The first shakedown cruise of my Explorer brought to light the need for a carb rebuild and a tune up. I completed those though did have the problem with the ball bearing in the accelerator pump channel.
Today was the 2nd shakedown which went really well. She started right up on the newly rebuilt carb. I was pleasantly surprised about that. Slow increase of the throttle brought smooth increase in power. I only pushed her to about 3000 rpm but she did get up up on plane. The lake had quite a bit of chop so I know what folks have been saying about the potential of being beat to death with a rough ride. will have to take her out a couple of more times to get used to it's behavior.
Maybe it was the chop but it seemed to feel like it was porpoising or maybe I was over reacting to the new behavior.....anyone experience anything like that?
I only encountered one significant problem that's easily resolved...crap in the gas tank. There wasn't a problem until we started to hit the chop which I'm sure stirred up crud sufficient to start flowing through the fuel lines. It first started happening at 2500rpm when it would take about 20secs before the fuel bowl would drain to the point of stalling. I checked the fuel filter (glass) and could see some crud in the filter. After a moment, it could be restarted and ran fine until 2500rpms again. No big deal.
But then the longer we stayed out, the lower the rpms would get before it would stall. Eventually it got to where we could barely idle but fortunately we were on our way back to the marina. Continued fuel filter inspection showed the filter (glass type) was completely clogged with a pudding like substance. Will pull it tomorrow and check it closer.
Other than that, the engine and outdrive appeared to run just fine. The next time I take her out I'll try pushing the rpm's past 3000k to see how she performs (when I have smoother water!).
In the meantime, suggestions on best way to deal with the crud in the tank. I know the obvious is to remove the tank but having just rebuilt the interior of the boat, I'm not thrilled at the prospect of having to take it apart to get the tank out. I will if I have to but I thought I'd check with you guys to see of there's an alternative.
