Quick Answer: How Long Can You Run An Outboard At WOT?

Can you run a short shaft outboard on a 20 inch transom?

If you set the motor back far enough without jacking it up, a short shaft will work on a 20″ transom..

How often should you run an outboard motor?

A typical outboard engine should provide 1,500 hours of run time, if it is properly maintained. Changing your oil every 50 hours of operation or six months will double or triple your engine’s life. Running your engine regularly, with proper flushing after each use, also extends your outboard’s service.

Will raising outboard increase RPM?

Raising the motor one hole will most likely increase the rpm’s by a couple hundred, you should gain in top speed as well.

How low should my outboard sit in the water?

For a propeller to best satisfy particular boating needs, the engine must be attached to the transom at the correct height. Over the past 30 years, industry standards for transom height have been developed: 15″ for “short shaft” engines, 20″ for “long shaft” engines, and 25″ for “extra-long shaft” engines.

Why is my outboard not pumping water?

Turn the engine off and check for anything, such as weeds or trash, which may be blocking the water intake. If a foreign object is present, remove it and restart the engine after it has returned to normal temperature. In most outboard motors, the water output is a small tube-like structure that can easily get blocked.

Is it bad to idle a 2 stroke outboard?

Yes it is bad for them to idle all the time. The plugs load up with fuel as well as that fuel possibly washing out the cylinders. Outboard engines were made to run at their suggested WOT, this is why we prop our boats for just that.

Is it bad to run an outboard engine at full throttle?

As long as an outboard is propped correctly, running at full throttle is fine.

How far below the bottom of the boat should the prop be?

If you have a short shaft motor, the top most part of the transom and the lower most part of the boat should be about 15 to 16 inches. For a long shaft, I think 20 to 21 inches is correct.

What happens if your outboard shaft is too long?

When the right length motor is hung on the transom of a boat, the cavitation plate (the large plate that extends out over the propeller) should be even with the very bottom of the boat. … At least if its too long you can raise the motor or “build up” your transom. Thats it.

Should I leave my outboard motor up or down?

When you park the boat for the winter keep the motor trimmed or tilted down, especially if it’s outdoors. This will allow all of the water to drain out of the motor’s cooling system. If it’s tilted up, some water may remain in the motor, where it can freeze and cause a cracked block or a ruined water pump housing.

How often should an outboard impeller be replaced?

Most mechanics and manufacturers recommend every 3 years more because you don’t want the bolts on your lower unit to cease up more than the actual wear to the impellor.

How long can you run an outboard on muffs?

A set of “ear muffs” or “flush muffs” was fitted around the engine’s gearcase to cover the water intakes, connected to a garden hose with a good water supply, and the engine was run for five to 10 minutes. But today’s outboards can be flushed using other, sometimes easier methods, without even starting the engine.

What happens when outboard is mounted too high?

Setting the Outboard Motor Height If the outboard is too low, it creates excessive drag, which cuts into speed and fuel efficiency. If it’s too high, the propeller tends to ventilate, losing its bite on the water and blowing out while turning and in steep seas.

Is Suzuki better than Yamaha?

How many hours will a 2 stroke outboard last?

2,000 hoursTwo-stroke outboard motors can reasonably live between 1,500 to 2,000 hours before needing major maintenance. It can last even more with proper maintenance and preventative measures.

Is it OK to run an outboard out of water?

You can run an outboard for a very short time out of water, but the impeller is running dry and will shred very rapidly.

How many hours is too many for an outboard motor?

I would start to think twice above 2000 hours or below 10 hours a year. More important is the way it’s been maintained – I would rather a well cared for 1500 hour 10 year old engine than a neglected 5 year old 50 hour engine.

How do I know if my outboard is 2 stroke or 4 stroke?

Here are some easy ways to tell if your engine is two-cycle or four-cycle:Look at the fuel cap. … Look for stickers labeling the equipment (e.g., “Four Cycle” or “No Fuel Mixing”).Look for an engine oil fill cap. … The Operator’s Manual will have engine fuel and oil information in it.

Will a jack plate increase speed?

A correctly adjusted jack plate may (MAY) result in a 5% performance increase, but usually somewhat less than that, so if your rig is already doing 50 mph you may see 52 on a good day. A jack’s real benefit is seen in terms of years.
