Seado Engine Oil

[s.yous]

Hello Everybody

I'm a bit new with Seadoos so bare with me.

I recently bought a 1995 Seadoo SP. I topped up the oil then I realized that I had put Premium 2-stroke outboard oil. Isn't a seadoo an inboard? Is this the right oil?

If not, what do I do?

Thanks

Simon

Drain the oil out before you have a problem. The oil you put in your ski was a TC-w3 oil. That is a huge No-No for a seadoo, and depending on what was in the tank already, they could react, and turn into a form of Jello. (plugging the oil system) Even if it doesn't react, it still won't provide the protection your engine needs.

Drain and refill with an API-TC oil.


Do a quick search, and you will find a bunch of threads on oil.

Correct oil

Thanks Dr. Honda

I went to buy some oil and the only API-tc approved oil says : high performance multi-purpose 2-cycle engine oil. It's made by motomaster and says that it's normally used for lawnmowers, snowblowers and any other motors.

Is this the right one??

I called a local seadoo service shop (snow city) and they said the tcw3 isn't a big deal but some don't like it. He said burn out that fuel then change the oil if I felt more comfortable.

I don't know. Should I burn it out and then use some of the above oil??

Thanks again

listen to Dr Honda... drain your oil.

i just did a top end rebuild because one of my pistons melted... and i lost a month of riding time and 600+ dollars because of it (a LOT more if you have a mechanic or dealer do it for you... as in 1200+ more in addition to the 600)

you can buy SeaDoo oil online and get it shipped to you, or probably buy it from the dealer you mentioned

I see a lot of guys on here running QuickSilver oil from walmart... thats another option

either way... drain it

You can do want you want but theres a reason people specify which oil to use in a seadoo. If it were me I'd take the safe route and drain it or take your chance with a $1000+ mistake

If a dealer told you it was OK to run a TC-w3 oil... they need to have their dealership taken away.

OK... truth be told... a single tank of TC-w3 oil isn't going to kill your engine. (but by no means do I recommend running it) But the thing I would be worried about is plugging up the oil system with what could form from mixing 2 types of 2-stroke oil.

It's up to you, but whenever I buy a used ski... the first thing I do is to clean out the oil system since a few $$$ worth of oil, and an hour of my time beats buying a new engine.

Ok will do

I'll flush out the old oil and put new correct oil.

Is there a step by step procedure, possibly video or pics, on how to flush my old oil?

Will the residue left behind from the old oil react with the new oil and cause problems?

Thanks

Generally... no. A small amount of residue won't cause an issue. But even if it does... the filter will pick up the remainder.

When I clear out a full oil tank... I start with a suction pump to clear the tank. (you can get them at harbor freight for about $6) then I disconnect the hose going to the injection pump, and let what's in it drain into a cup, and I do the same for the hose just below it, that feeds the rotary valve oil. Once the bulk of it has dripped out... hook it back up, and re-fill.

If you have a buddy with a Diesel car/truck, give him what you drain out. 2-stroke oil is great for a diesel's injection pump.

If you notice, any chunks, or sediment in the tank... you may want to flush it out. I like to use a little Kerosene, but any solvent that will evaporate will work.


Last thing... since the system will be empty, I would recommend changing the little oil filter, and the the 2 little hoses that go between the injector pump, and the intake manifold.



If you got that far... refill the oil tank, and then open the little bleed screw on the pump, to allow oil to fill the hose between the tank and the pump. (it's chrome, on the front of the pump, in-line with the hose) Then, start the engine, and hold the little arm on the pump to full, and watch for the 2 little hoses to fill with oil. (don't run it too long without cooling water)


With that... you will be done.

One more thing... whenever I work on the oil system... I like to mix the fuel in the tank at 50:1. That way, if there is still air in the injection system... it will purge out, and the extra oil will keep your engine healthy.
