Does this mean an engine should never run at wide-open throttle (WOT)? Absolutely not. Modern engines are designed to handle WOT. Also, during break-in going to WOT, as prescribed by the owner’s manual, is necessary to properly seat the pistons’ rings.
How long can you run an outboard at full throttle?
In the case of that engine, the manufacturer specifies that it can run at WOT for 30 minutes without any ill effects.
What RPM should I run my outboard?
When a boat is over-propped (the propellers have too much pitch), the outboard(s) highest achievable RPM is lower than the manufacturer’s recommended wide-open-throttle RPM, which typically is between 5000 and 6000 RPM.
How long can you run an outboard?
A typical estimate from the industry is that an outboards motor last around 1,500 hours of operation. Assuming the average owner uses their boat 200 hours a year, this would mean that the motor would last between seven and eight years.
Is it bad to idle a 2 stroke outboard?
2 stroke and 4 stroke outboards can work at idle without any problem. The alternator will not produce its rated output (18 A in your case) at idle.
Should I leave my outboard motor up or down?
It’s best to tilt your outboard up when leaving your boat in the water to prevent marine growth from forming and from corrosion eating away at its metal parts. That being said, there are some instances when you may prefer tilting your outboard down.
Will raising outboard increase RPM?
Greenwood says that moving the outboard up one mounting hole – or 0.75 inch – will allow the motor to gain RPM at wide-open throttle because drag is reduced. … “Or if you are already at 6000, raising the motor may allow you to move up one increment in prop pitch to stay at 6000 but go faster.”
What rpm do you run your four stroke outboard?
Most mechanics and engineers suggest the best cruising speeds are achieved at 3400 and 3800 rpm respectively.
Does Prop diameter affect RPM?
Why Propeller Diameter is Important
Diameter “usually increases for propellers used on slower boats and decreases for faster boats,” the manual continues. Further, “if all other variables remain constant, diameter will increase as power increases; diameter will increase as propeller rpm decreases.”
How long can a 4 stroke outboard run without water?
How Long Can You Run A Boat Motor Without Water? You are not supposed to run your boat motor without water, but if for some reason you must, between 2 and 10 seconds is the max time.
Which is better 2 stroke or 4 stroke outboard motor?
The fuel efficiency of a 4-stroke motor can be 50% better than that of a 2-stroke motor with the same HP. As for environmental concerns, 4 stroke outboards produce far less harmful emissions, which can be as much as 90% cleaner than those from a similar sized 2-stroke motor.
How many hours is too many for an outboard motor?
Fairly low hours for an 04 motor. If maintained correctly it can easily go well beyond 1000 hours…if it’s been rode hard and put up wet with poor maintenance it might not make it to 366.
How long will a 2 stroke outboard run without oil?
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.
Is it OK to run a four stroke outboard full throttle?
As long as you are propped correctly and can hit the upper end of the RPM range, [to run an engine at its maximum throttle all the time] is not a problem. Most smaller engines have two speeds, OFF and WOT. Very rarely does an engine wear out. Keep up with maintenance and you will be fine.
