Good Afternoon,
I took my 2021 Fish Pro Trophy out the other day for the first time this year, water has been cold. While moving from spot to spot I noticed I had an issue when I started to accelerate, sounded like the pump had a cavitation instead of accelerating. I was able to get back to the dock but could only manage about 8 mph. I tried the IDF a couple of times to see if it had some debris but that didn't help the problem. When I got the ski back on the trailer and out of the water I raised the bucket to look for an obstruction but didn't find anything. I thought I might have a deep gouge in the wear ring or something bent on the impeller so I ordered replacement parts for those. Today I went to install the parts and when I took the impeller house out the impeller just fell on the ground, I didn't think this was correct since everything I had seen online showed you needed to use a vise and wrench to get the impeller off. I took a closer look at the impeller shaft and found the threads to be very messed up and the ones on the impeller were the same way. I took a closer look at the impeller boot and when it was installed at the factory the end that seals up had been pinched which allowed water to enter the area.
I am guessing the shaft finally gave out and the impeller didn't function properly after that, maybe in was moving in and out on the input shaft, which appears to be fine.
This part of the ski has never been apart, so all of this happened at the factory and not from the last time it was worked on.
Now I am ordering all new parts, Elastic flange nut, impeller shaft, angled bearing, oil seals, circlip, impeller boot, a couple new zinc anodes, and numerous seals and O-rings.
After this I will need to tackle the IBR Module Error message I am getting on the screen. Seems the IBR will not return to the down position after I raised it up to look at the impeller when I got back to the dock.
Sure am glad this issue didn't happen when I was 35 miles offshore.
