not crank, absolutely nothing when you pushed the engine mounted start button.
** I disconnected the positive lead from the battery to the engine and started troubleshooting with an ohm meter.
** In the course of troubleshooting I noted that the 20amp fuse in the small black holder mounted below and to the rear of the solenoid had blown.
**I replaced it with the on engine mounted spare.
**When I started to reinstall the positive battery cable I noticed that there was obviously a current draw as there was some slight arching when the power cable contacted the positive battery terminal.
**Since I have switched this motors controls from tiller steer to a wheel steer i have left the start switch on the engine but moved the kill switch and an on/off switch to the small center console.
**Both the on/off switch and the kill switch were in the engine off position.
**Other info: Obviously something is drawing current so i have left the battery unhooked. BTW the engine now does start and run when the starter button is pushed. I had noticed the day before that when i was test running the engine the evening prior to going out that my electronic tach stopped working. After noting the small sparks i tried disconnecting a few things and noticed the sparks stopped when the red wire to the ignition box was disconnected.
***Any clues as to what is wrong here??

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. :
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.
If it`s not engaging or turning over, you may have a faulty electrical system. For electric-starting models, you`ll want to check the main fuse to confirm it`s not blown. Start by unscrewing and removing the electrical cover. Next, use a pair of pliers to remove the fuse holder.
If you have checked the battery switch and charged the batteries, but your boat engine still won`t start, check the battery cables. Make sure the connections that run between the engine and the battery are not loose or corroded. Reconnect or replace any battery cables that have become disconnected or damaged.
25 – 15 hp 25 hp
Our 432-cc 25-hp portable outboard features a streamlined, portable design and class-leading power-to-weight.
Old spark plugs are another culprit which might make a bike hard to start. If the plug is old and worn the spark will be weaker, making it more difficult to ignite the mixture. Keeping fresh plugs in the engine can greatly improve the bikes starting tendencies.
If the engine cranks slowly or doesn`t crank at all, it`s possible your battery may be dead or low. Use a voltmeter to check the condition of your battery. If the voltmeter reads below 12 volts, your battery most likely is the problem and may need to be jumped or replaced.
No. A battery is not required to run the rope start models. However, if you have electrical accessories you want to operate and would like to take advantage of the charging system, the capability is already there.
Maximum output: 25HP (18.4 KW) Maximum operation range: 5000-6000 rpm. Fuel Consumption at W.O.T: 8.8 L/Hr.
The all-new F25 Portable four stroke features a Single Overhead Camshaft, 2-cylinder powerhead, for a compact design that weighs in at only 126 pounds.
Spark plug fires and ignites the compressed air/fuel mixture just before the end of the compression (i.e., previous) stroke. This ignition/combustion forces the piston down the cylinder bore and rotates the crankshaft, propelling the vehicle forward.
Following this achievement, in 1998, Yamaha developed the lightweight, fuel efficient F100, which utilized dual overhead cam technology, and the F115, which was equipped with an electronic fuel injection system.
Always warm up the motor thoroughly at idle before running at higher engine speeds. For the next eight hours you can run the motor in standard fashion but never for longer than five minutes at wide-open throttle.
While 4-stroke engines perform well and generally last longer than 2-stroke engines, 2-stroke engines are lighter and faster than 4-stroke engines.
As you`ve read, the 2-stroke bikes have smaller engines, are lighter, have less traction, but more initial power. 4-stroke bikes are heavier, have more stability and traction on the track, but have the higher horsepower for overall power. This means that both are fast.
Pull the starter cord or turn the key to turn on the motor
If you have a starter cord, pull slowly until you feel some resistance, then yank it quickly and forcefully. It may take several pulls to get the motor running. If you have an electric start motor with a key, just turn it forward in the ignition like a car.
A four-stroke engine is an internal combustion engine that utilises four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. A complete operation in a four-stroke engine requires two revolutions (7200) of the crankshaft.
A dead battery is the most common reason why engines fail to start up. A common reason for batteries to fail is drain. Your car`s battery typically expends a small portion of its storage to start your car up, and then recharges from your alternator as you move.
If you do have a blown engine, whether or not it can be fixed depends upon the extensiveness of the damage. If the damage is minimal, and a few parts can be replaced, the problem can be fixed. However, if the damage is great and impossible to repair, you may need a complete engine replacement.
Open the throttle quickly. You should see the accelerator pump system discharge a squirt of fuel into each primary barrel. The flow should continue for a few seconds after the throttle valve reaches the wide-open throttle position. If not, the accelerator pump system is defective.
A weak accelerator pump, worn throttle shafts, or dirt inside the carburetor are a few of the problems that might be causing the poor air/fuel mixture. Another recognizable sign of carburetor trouble is rough idling .
Putting a car battery in a boat will cause it to degrade much more quickly. You could possibly damage it and cause dangerous chemicals to leak from the cell. Instead, you should get a marine battery designed for the intensities of the open water.
100 to 1 Fuel Oil Ratio.
25:1 – Mix 200ml of oil per 5ltrs of fuel
This mixture is very rich and is usually recommended for running in brand new two stroke outboards and when running in rebuilt or reconditioned engines.
Generally speaking, you can expect a 25hp outboard to reach speeds of up to 25 knots, which is around 28. 7 miles per hour (mph). Smaller boats typically reach a maximum speed of around 15-18 knots, or 17.
