The motor runs fine out of the water, but fails under load

The motor runs fine out of the water, but when you put a load on it , the motor dies out in minutes. I can hear a squeeling sound coming from the foot pedal. If after it dies out and quits moving the prop, I press on the pedal to accelerate it pops the cover on the battery.

SOURCE: Prop spins slow on any speed on the foot pedal

There is a good chance that the control board is bad. This is a common problem with these units. I have replaced my control board twice. When the control board goes out, some function of the unit will not work correctly while other functions work fine. The first time mine went out, the prop motor would not work. The last time the board went out, the unit would only steer right.

I have a Troy Bilt trimmer model TB675EC...4 cycle engine. Problem that has arisen is that it dies at high speed and under load. Starts up and runs at idle well.

Fuel starved, carb should have an idle adjustment which sounds like it is fine. Look for the second adjustment

Not draining the tub


To my knowledge, most problems such as one you have can be caused by three (3) possibilities:
1. electronic - the activating circuitry that engages the drain valve is faulty;
2. electrical - the drain valve is not opening evening if electronically activated; and
3. mechanical - the drain valve is stuck or the most likely, the drain passageway is clogged.

The last would be your best option and possibly the easiest to correct.

To recap, you hear a clicking sound means that the drain valve opens, you hear the motor, means the drain motor is running, but no water drains out, that only leaves a clogged system.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

My 1988 evinrude 70hp outboard will run out of water perfectly. When in water...the engine just turns over and over but wont run.

Ignition or carb issue. Basically it runs fine under no load (out of water) but doesn't under load. Just had the same problem with a merc150. Diagnosis revealed a failing coil pack and a dirty carb on the same cylinder.

Honda rotor tiller dies under load but runs fine other wise

Its running lean. There might be a small amount of water in the bottom of the bowl that gets sucked up when the motor is under load and requires more fuel.
There is a drain plug on the side of the bowl. Use a 10mm wrech and remove the plug. Catch the fuel and inspect for water. If water is found drain system and refill with fresh fuel. If no water is found then a carb rebuild is needed

I have a 20 hp mecury jet outboard motor that runs fine out of water but as soon as you put it in the water it'll run for a few seconds and then die and will not run again. It will soind like it&#

the rubber components of the fuel system from the tank, primer bulb hoses , fuel pump all deteriorate internally and the small rubber failings get to the carby and block all of the run circuits
experience says take it to a mercury service center and have the carby/s professionally overhauled as doing ti at home generally misses the important bits
never use e-mix fuels as the ethanol attracts water and the combination rots metal bits and hoses

Washer fills, then just hums for about two minuts and shuts down

The hum sound is coming from the motor that is probably bad and needs replacement. Hope you understand...the washer fills with water which indicates that the control and the water inlet valve are both fine however, as after this you hear a hum sound it means that the motor is bad. Please get back to me if you have any other questions.

Car dies after driving through some water (it has been a week)

I believe you have a motor from GM where your distributer is on the bottom and therefore your wires are wet as well as the distrib cap
