Alright, took it for its first official test ride Thursday for a couple hours. Bearings in pump where still in great condition from what I can tell, pump oil definitely hasn't been changed in the 25 years or so, new orings and used about 6oz of the oil when filling it up, spinning the impeller and rotating the pump around to get all of the air bubbles out. When I had installed the wear ring, I just put some soapy water around the pump and on the ring, used some rotten deck wood and a brick and tapped in place.. lol
Loctite 518 on impeller shaft threads, between the nozzle and pump, loctite 243 on every other bolt on the pump, and the pipe sealant on the little fill plug on pump cone, neoprene seal didn't come in, in time for the weekend and was really itching to get it on the water, figured it was only 4 bolts to get the thing off and on so it wouldn't be a problem. Experienced 0 cavitation when on the water, although still going to put it on when it comes in. Greased up the driveshaft end also.
Ski ran great, when you get through the grunt of the bottom and the thing flies, probably a little low on HP from my lower compression but that'll probably be for another winter. Plugs are a nice brown color. Pipe was warm to the touch after the hours+ worth of riding so I'd say the cooling system is operating like it should.
Jumped some waves on the thing and ended up landing on the skis side with a mouth full of water haha, had to swim like 20ft to go catch after that haha. Submarining is also another thing this thing is so great at, honestly don't think any other ski could replicate the same feeling when riding this. Jettrim seat is super comfortable and the hydroturf mats are really nice on the feet. Noticed some hackjob on what looks like how you'd set the trim on the ski? Might play with that for a bit to see what it'd do one day.
After I brought it back from the water and it sat overnight, what looked like orange old fuel had came out the fuel tank vent line, probably some residual junk from when it had sat for its couple of years with the PO, fuel filter still leaks very clean so I don't have any worries with that.
This ski rocks!
