I took the boat out for about 2 hours and on the way back to the dock, I heard this vibration and the boat slowed down to approximately 5 mph at 1000-2000 rpm. I tried revving it up higher but it was of no use and couldn't go any faster - the rpm did go higher, and engine gets louder but the speed is the same. I limped at that slow speed until I got safely to the dock and towed it back to my garage. Here is what I have done.
1. I took the jet pump off, checked the spline and there were no shavings and the spline looks fine on both the shaft and the impeller.
2. I spun the impeller to see if there are any noise in case the bearings go bad but it was nice and quiet.
3. I also took the impeller cover off to inspect and it is nicely lubed.
I would like the forum's advice before I take the drive shaft off to inspect the other end. I don't have the Drive Shalf holder and I also don't have the Drive Shaft ring tool so I'll check the forum first before I spend money on getting the tools.
Thanks!
