98 Seadoo Speedster oil question

[casims2000]

I took the oil out of my boat before winterizing last winter because the reservoir was leaking. I purchased a new grommet and had a friend put it in this past weekend. The oil was replaced and one of the engines was started to get the oil back through the line and into the engine. Did this cause any damage to the engine since there was clearly no oil in the line until the engine was started?

What is the proper procedure to get the oil back into the engine and how do I know oil is in the engine? I still have the other engine to do.

I'm not sure which engines your model has, but if it is the 787, then I am sure that is NOT the right way to do it.
Look in your shop manual for instructions on bleeding the oil lines.
Generally, you bleed the main line via the bleeder screw on the oil injection pump.
If the lines from the pump to the oil injectors got air in them, then you can leave the lines hooked up, but pull the pump off of the mag cover. Use a short section of fuel line over a driver bit on your drill to turn the pump until all of the bubbles are purged from the lines.
Then re-attach the oil pump to the mag cover.
Sounds harder than it is.

NOOOOOOOOOOOOOOO! Oil lines and pumps must be bled BEFORE starting the engines! Until oil is in the oil lines going into the rotary valve cover you must either use fogging oil in the intake and in the cylinder or major damage will occur! No different than running your car with no oil.

Download the service manual for any 717/720 powered ski and it will tell you how to bleed the pump. You should strongly consider replacing the small oil lines (pump to rotary valve cover), if they are original or painted then you won't see the oil flowing through them. When bleeding the pump easiest way is to remove the plugs, ground the plug wires, and spin the motor over with the starter. Loosen the bolt until oil comes out, then tighten it. Then keep cranking until the oil lines are filled.

Yeah you must bleed the lines. It also doesnt hurt to run a little premix during the first tank of gas.

This thread seems to be on the topic I am stuck on.. I've asked in my other thread but here it goes.

I have a speedster I bought, it sat for a while. No oil in the reservoir. The injection has been removed and the block has had the plates put in. I am running premixed. (this tank mixed it pretty thick)

But, For the RV/Case oil, is there a way to verify that oil is in fact making to the case and back?

Is this system just gravity fed?

Just to verify, the lines under the carbs are the input to the RVs and the lines coming from under the pipes are the outputs back to the reservoir?

Thanks..

The whole system is pretty much gravity fed. With the oil injection removed you need to loop the RV lines together with oil or keeps them hooked to the oil tank with oil. The large oild hoses that go to the engine block feed the RV and return..

Hey thanks howie... I am just so nervous about this oil system.. And i couldn't find any way to verify the RV is in fact getting oil.. I was thinking about unhooking the return line.. (The side under the pipes right?) and turn the eng over a few times to see if any oil spurts out.. I know with the premix I don't worry about the top end The oil injection lines have just been removed and plugged..

The RV uses very little unless you seals are leaking. That is why most people keep the lines hooke to tank.

Ahh, I see.. So basically as long as there is oil in the lines up to the case it's probably getting the amount it needs to keep it from crispy time?
