Hello everyone! (tl;dr at bottom)
History:
I purchased my GTX in a pair which I went in on with a friend, a 96 and 97 GTX. I was told the 96 had a new engine (mid 2012) so I thought it would have less issues, but I was so wrong. After purchasing it need a new battery because the one it had was always flat, so that was a nice start. Go to grease it and find out that there is not grease fitting where the fitting is suppose to be! Buy one and grease it a decent amount. A couple weeks later blew a piston. Fixed the piston myself even though I've never worked on a jet ski but it turned out well and everything ran once replaced (). After that was fixed a hole in the exhaust manifold coming off the top end magically appeared - I honestly don't know how it got there - and the hole was deep enough to go into the cooling system and pump water into the hull of my jet ski. You see when I replaced the piston I didn't remove the engine out of the craft or the exhaust pipe coming off the top end and it was on the bottom of the pipe! So anyway I patched that with some marine exhaust patch stuff from Canadian Tire and seems to be holding well enough.
Today:
This year I was hoping my problems had stopped and it would just run, but it was not to be. A week ago it starts to cycle between 5500-6500 when at full throttle, so I changed the plugs and it went away for a day and then almost immediately came back. Check the plugs and they are black so I figured I'd adjust the carb's high and low speed screws. On going to do that I look and it there seems to have been a minor explosion of sand coloured liquid, with the consistency of a very thick oil, out of the oil pump! This could have only come from the oil pump as there was a spray on the lines in front of it and on the gas tank as well as dripping from the base where the pump attaches to the engine. I also noticed that the oil lines were still the old ones. Not knowing what to do or check in that area I just wiped it down and did nothing else and I haven't seen that liquid since. (I'll be replacing the oil lines tomorrow with new ones tomorrow if the weather holds.) So after adjusting the high speed and it running even worse I put them back where they were and opted for the low speed. The manual said tighten and then let off 1/4 so I did and that made it all worse with one exception - it stopped cycling between 5500 and 6500 and would mostly run at a steady 5500 sometimes dipping to 5200 and back every 30sec or so but never above 5500. Another thing that I noticed after adjusting the low speed screws was an increase in power on left turn (up to 6300rpm) and decrease on right turn (3500rpm) which wasn't happening before. Left cylinder has 120psi. Right cylinder has 123psi It also now hesitates when you go from standstill to full throttle.
That's where I am right now, I'm tired of trying random things and am looking for some advice! Thank you in advance.
Current Symptoms/Info (TL;DR):
- Max RPM 5500 and occasionally drops to 5200 and then goes back up
- Hard right turn = power loss (down to 3500prm) Hard left turn = power increase (up to 6300rpm)
- Switch fuel gauge from Fuel to RES and the ski doesn't run
- I messed with the low speed screws and am having a hard time finding where the sweet spot is again
- Hesitates from stop to full throttle
- After hesitation it will jump up to 7000rpm for around 2sec before falling to the regular 5500.
- Left cylinder pressure is 120psi Right side 123psi
- There was a one time sand colour liquid that sprayed out of the oil pump area and dripped down from where the pump attaches to the engine. Has never happened or leaked again. It's definitely still using oil.
