Smoke Question???

[Seachallengermn]

Hello Forum,

I took my boat for the third time last week and it is running good for my standarts. One thing i noticed is that the exahust pipe on the left side releases a bit of white smoke. I am thinking that this might have to do with the Oil & Gasoline mix.

Does anyone can help me to let me know if this is normal? Just want to point out that this is my first summer with my boat and the gasoline in the tank is at least 7 months old ( Long Winter) is there any additives that i can use to clean the fuel system?

By the way my boat is a 2000 Challenger 1800 ( One Engine).

**** I have to say that this forum has been VERY,VERY helpfull ******

What I would suggest is to NOT add anything to the fuel. I would just run it out of the jet boat and add clean fresh fuel when it gets to about 1/2 full. Run that out and than I would also change the plugs with the fresh fuel on the next fill up. also here is some information on the proper oil and fuel recommended by seadoo.

Use High quality low ASH API TC Injector oil.
Do Not use NMMA TC-W, TC-W2 or TC-W3 outboard motor oils or other ash less type 2 cycle oil. Avoid mixing different brands of API TC oil as resulting chemical reaction will cause severe engine damage. Never mix Mineral or synthetics oil together.

Never use fuel containing more than 10 % alcohol,( Methanol or Ethanol) as severe damage will occur. The minimum of 87 octane is recommended for most engines.

I hope this helps.

Karl,

Thank you very much for the imput.

Let me start saying that the oil that I am using is the one that you are telling me not to use. (TC-W3) This oil was suggested by the previous owner .

Can i just use most of the oil in the reservoir and then add the correct one or do i need to flush it and then add the right kind?

Do you have any suggestions for Spark Plugs?

Thank you

here is what seadoo recommends to do when changing out oil with injector;Here is a step by step to the oil pump oil lines;

After you drain the oil from the oil lines and refill them, you have to be sure there is no air in the lines when the engine starts up or it will cause the engine to seize up. You need to fill the oil lines back up with oil. To drain the oil from the Rotary Valve Chamber, use a shop vac to suck the oil out of the hose…it’s the one that is 3/8” diameter. I attach the empty lines back to tank and fill the tank. The oil line going to the oil injector pump attaches to a elbow fitting on allows the oil to flow to the pump. I let the oil drain into the oil line to the pump first and put a small cup at the end of the oil line, to catch the oil coming out of the end of full line. Attach the full oil line to the elbow on the oil pump. There is a bleeder screw on the pump. Lay a rag under the bleeder screw. Open the bleeder screw till the pump has oil coming out. Tighten the bleeder screw. Be sure the oil is full in the small 2 lines also. Let the oil seep out the ends of the small lines to fill the lines as best as you can. Connect the 2 small oil lines from the pump to the carburetors. Where the cable is connected is a Disk,(pump lever) that the cable is attached to. Check that the mark on the pump aligns with the mark on the disk. Apply the throttle with the ENGINE OFF and check that the cable is in sync with the oil injector cable. They should move open and close at the same time. To bleed the 2 small lines and get the bubbles out, start the engine, on the water hose. DO NOT APPLY THROTTLE. Let the engine IDLE. Turn the Disk,( pump lever) that the oil injector cable is attached to, to full open so the air bubbles travel to the carburetors and leave no bubbles in the line. Don’t run the seadoo for more than a couple minutes on the hose.
For the Rotary Valve Gear Shaft, attach the hose on the tank and allow the oil to fill the hose and attach it to the case. Recheck all the oil lines and be sure they aren't leaking any oil. If you still have any questions give us a shout.

Use NGK spark plugs BPRES gap to .021in or .55mm

The Merc manual recommends the NMMA TC-W3 oil

I was reading in the manual that merc recommends the TC_W3 stuff. Does Seadoo recommend something different for the 240 EFI or the 210 m2 engines?

No.....

No, follow the Mercury oil standards for your M-2 EFI optimax motor. This motor was used in the Seadoo's from around 2000 to about 2004, until the 4-TEC engine started turning out 255 hp and the Optimax topped out at 240 hp.

Seadoo does not have OEM mechanics working on these boats. You'll need to have it serviced by your local Mercury. And please, use the Mercury line of products on it for maximum engine life.

We do carry the M-2 shop manual in the library if you'd like to get a copy.
