Today I noticed something new on the engine. When i started engine at dock, I thought I heard something straight from the water, not the engine noise, sound like big bubble sound from the pump.
The first thing I thought is something got sucked in. Stopped the engine. And look at the back. (Didn't jump into the water to check the grill). Everything looked ok. So I restart the engine and went out.
In the no wake area, I pushed the throttle to 3000rpm, again the water coming out of the pump didn't sound what I used to hear.
This time I jumped into the water and checked the grill, it was clean. Weird, I was expecting weeds down there.
So I restarted engine, and pushed the rpm to 5000, just to quickly test if I need to bring the boat back. The boat got on the plane right away. So everybody was happy except i got a question mark in mind.
We drove the boat at 6000 rpm around about 20 to 30 minutes. Everything was ok. Highest speed i noticed on the meter is 35MPH. I also check the voltage meter, 14.2V.
So far I believe it was weed got sucked in, when I stopped the engine it just dropped.
Here comes another new one to me: after I idled the boat for about 2, 3 minutes (idle at 1300 stable). I pushed the throttle up to get to 3000 rpm. The speed reached 3000 rpm for a second, and dropped back to 2000 rpm, when I saw that I pull the throttle back right away, and push it up again, it stayed at 3000rpm no problem.
And kids wanted another "faster faster". So we got on the plane @ 6000 rpm @ 30mph for another 10-15 minutes. Then we went home happy :-D
So what possibly cause the little things today. I can stick to the weed story for now. But how about the 3000 to 2000 drop?
PS. I did try from idle to 3000 slowly a couple of times after, couldn't reproduce the problem.
