Hi all, Tomorrow we will be taking the boat (96 Speedster) out for our one and only ride this year. We just purchased it, and when we test drove it there was some low speed cavitation. Basically after slowly pulling away from the launch when you first give it throttle you hear the cavitation sound and the RPM's go up but the speed does not increase that much and the bow stays up high. Then after about 10 seconds of giving it more throttle all of a sudden the cavitation noise goes away, the bow drops and the boat takes off like a bullet. I've taken a look at the impellers and wear rings through the water inlet, and they seem to look okay to me (but I am very new to this). I was hoping to get good pics and post later to get others opinions. Also, the wear rings were replaced by previous owner a couple years ago, and the impellers were serviced at the same time (though I know it's what they have been through that's important, not time). Anyways, after reading many posts on the forum it seemed like I might have worn out Carbon Rings. When I grab the Ring's/Boot's I can easily move them around. I am hoping to change the Carbon Rings this Fall and get a better look at the wear rings and impellers then and do what's needed to them as well. Yeah, I've been doing a lot of reading on here and the Shop Manual. This is all completely new to me, but I love to work, have no problem getting my hands dirty, and I really want to learn.
Anyways, I was able to get a couple C-clips at my local Sea-Doo shop and I replaced the Floating (Stainless) Ring O-rings when I had a thought. I've read a post from Dr. Honda (I learned very quickly to pay very close attention to everything he posts!) about the temporary fix/trick where if your drive shaft has more then 1 groove for the C-clip then you can increase the pressure between the Floating Ring and the Carbon Ring by using one of the closer (to the Carbon Ring) grooves. Unfortunately my Speedster only has the one location, but I had a thought. Is there any reason why I could not push the Floating Ring toward the Carbon Ring far enough that I could move the O-ring out of the groove (toward the Carbon Ring) and then install the C-clip into the groove behind it. I figured this would give me a little more pressure between the Floating Ring and Carbon Ring.
Does my idea make sense, and do you think it's okay to do? Again, this is just a temporary fix, and is as much to serve as a test to see if the cavitation seems any better (which if I'm actually starting to understand some of all this, may indicate that indeed my Carbon Rings are worn out).
Thanks!!!
