Easy way to check spark is to have the motor running at fast idle and use a pair of pliers and slowly pull off each plug wire and listen for a change in the engine tone and listen for a crackle as the spark jumps from plug wire to plug. If you have good compression and spark on both most likely culprit is water or dirt in the carb Yamaha 30AE loses power at full throttle 09-07-2015, 08:14 AM 30hp model AE, loses power at 3/4 to full throttle. It seems to be a fuel issue Spun Prop One possible reason why boats no longer achieve appropriate speeds at full throttle is a spun prop. This occurs when the bond between the propshaft and blades are broken, which subsequently causes the rubber insert to spin independently
. Burning premium gas rarely offers any benefits in performance or fuel economy in these engines. HOWEVER, premium gas does have higher octane rating and the added benefit of additional detergents and cleaners Correct. There is basically 3 ways to do this. 1, with the boat in the water at full speed 2, with the outboard in a test tank with a test propeller on it, running at max rpm. Or 3, outboard in a test tank hooked up to a dyno, running at max rpm. Those are the only 3 ways to test it
To access the fuse, unscrew and remove the electrical cover on the top of the outboard and remove the fuse holder with a pair of pliers. If the connection at the center of the fuse is broken, the fuse has blown. Replace it with one of the same amperage, as listed in the Specifications section of the Yamaha outboard owner's manual. Step If your outboard engine is sputtering at any speed, idle or full throttle, it could be the result of several common malfunctions. You may need to make a few timing adjustments or replace a spark plug, or you may need serious mechanical inquiry At what point does an outboard wear out? Using the 150hp Yamaha on the watertaxi at 8600hrs+ and assuming an average of 1000 rpm, we can see that millions of revolutions did not wear it out even with less than recommended maintenance. In reality running your engine at WOT will not decrease its usable life
If your outboard motor isn't running at its best, check the fuel vent on your portable tank to make sure it's open. Photo courtesy of Attwood. If your boat doesn't have a portable tank, but instead an integral tank with a fuel vent that's plumbed to the outside of the boat, inspect that vent jstarzy. posted 06-04-2012 11:10 PM ET (US) I anticipated a nice ride from Morgan NJ to the Navesink in Rumson in the Montauk, [but the Yamaha 90-HP two-cycle outboard engine] acted up. [The Yamaha 90-HP two-cycle engine seems to have] no power over 3,000-RPM. The throttle movement from 3/4 to full did nothing under load, but [the engine speed. Hello, I have a '91 Yamaha ProV 150 on a Ranger 351V. I've had this boat for about 2 years and have been happy. The hole shot to planing used to take about 3 to 6 seconds depending on extra weight (fuel, passengers). After about a month ago, after a day of fishing, I was headed back to th.. Your outboard engine's ignition system is responsible for igniting the gas, firing up the engine, and keeping it running. If your outboard will not throttle up or your outboard motor dies at idle frequently, chances are you may have problems with your spark plugs. How to Fix It
This video will teach you how to correctly care for and run-in your brand new Yamaha 4-Stroke outboard motor to ensure the longevity and legendary reliabilit.. . It could be a water issue clogging up your filters. Saw the same issue on a 70 about a month ago. If it runs fine off a deck tank, change out all your filters and consider draining off what you have in your tank Watch our Yamaha Outboard Fuel Pump Issues video above — in which we guide you through an outboard's fuel system — to troubleshoot possible issues that may be causing fuel pump problems. NOTE: Although we're using a Yamaha 250HP motor as an example, the fuel system will be very similar on any modern outboard, regardless of brand or model
Honda and Yamaha still recommend running in their four-strokes at low to midrange throttle for the first 10 hours, after which the oil and filter must be changed. However, OMC recommends the same procedure as its two-strokes, one minute of WOT operation in every 30 after the first hour, while varying throttle settings every 15 minutes Yamaha outboard power loss - Help needed! I have a 2005 Yamaha F150 TXRD 4 stroke outboard engine that is having some serious issues. It was running perfectly until about 2 weeks ago when it suddenly started to really lose power at higher revs and quickly got so bad that I cannot even get my boat up on plane anymore In any case, while cruising at about 5000 rpm on a plane, I had a sudden loss of power so that I could no longer stay on a plane. The engine idles ok, and, in neutral, I can run it up the full rpm range without difficulty except for occasional stumbles. After everything I tried, the boat does not have enough power to stay on a plane Hi guys am seeking help with my 1997 Mercury 2stroke 9.9hp outboard it runs great in idle and reverse but as soon as you click into forward as you increase speed it'll kick in but then start to decrease speed after about 10 seconds but sometimes will run fine for 10 minutes or so but then it reduces its self to about a walking pace ! Yamaha advertised its outboard motors as high-power engines with unmatched reliability and durability. Date Although Yamaha created a kit to try to correct these problems, it has not issued any technical service bulletins or recalls regarding the motors
Why does my outboard stall? Your outboard may be stalling & running out of fuel due to three issues. Either the lift pump has failed, the boat is out of fuel or there is an air leak or blockage somewhere in the fuel lines running fuel from the tank to the engine. There are several methods to troubleshooting a stalling outboard engine . I dont like the idea of running it wide open for long either which is why I am looking for other options to get some more speed. I am not sure what prop it has but I know the book says to size it I should run the motor full and straight and be tached out at around 5400 rpms (mine goes to about 4300 before it bogs down) But note that these engines maintain a respectable horsepower-to-weight ratio. The Yamaha F425's ratio of 0.44 is about the same as it is for an F250 V6, one of the most popular outboards of its size on the face of the planet. And the 627sv manages an eyebrow-raising 0.57, one of the top power-to-weight ratios on the outboard market today
. I can get it to 2.8 to 3.5 mph trolling speed and it runs a little rough while trolling and if i go any slower it will stall and while trolling i have to hit the choke every 15min or it will stall or as it feels like its gonna stall i throttle up a hair Regulator/rectifier to convert the coil output into regulated DC current suitable for charging the battery. The good news was that our outboard motor, an 8HP Yamaha 4-cycle (model F8MLHC), already had generator coils installed (on top of the flywheel) at the factory. The manual states that the output is 80 watts maximum, or 10 amps at 12 volts DC Squeeze bulbs have a check valve at both ends that allows fuel to only flow in one direction--from the tank to the engine. When the outboard is running normally, the engine's fuel pumps create a slight vacuum in the fuel hose. Atmospheric pressure in the tank through the vent pushes the fuel from the tank to the engine The ignition system on outboards consist of stators, triggers, and power packs.The most important thing on outboards is to check the timing advance, if the timing is off even slightly it cause a a myriad of problems, it could not start, cut out, run good to some RPM and then die out. To do more in depth testing you will require a DVOM and the.
I have the owners manual in front of me and it gives 3500-4500 as the full throttle operating range which seems quite low compared to most outboards. At some point Yamaha tuned up the 212 ci 8hp to become the 9.9 that is currently sold but so far I have not been able to find what year that took place Moreover, the maximum power of solar charging is not high enough, so it is impossible to support long time running at full power. It is important to point out that the 3HP petrol outboard is not so easy to achieve a long running time, because it generally does not have an external oil hose, so it is more troublesome to refuel the engine hanging. At initial start-up, everything runs fine. I can run the outboard for 2-3 hours with no loss of speed or power, but if I shut the motor down or if it runs out of gas, I will have to wait for 20-30 minutes before it will restart. Runs good on all cylinders. Any thoughts on what to check for? Outboard Spares Response Hmmm, interesting I already loved my Yamaha outboard, but the Power Pay program has taken that to a whole new level. Q - Yamaha Power Pay isn't only available to the pros; Bassmaster Opens, FLW Toyota Series, select team tournament trails, saltwater, college and even high school anglers are all eligible for bonus earnings Most outboards I found are pretty much just set up right from the factory, so it's not something to really worry about. But if someone has played with it then be aware of it. Now we know the timings right I'm going to look into other reasons why that outboard might be sort of popping and sneezing and backfiring a bit like that

