How do I know if my outboard thermostat is bad?
Symptoms of a Bad Thermostat
- Engine overheating, particularly at idle and low running speed.
- Engine going into limited power or slow mode to mitigate against overheating.
- Increased fuel consumption.
What are the symptoms of a stuck thermostat?
Thermostat failure symptoms that you should know
- High temperature readings. The main symptoms of a failing thermostat are related to engine overheating.
- Erratic changes in temperature.
- Leaking coolant.
- Increased fuel consumption.
- Unusual noises.
How long can you run boat on muffs?
For larger engines, use the flush port or a set of flushing muffs. Water pressure should be set to one-half or more to ensure adequate flow to the intakes. The engine should be run for five to 10 minutes.
How long can you run an outboard at full throttle?
According to David Meeler, Yamaha’s product design manager, “You only have about 15 seconds of cumulative dry running time before your impeller starts to fail due to excessive friction. That means if you run your outboard dry for three seconds five times, it will likely fail.”
How do you read Honda outboard serial numbers?
The frame serial number is found on or near the stern bracket, stamped into a metal plate. The number uses the form “BXXX-XXXXXXX” and may also be referred to as the product identification number or Vehicle Identification Number (VIN).
How do you read Honda engine serial numbers?
To find the model number, look for a model number sticker on the engine. All Honda engines model numbers start with the letter “G,” such as “G100”, “GX610”, or “GXV160.” This is the base engine model. The engine model and serial number should be adequate for most of your needs.

Is it OK to drive with a stuck open thermostat?
Can I Still Drive with a Bad Thermostat? The easy answer to this question is no. While your car may be physically able to move and get you from Point A to Point B, you will want to refrain from operating your vehicle. This can lead to more parts of your vehicle being damaged, especially if the engine is overheating.
What will happen if thermostat is stuck open?
If the thermostat becomes stuck in the open position, there is continuous flow of coolant into the radiator causing the engine to run cold. Overcooled engines run inefficiently, which leads to increased fuel consumption and higher emission levels and engine parts enduring more wear.
Do I need to flush outboard every time?
Most outboard manufacturers recommend a freshwater flush after every use in saltwater to clear the cooling passages of salt residue and scale that can accumulate and impede the flow of vital cooling water through the engine.
Can you put your boat in gear with muffs on?
Yes, you can put it in gear. VERY LOW to show that the prop will in fact spin but you can not rev the motor “muffs” will not be able to suck in enough water.
Should I run my outboard at WOT?
Because propeller pitch plays such a significant role in the performance of an outboard or sterndrive, it’s necessary to run a Wide Open Throttle (WOT) test every time you fit a new propeller. Whenever you purchase a new outboard or boat, it’s wise to perform a WOT RPM test.
What RPM should you run your outboard?
Most mechanics and engineers suggest the best cruising speeds are achieved at 3400 and 3800 rpm respectively.
What year is my boat by serial number?
The number is the last digit of the year in which the boat was built. “4” in this case designates 2004. 04: This indicates the boat’s model year.
Where is the serial number on a boat motor?

How hot is too hot for an outboard motor?
Two-Stroke Outboard Engines
The thermostat opens at 118F – 160F (47C – 70C). The overheat warning activates at 160F (70C).
What temperature should my outboard run at?
Engine oil will run hotter than the coolant, somewhere between 230 and 260 degrees Fahrenheit if the engine is fully loaded. If it is not fully loaded, and especially if the weather is cool or if the water temperature is cold, the engine oil will run much cooler.
Will an engine overheat without a thermostat?
Running an engine without the thermostat can cause the engine to overheat due to the coolant passes through the engine too fast and will not let the coolant absorb the heat from the engine.
