2004 GTI - low RPM and oil warning light on

[Dgraber]

Guys,

Let me just say that I am a veteran boater but a virgin PWC owner. I recently bought a 2004 GTI very low hours/use (according to owner) but the boat appears to be like brand new.

I have run the boat with no issues since purchasing in May 2015. While on vacation last week (of course) I noticed my engine oil reserve was getting low - not empty by any means 1/3 full...but obviously never want to run out of oil.

I purchased a gallon of Mercury Quick Silver 2 cycle oil (told it was the best to use) and dumped it into to the oil reserve tank topping it off. Went to marina filled up with 93 octane gas (as usual) and off I went. Out on the lake the PWC ran perfectly as usual...and then...it slowed and eventually would not run at full RPM. No warning lights came on - no white smoke - I could smell the 2 cycle oil smell as usual...just would not run up to high RPM. I turned off the PWC - removed Lan-yard - plugged back it and pwc starts perfectly no lights - but no power.

I went back to houseboat - changed out the plugs (of course) pwc fired right up no problem...no white smoke no lights. I idled out...slowly accelerated and the pwc came right up on plane with normal RPMs - problem fixed!!! until about 50 yards pwc stopped oil light came on and now pwc will not start...DAMN!

Any body have any thoughts of what damage I may have caused??? - I have done research on 2 cycle oil and data is all over the place. Not sure where to turn next - other than pull the plug an use as an anchor....

Thanks guys!

What version do you have? Carbs or injected?

 

[Dgraber]

Carbs. This is the little 717 rotax engine.

OK....


Well... since the oil light came back on... is there oil in the tank? Maybe one of the rubber grommets gave up, and the oil is down in the hull.

What did the old spark plugs look like? What do the new one's look like?


Regardless.... with a 2-stroke... I like to start with a compression check. That will tell us a lot right away.

I have a 2003 Rxdi and my low oil warning light is also warning me of low oil but has a full tank. I have replaced the sensor and still does the same thing. Any thoughts? It just started doing this and it won't get out of limp mode.

Did you know what brand of oil was in there in the first place? Seems like we are not supposed to mix brands. I am sticking the the BRP Synth oil to be on the safe side (but yet, I blew an engine...). If you want to know how many hours are on your engine, a BRP dealer will tell you right away unless you buy your own computer kit. Mine went dead at 133 hours. Short lived but I bought it used.

And I agree to the compression test.

I don't know the brand that was in there. But it ran for a few hours then went into limp mode with low oil warning light. Even with a fuel tank

Also it has only 144hrs

First, you have a low oil warning: this could be a faulty sensor. But it doesn't make sense because your ski is actually experiencing issues. And then there is the limp mode. Correct me if I'm wrong but I thought that the GTI LE didn't have a limp (only a overheating long beep from the lanyard). I thought limp mode was only for the DI models. I read something to that effect in my own manual (a 2003). Unless they changed it from 2003 to 2004.

My motor gave away very fast at 133 hours. A few days and it was dead. In between, I did experience a sudden drop in speed and a few minutes later it was dead.

Where you referring to the original post because mine is a DI model

[benjilafouine]

Yes, DI has a limp mode when I read my manual.

Did you check compression?

Lets start simple ......Is there still oil in the oil tank? Is there oil in the bottom of your hull?

 

[fignewton202003]

I have oil in my tank and there is oil in the bottom of my hull