Even with a modern engine and oil, it's critical not to over-shoot that initial oil change, said David Meeler, Yamaha marine product information manager. Think of it as the first pit stop of a long race.

Hi, I have a 4HP 1980s vintage Mariner outboard (Yam built, 6E0 engine, earlier shear pin drive prop) which is used on a tender to get out to our mooring. Once running, the engine is fine. However it is a pig to start, bad enough when cold but seemingly even worse if it was already used a.. Old fuel is usually the biggest cause of problems. In my limited 1st hand experience with an outboard that has been sitting up, you need to change the water pump most importantly. The water pump is kind of a plastic gear or impeller that gets brittle & dried out over time. Upon attempting to run this motor, the impeller is likely to. Will An Outboard Run With Low Compression. Yes, an outboard will run for a little while with low compression. If the compression is too low though, it will not run at all. Here are all of the things that you need to know about low compression on an outboard engine, what they mean, and how they affect the running of the engine
Overheating an outboard often stresses these water-cooled regulators, and electrical problems or failures may develop soon after. Certain outboards use the overboard water telltale indicator as the cooling system for the regulator. To avoid expensive damage it is important not to run these outboards with mud or sand restricting water flow No noise nothing. Took it to a dealer and was called two days later saying the power head was shot. Still under warranty so Yamaha sent a new power head with new oil system and also installed a water seperator for me. was all done in one weeks time. however I do know this new power head does not run a fast as the 1st one Yamaha. Yamaha gives three choices — with a flush bag, muffs, or hose-port connector and says all three methods work equally well. Bag and Muffs: Engine should be vertical, run no more than 800-900 rpm in neutral for 15 minutes with the prop removed. Be sure the engine is receiving cooling water (by checking the overboard indicator)
6. Wipe down and spray all accessible mechanical components and moving parts with an anti-corrosive. Some of the best options are lubricants such as WD-40 or Quick-lube. Be sure to lubricate or grease all the moving parts such as the pivots, shift mechanism, throttle cables, carburetor valves, etc Sometime in the 1970's, I think it was Yamaha brought out two stroke small outboards that ran on 100:1 fuel. With no engine changes at all, Evinrude and others decided that their engines, previously 50:1, would now run on 100:1 but with the added proviso that it was recommended that 50:1 be used for commercial use Yamaha's 432-cc all-new 20-hp portable outboard built on the same award-winning platform as the F25 and sharing its SOHC in-line design and streamlined intake manifold delivers solid power.

These engines meet year 2006 emission.
2. Check the engine idle speed after the engine has been warmed up. 3. Operate at trolling speed. 4. Run the outboard motor for 1 hour at 2,000 r/min or at half throttle, then for another hour at 3,000 r/min or at 3/4 throttle. 5. Check that the outboard motor does not tilt up when shifting into reverse and that water does not flow in over the. With computer controlled ignitions for smooth running, quick acceleration and excellent fuel economy, these outboards are the perfect power match for the small tinnie or inflatable craft. Of course, being a Yamaha four-stroke, they are not only extremely reliable, but are cleaner, quieter, smoother, more fuel efficient than their two-stroke.

At full speed, the Spirit will only last for about 90 minutes on a single battery. With a 12 foot boat, you can go about 9 km/h - not bad for a relatively low power engine.

If you run the Spirit on 1/4 power, you can keep it going for 6 or 8 hours Yamaha will offer the new 4.2-liter Offshore F-series outboards rated at 225, 250 and 300 horsepower.
