Question about Sport & Outdoor - Others
Hello, I have had this engine for 6years and day before yesterday it happened. Only three guys on boat, full throttle and engine took only <3000rpm(normal about 5000rpm). I made it to shore. I changed the filters and looked that plugs were fine. Yesterday a new try, again same effect except the engine stalled completely and didn't start again(three hours of engine checking on lake). I had to paddle my way to shore.
I again changed the filters, looked that fuel is coming to engine, change the spark plugs and caps. Now it starts, but when trying to load the engine running it against ropes on pier, it stalls right away. Idle is fine and in neutral position engine takes over 5000rpm. When trying the to load the engine with reverse, it works fine. Runs about 2000rpms with full throttle=>should it run faster? I affraid going on lake if I cant first succesfully load the engine on pier.
Any tips how to proceed?

Hello, I would start first, make sure ex pipe is open . Then I would check the pick up coil, ohms should be 390-590 on a 300 KLF. Do this test before u start the bike Then start the bike and when it quits running check the pick up coil ohms. If good move on to the coil, If good then I would say good chance CDI is bad I hope this helps

Your carburetors need to be cleaned. The pilot jets are at least partially plugged.
If you are comfortable doing this yourself, you need to remove the seats, fuel tank, and air induction system before you will be able to get the carbs out. Be carefull when removing the fuel tank, there is a wire harness that will need to be un plugged from it to remove it. The wire harness plug runs under the plastic tray under the seat. There are 3 plastic rivits that will need to be removed to get to the plug. The carbs come out as a pair, and can be tough to get back in the boots.
You need to remove the float bowls, remove the jets, and blow carb cleaner and compressed air through them all. The pilot jets are most likely the only culprit, but you might as well clean everything if your going to all the trouble. You should also blow carb cleaner and compressed air through all of the other passages while your at it. Make sure that you can see through the jets and there is no debris left in them. Make sure to clean the floats, needle valves, and float bowls as well.
This happens when the bike sits for long periods. The fuel we get now days has a very short shelf life before it goes bad. Fuel oxydizes over time, and it happens even faster in a small amount that is vented which is exactly as it is when its in the carburetors of a motorcycle. When fuel oxydizes and evaporates, it leaves a gummy mess behind. The pilot jets are the smallest passages that sit in the fuel, so they naturally plug first.
You can prevent this by keeping fuel stabilizer in your fuel when ever the bike will be sitting for long periods of time. Myself personally, when I store one for the winter, I like to leave the carbs empty.

the inside of the prop has a rubber between the prop itself and the inside splines to act as a shock absorber,say if you were to hit a rock. that rubber had spun out and the splines are turning inside the prop. the prop is screwed. seen it 100 times before.

Not familiar with that specific motor but had similar vintage smaller HP Johnsons. From my experience it sounds like it could be that the high speed carb adjustment is too lean. What I would try is running the backing off the high speed screw 1/4 turn to 3/4 turn, then test. If works better, screw back in in 1/8 turn increments until the problem recurs, then back out 1/4 turn and leave it there.
