"Hey,

can anyone give me a suggestion how I could create some load on my 2-cycle/3-cyl/60HP motor out of water?
Also, I do realize using ear-muffs is not good for your motor. But still, would you give me some advice on how to load my motor please?

Thank you."
 
"nothing wrong w/muffs...if do

"nothing wrong w/muffs...if done properly....only way to load an eng that i know of,is a dyno,out of wtr...any other way,i would'nt even consider,..put it in the wtr."

Yep in the water or reverse the boat in the water and leave it tied down to trailer and you can load it up real well. But why?

"It dies under load.

And I think I checked everything: compression, carbs, spark, cleaned rotor.

Now when I calmed down (and I was frustrated) I think I noticed something or should I say, I'm suspecting that this was an "innocent" cause of the matter.

See, the thing is, when I bought this motor and I didn't have much knowledge of marine 2-cycle motor, I had the boat and the motor on the lake the very first day I bought it. The thing ran, very slowly but ran! It couldn't get out of wake because it ran only on 1 out of 3 cylinders. That's my point - it ran on one cylinder! It had enough power to rotate the freaking prop with 1 cyl!!! Now, as I cleaned everything I could in the motor and installed the filter (this is major suspect), I had 2 successful run-arounds on the lake cruising at 35 MPH! Until the 3rd fishing trip, when the motor would sometimes die before it picks up some power. And then finally would not even attempt to gain any speed and die right as I shift out of neutral!

Again, I cleaned, checked, replaced everything I could in the motor and I was ready to smash the darn thing and leave it on the curb.

Now, in the winter approaching spring here, I decided to flush the fuel out of the gas tank. I accidentally touched the fuel filter (mentioned above) with my fingers and I felt some gas. Hmmm, I thought...

It wasn't tight! Then it got into my head that is it possible that when the motor requires more power, and specifically for my motor (60HP), it does need a lot more fuel than in idle?! So, when trying to get that fuel amounts it could have possibly been sucking in the air instead of the fuel out of the gas tank that is located remotely!

So, to sum it up, I am sick and tired driving to the marina in a hope that it will work after I change something in the motor. That's why I asked about loading the motor when out of the water. Oh yes, it murmurs in neutral. The only time it dies is when needs some power.

Sorry for the lengthy one.

I thought I could use it out of water, bummer!

Well, thanks for heads up JWB.

I guess I'll have to wait till the ice breaks off the lake ..."
