 4% per 1000 ft ASL) ft: Hull Efficiency factor: enter 165 to 225: OMC Boats use 170 - 175 or 180 if using SST prop: Calculated Top Speed: mph: Displacement (Gross Weight): lbs: Prop-shaft Horsepower: hp. There is a fine line between overpowering and under powering your watercraft. 8 miles per hour is still nothing to poke fun at. Hated this motor.
