How fast can 120 hp boat engine go

At 4000RPM with ballistic 24 In calm weather the boat does not run in the desired way. The average marine diesel engine will run for more than three times that long and log an average 5000 hours under the same conditions.

How fast can 120 hp boat engine go. 120 hp force speed. Astro bass boat has a 120 force and i get about 52mph on calm water and full 25gal. Tank with all fishing gear.

I have a stainless 19 prop and motor runs at 5600rpm at wide open. With only 120 horsepower I reach speeds of 70 mph with one person and low to mid-50s with four people. Matthew Green TUNNEL MITE.

20 hp motor 165 lb driver 35 mph. Fuel Density in poundsgallon. Gasoline is about 61 lbsgallon.

Approximate Motor Weight in pounds. Just a guess to start. Adjust using real data after.

Secondary Propulsion Weight in pounds. This could be a kicker motor or an electric trolling. Shaft horsepower is to be the actual uncorrected engine horsepower less drive train losses.

Adjustments of -5 to -10 of corrected dyno figures are typical. Optimum Slip Percent For max top speed Heavy V bottom. Low drive height cabin side by side engines.

10 - 13. High Drives boxes notched transom good bottom. 8 - 9.

Speed limits are local not state wide. I believe there are no speed limits for boats for the reason most boats cant go all that fast. 2008 skeeter WX1880 yamaha 200 HPDI hits 565mph GPS with a 3 blade prop.

My 97 WX1850 with a carbed yamaha 175 pro-v would hit 60mph GPS with a 4 blade prop. They are also used on jon boats large canoes 9-12ft inflatables and small fiberglass boats ranging from 11-16ft. Boats in this class usually weight from 120-600lbs.

These engines are often transported and moved around fairly easy. You can expect to go about 15-25mph on light boats. We have had it out in Lake Simcoe North of Toronto on a pretty rough day 2-3ft waves and we were fine we had to back off the throttle a few times when larger waves came by but overall it is a pretty stable boat.

With 120 hp it will do about 35-40 mph easy. It is a nice and wide boat offers a lot of room on deck. Under perfect ideal conditions and only one person in the boat it can hit 31 mph 48 kmph 21 with lifting strakes and a 90hp engine and perfect conditions gets 36 mph 58 kilometers 18 Bass Buggy with 60hp engine can go up to 18mph 29 kilometers Suntracker 22 with a 70hp engine can get 21 mph with a light load 34 kilometers.

The Life Expectancy of the Marine Engine The average marine gasoline engine runs for 1500 hours before needing a major overhaul. The average marine diesel engine will run for more than three times that long and log an average 5000 hours under the same conditions. The number of hours that.

Due to the riders feet being immobilized falling off the board at greater speed is extremely dangerous and can easily lead to broken legs. No slower than 15mph. The average speed is around 22mph 35kmh and the extreme sport version aka.

Hauling goes up to 35-36mph 56-58kmh. Starting the Evinrude XP100 on my classic Crestliner boat. It would be a similar process for any EvinrudeJohnson engine of a similar era and the overall pr.

Calculating a boats fuel consumption proves important to boaters for number of reasons. With knowledge of a boats fuel economy-how much fuel the boat burns per mile or nautical mile of travel-boaters can estimate the range they can safely expect to run. Brian from Sea Foam shows how to help clean your boat engines injectorscarburetors and chambers by adding straight Sea Foam to the fuel filter.

How Much does a Boat Motor Weigh. Obviously motor weights have many variables including age size accessories and type. Here is a quick list of average weights for some popular models.

15 hp 122 lbs. 25 hp 155 lbs. 40 hp 220 lbs.

50 hp 237 lbs. 60 hp 250 lbs. 75 hp 350 lbs.

90 hp 350 lbs. It does the grunt skiing and tube pulling not to mention the old lady is going ro e screaming bloody murder if the boat is going 60 mph with her in it. I dont think in prop ratings.

Mine is an engine rated 90 HP. That would be what. 80 HP at the Prop.

So if I can build a reliable 120 HP at the prop I have gained prop 40 HP. The Sea-Doo RXP in particular is the fastest watercraft thats powered by a traditional-engine. It comes with a 255-horsepower engine that gets it from 0-55 mph in 29 seconds.

It also tops at over 70 mph. The brand is also known for producing jet skis designed for specific needs. If you need a jet ski for pulling Sea-Doo is the brand for you.

I have 135feet little boat. Motor is Evinrude 90 1987 50mph is my best top speed. At 4000RPM with ballistic 24 In calm weather the boat does not run in the desired way.

When is no waves boat run about 45mph but boat heeling strongly at left. If I trimm a motor heeling is lighten. But now boat riding nose goes up and down.

The amount of power that can be increased is directly proportional to the size of the engine. For example obtaining two extra horsepower or hp from a 120 hp engine may not be difficult but would be impossible from a 5 hp engine. I am trying to figure out how fast my Tracker should go and how if possible it can go faster with minor tweaks.

How fast does your tracker go. Include your setup config too please. 2008 Tracker Pro team 175 TXW max hp 75 hp 2008 Mercury 50 hp ELPTO with approx 16-17 hours on it.

Prop is whatever came standard on the engine. I would avoid anything that has a Force motor on it. I had a 1998 40HP motor on my boat.

Blew a cylinder in it in 2002. Before that I had to replace tilt and trim solenoids in several times where they went bad from the vibrations in that motor. I replaced it with a 2003 Merc and have not had any problems at all with it.

Many boaters know that throttling back can save fuel. Below are numbers to show the savings possible through careful handling. To determine an average fuel usage at gallons per hour gph divide horsepower by 10.

Therefore a boater with a four-stroke 250-hp marine outboard engine running at full throttle or about 6100 rpm is using 25 gph.
