Well here it goes...
My recent purchase has turned out to be all sorts of problems... First it was the cracks in the bottom from a previous owners attempt at reinforcement, and now a bogging issue after pulling the motor and hauling it 200 miles to college. This was my first engine pull on a jet ski, but I felt like I did a good job labeling everything and putting all parts back in their right places. The motor actually started and revved correctly after re-installing the motor. ( I even cracked open the celebratory first engine pull beer)
When removing the electrical box, I found about an inch and a half of water waiting inside for me. I let it air dry in front of a fan over night to insure it was completely dry before covering it all back up. After that, I took electric grease and smeared it all over the exposed connections. I pretty much smeared that stuff everywhere I could.
I hauled it 200miles and now it will not run correctly. The problem may be something I did in the engine pull, but I cannot think of what it was? Something vibrated the wrong way? Maybe the electrical went bad after the road trip?
The only thing that is different between before and after the trip was gas. It has a half tank from the previous owner in it. He said it was 3 months old, but when we test drove it, it ran fine. No sputters or hesitation. ---- I diluted it with some premium fuel and quicksilver premium 2-cycle outboard oil (read the outboard part didn't matter). Previous owner mixed at 32:1, I put in 40:1. Is it possible for the oil I poured into my 5gal gas can to not mix in properly? I haven't been around too many 2-strokes in my day.
ABOUT THE SKI:
95' FX1
milled head - had a compression test done before I bought it. 165 & 168
aftermarket F/A
ProTec ride plate
Jet Dynamics intake grate
Low pitch impeller
WHAT I HAVE DONE SO FAR:
Cleaned fuel filter - some small debris, but it blew out without too much constraint. It consistently holds a 3/4 to full fuel level.
Cleaned Carb - had some junk in it, but no water. Diaphragms looked good. ( Previous owner replaced them all this past year apparently)
Held the spark plug boots down - not sure if this does anything, but figured it might help if its a bad connection.
Pulled spark plugs - they are both pretty black. This will be the next thing I replace.
Flashlight in the spark plug hole - looked very oily/gunky. Hard to describe this. Kind of a bedliner look, but not rough...
HOW IT RUNS NOW:
It revs up like normal but then hits this "wall" of a bog. It will just sit there and bog way down, but will not die. I put it in the water (how i found the problem), and it would only take me to maybe 3 to 5 mph. Not even enough to raise the nose up any.
After having it not run on the water, I pulled her onto the trailer and had the same results in the driveway at home. Same constant bog when hitting the throttle.
Hopefully this is enough information to get a clear understanding of where I'm at.
I probably overlooked something, so anyones suggestions are greatly appreciated.
Thanks,
Mace
