How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

Loose fuel line connections, pinched or blocked fuel lines. It would be best to inspect all fuel lines for any bad connections, damage to the line, and leakage issues. Replacing a damaged fuel line is typically the best course, as repairing a damaged line naturally leads to further problems within a short period.
A cracked, clogged, or otherwise worn fuel pump is often the reason a Mercury outboard cranks but won`t start. Consult a repair manual for your engine model and year to determine the proper replacement part.
The outboard engine is too old, parts are likely scarce, and the technology is dated. If it`s an `80s engine with some or all the features previously mentioned, and a new engine is out of the question, rebuilding can be a good option that will add years to your old outboard`s life.
A spun prop is one of the most common reasons your powerboat may struggle to achieve appropriate speed at full throttle. This happens when the bond between your boat propeller and prop shaft is damaged. As a result of this damage, the rubber inserts start spinning independently.
The engine can be running or not when flushing, and flushing should be for at least three minutes. Mercury notes that this procedure should be used when flushing the engine after use in salty or dirty water, and also as a part of preparing the outboard for storage.
A full flushing of the motors must be done after every use, and it`s recommended every six weeks if it`s been sitting in storage. It`s important to run the motors long enough for the thermostat to open, allowing the fresh water to flush the salt from the entire powerhead.
Higher budget: While engine replacement is costly, it is often much cheaper than a new vehicle. If you have a larger budget to spend on your vehicle, you might consider opting for a new car.
Repowering your engine with a rebuild costs as less as 10% to 20% the cost of a new vehicle. Moreover, you can also save significantly on annual insurance costs on an old vehicle than a new one.
Every boat owner is different and how far you decide to push your marine engine is in your hands. However, running your boat at Wide-Open Throttle is not bad for your engine and can even help clear out carbon build up.
Clogged Fuel Filter

Another common reason why your engine is bogging down when you apply throttle is a clogged fuel filter. The fuel filter`s primary purpose is to strain out any debris and dirt that may reach the engine, but the fuel filter itself can become blocked if there is enough debris.

It could be dirty fuel and a plugged filter, a problem in the fuel pickup tube in the tank, water in the fuel that was getting past the Racor, an air leak or even a kinked or collapsed fuel hose.
Mercury motors claim to last thousands of miles, but like all other motors, this depends on the care, maintenance, and use. With the proper care and cleaning, Mercury outboard motors could offer you over 2,000 or even 3,000 hours of use.
The main reason for your outboard engine not working will be the fuel system, often because fuel has been left in the engine over winter. The fuel goes through a chemical reaction producing ethanol, which will prevent the engine from running. There may also be dirt blocking the filter, lines or carburettor.
Every Mercury outboard has a serial number label located on the transom bracket area of the engine. The latest serial number labels display a 2-digit number in a box at the lower right portion of the label. These digits coincide with the last two digits of the year in which the outboard was manufactured.
With proper care and maintenance, many 4-stroke outboard engines can last over 3,000 hours before requiring significant repairs or replacement.
An engine flush is an aftermarket chemical additive designed to clean accumulated deposits, sludge and other gunk from your engine. You pour it into your engine`s oil-filler port and idle the engine for about 10-15 minutes.
Failure to follow the “break in procedure” for an outboard motor can result in mechanical failures, reduced life of the outboard and even a voided warranty!
In order to protect your investment and keep your boat looking clean, it is important to wash it on a regular basis. If you do not keep your boat stored in the water, then the best schedule to keep for washing it is after every single use.
The presence of oil and its distribution is absolutely crucial to an engines continued operation. Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing – and in most cases, it`s a lot quicker than that.
Most mechanics and engineers suggest the best cruising speeds are achieved at 3400 and 3800 rpm respectively.
Vinegar will dissolve some of the corrosion, but it will also leave a surface that is primed for new corrosion to rapidly begin. After use, you would want to neutralize the vinegar with something like baking soda to stop it`s action and then coat the surface with something to slow down the new corrosion.
Used engines can be more reliable than a new one as the used or recycled engine has been tried and tested on the road and not just in a factory, used engines have already been `run in`. Choosing to purchase a used engine is better for the environment as you are recycling a perfectly good engine.
But most experts advise against such a job, unless the engine is relatively new and you know that it needs only a few specific parts replaced. If you have a generally worn-out engine or an engine that has suffered major damage from loss of oil, it almost always makes more sense to buy a fully remanufactured engine.
How much does an engine rebuild cost? Depending on the type of engine, it can cost between $1,500 and $2,000 to repair one. The price of a four-cylinder engine ranges from $500 to $2,000. A V-6 engine can cost up to $2,000, while a V-8 or V-10 engine can cost more than $4,500.

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.
ANSWER : Every sympton you are describing here can be attributed to fuel starvation due to blocked jets and or water in carbs, when your engine dies does it die with dry plugs, or wet oily ones?

I have a 2001 Yamaha XL700Z Waverunner. The compression on both cylinders is about 120, it starts and runs fine – dry. Won’t quite idle, but I can start it and rev it up fine (for a short period, of course). However, as soon as it gets in the water, it will barely run – it will start and sputter and you cannot get it to run more than a few seconds or rev up. Take it back out, let it dry, starts & revs fine. It is not getting any water in the casing that I can tell, its almost as if water is getting something wet through the cooling system that I cannot see?
ANSWER : Try cleaning the carbs and the fuel lines, filter

I have a volvo penta md7a marine diesel engine fitted in my sailing boat. Recently, I changed the bottom sea **** which was almost blocked. Apparently the new sea **** is working well as it should. But this week with no apparent reason and without use of engine, I noticed that the cooling system water cup (the recipient which connects with the sea **** hose and the water pump hose) is empty and it Im not able to keep it full like it was before.The water vanishes every time I tried to fill it up in order to keep the water running throught the system. However the waterpump seems to be working. But almost no water is coming out of the exhaustor, of course, just a few drops once in a while. What might be going on ?? Thanks.
ANSWER : I don’t have a picture of the installation, but I can imagine a water filter above the water line with an improperly fitted cover and an air leak that lets the seawater drain out – losing the prime. Old Swampy in New Hampshire

Mar 12, 2010 – Could it be the check valve? I took it off and the flap appears to be working correctly. This well has been here a long time. Never given me any problems. I do have galvenized couplers on the discharge and intake sides. Old. Could these be leaking even though they show no sign of water? The discharge is able to hold 30 pounds easily overnight. I do not hear any vacuum in the intake when I take it off. Could the pipe to the well have a leak? I know I would have to insert a sleeve bnut I do not want to go through the hassle if I do not have to. I had put on a brand new pump from the hardware store that did the same thing so I think that would elliminate the pump as being the problem.
Mar 12, 2010 – I have a 3/4hp flotec convertible jet pump. It is able to hold 30lbs pressure on the discharge side as the primie easily for 24 hours. It is not able to pull water from the well whcih has been here for years. i disconnected it for the winter and rehooked it up. The galvanized couplers on the discharge and pump side are old but do not appear to be leakeing as I taped them well. The check valve seems to be functioning well as I took it off and the flap works correctly. The well is not pulling watrer. there does not appear to be a vacuum on the check vale when I losen it. could the check valve be bad? I am aware I might have to resleeve the well, but do not want to hassle with this if I do not have to. I want to eliminate everything else first. i put another brand new pump on it to see if it was that. That partiuclar pump which was the same thng did not work either.

ANSWER : Your well has gone dry it seems. It has happened to my before. At first the new pump I purchased that did not pump I took back for exchange and still no water. I finally gave in and called the well experts and I was told the well was dried up
