Hello, I have a 2002 seadoo speedster with the 2 stroke mercruiser in it, i've always had a non-working oil system, where the oil never came up from the big tank to the small reservoir. You many ask then, how did I ever use the boat, well everytime the oil thing blinked I would stop, unscrew the top one, and put oil in it. I don't use my boat much or for very long (partially because of this) but I've never spent the time to fix it.
Anyway, so I've decided i want it fixed. I took the tube off the engine, which I assume has to be an output of high air pressure, or perhaps low pressure. So I blew into this tube, and i heard air on the other side. Long story short, the cap that connects the external oil tube had a leak, screwing this shut caused no more leaks. Now I blow into this tube, and it becomes pressurized and holds the pressure. So now I take the tube off the top of the reservoir, I blow as hard as I can, nothing comes out. I take out the T thing up top, which I don't know what it is, a check value of some kind, it has an open tube, I assume a check valve for vacuum prevention reasons. So even with that off, no oil comes out.
Is my breath/air pressure a reasonable amount of pressure required to get oil to come out? A rise of 2 feet would only require 1psi to get oil to come out. Granted I pulled the tube out, so even moving it down to the same level, no oil. Which in a frictionless world would be 0psi. I do know that the air can go into the big oil tank, and verified that it's not clogged, when i took the cap off i blew in and felt the air. Perhaps the long oil drop thing is clogged.
So, should I just rip that tube out and see.... actually that's a fairly easy test to see if that tube is clogged. Since I had the tube that goes into the small upper reservoir in hand, i blew into it and it wouldn't let anything through. with the other tube disconnected it shouldnt' require that much pressure to accomplish this, unless there is another check valve somewhere, which is why i wasn't sure this test was valid.
Is what i'm doing making sense so far? I think i'm gonna go pull the one tube off the big oil tank and blow through it just to make sure it's not clogged, if it's not, then I would assume the oil pickup thing has a clog. Or do I simply not have enough air pressure to test this system? I was about to hookup the engine out tube up and start it for a few seconds to see if oil starts pouring out.
My main question, what PSI output is that engine output port, does anyone know? is it 1psi, 10psi? I can't imagine much over 15psi. I pulled the tubes off pretty easily, i'd guess it was pretty low, 1-2psi.
Thanks,
Ross
