587cc Oil Injection

[Marcusknight23]

I have a pair of 1994 Seadoos with 587cc that I got recently. I have been using one of them and have put maybe 4-5 hours of use on it at most and have gone through maybe 10-12 gallons of gas. I would say 40 percent of the run time was at WOT and the rest is either about half speed or just over or under. My concern is that the oil level in the oil reservoir has hardly moved at all. I dont get it. I would think that if the engine was not getting oil, the engine would already have blown or not be running.

Thoughts?

I made a short video of my predicament. Again the oil level doesnt seem to have changed in about four hours of use. Check this out"

If you start the engine, and reach down towards the front of the engine, you will see the oil pump connected to a metal cable going to the carb. When you press the throttle, you will see the pump control open up.

With the engine running, move the oil injection control full open, the engine should smoke a lot.

The injection does not use a lot of oil. I think my 95 GTS does use more than what you are describing...

Great idea on moving the injection lever. I will try that!

New question: Many people claim the oil hoses get brittle and old and need to be replaced. I have a hard time telling if this is the case on my Seadoos or not. But perhaps, could it be the two SMALL little hoses that could be at fault and causing an oil pump disruption? Or should I really be paying attention only to the bigger oil feed line from the oil tank?
See my youtube video if you want to see my setup.

The large line is the main line from the tank to the pump. The two smaller lines are the individual feeds from the pump into the intake for each cylinder.

The large line, if everything is original, is soft and has a filter inline. If that line is hardened up, but not leaking, then it's probably not an issue yet. I have an all factory 94 SP just like yours and the lines are flexable just like new. The smaller lines feel more rigid, but again, unless they are leaking don't worry about them.

Confirm the cable going to the oil pump is adjusted properly and is mechanicaly sound. It is a shorter cable that has a regular barrel on the injection pump arm end and a threaded fitting with a jam nut on the other end that ties into the throttle arm on the carb. The oil injection arm has a small "tick mark" on the face that should line up with another tick mark cast into the oil pump body. Use a small mirror to find the marks, they are both located where the pump arm pivots on the pump shaft on the front of the rotary valve plate jusst under the carb intake air box. Lightly pull the throttle lever to remove all throttle cable slack, the oil injection pump marks should line up jyst as the throttle plate starts to move. In other words, the oil pump marks should line up just as the motor gets enough throttle to come off idle and start reving. If it needs adjustment use the threaded end with the jamb nut to adjust the oil pump.

The SP did not use a ton of oil. The oil tank itself is quite large, a hair over a full gallon if i recall correctly.

Go check the oil pump marks and get back with us.

People dump crap oil in those things over the years. The mixing of the cheap brands will(has in your case I believe) gel in the filter. This clogs the oil filter up and slows, eventually stops the flow. Be sure to change that filter for a new one. It's a fairly easy job and they are not expensive. http://www.ebay.com/itm/2-x-Seadoo-...ash=item1c88c5ced9:g:kkoAAOSwIjJZRm5X&vxp=mtr

Just a visual of what Matt is saying. This is what I found in my oil filter when I bought my boat. Previous owner was using the wrong oil.

 

[AKnarrowback]

Check that filter.

And replace the small 3/32" oil lines. They do fail and will destroy the engine.

 

[Marcusknight23]

Well I took off the intake and have been inspecting the oil lines visually. Is there a way to tell if these lines are becoming "brittle" and "collapsing" like so many other people say happens? I have new hose but I thought I would show this to you all first. Also am wondering if the nozzles could be gummed up with last owner used wrong oil perhaps. I did replace the oil filter.

Here are some pictures of small oil lines on pump:
