From what I have read over the last couple of years, I fear that I'll need to rplace the coupler. Here is a brief summary of what happened.
Two weeks ago the boat performed flawlessly, including two nice little runs on plane with the admiral at the helm. (finnaly!:smt038)
Today we idle out through the no wake zone on extremely flat water. Once out, I slowly increased throttle but got minimal response. At about 1400 rpm it felt like the boat was trying to pull a loaded barge.
My first thought was a tangled mess of weeds, or worse, around the B3 props, that I could not shake loose. So I idled back into my slip & got into the water to take a look. I found clean & smooth (undamaged) props.
For what its worth the drive, and all fluid levels are fine. Ran the engine throttle only up around 2k a time or two & it sounded fine. In retrospect, the only other point I can add is that when I was idling out the boat seemed to be wandering abnormally.
So... If I understand things correctly, the B3 uses no rubber hubs to be "spun". So next thought is the coupler. Am I correct? Does my problem sound like the coupler has taken a hike? Is the coupler considered a wear item? I ask this because of the previous outings performance & we certianly didn't "hit" anything. My fear is that an engine alignment check 6 months ago may have prevnted this. Am I on the right track with these questions?
If my questions & assumptions are way off, well, I can take a harsh verbal bashing. As long as I can learn from it. Thanks in advance.
