2000 Seadoo Speedster Oil Sensor Problems

[tgsteinhart1s]

Hello All,

I have a 2000 Sea-Doo Speedster over the 4th of July weekend my oil light came on, and sure enough I was out of oil. I went ahead and filled it with the proper oil ( I forgot the brand but it was DFI). Needless to say the header is totally full (pump is working) and the boat runs great. However, whenever I begin to hit chop, the light and buzzer came off again. Once I start idling it will shut off. I have taken off the sensor and cleaned it to make sure that nothing was holding the float, and still having the same issue. The sensor was working fine until I ran out of oil, so I'm not thinking that its the issue. Anyone have any ideas on what this could be?

This year... I've see a few of the switches go bad.


BUT... before we blame the switch... what engine do you have?

 

[tgsteinhart1s]

It has the Mercury 240EFI

It has the Mercury 240EFI

OK... is the top flywheel cover round, and only coving the flywheel... or is it large, and coving most of the top of the engine?

 

[tgsteinhart1s]

Just the flywheel

 

[Dr Honda]

OK... it's a first gen 240 engine.

You didn't need DFI oil... but it should be fine, as long as it was listed as TC-w3 certified.

The switch/sender in those engines don't normally have issues. But I would simply take the cap off again... and make sure the wires aren't twisted too tight... and the bullet connectors are clean and pushed in tight.


Also... the buzzer, and light are "Generic". I know that the light has an oil can next to it... but the icon is wrong. (Seadoo did that) From Mercury... it should have been a bell. The light will come on with any engine fault. SO... if it came on... and was steady... that could be an over heat situation. If that's the case... try to give the engine a good flush.


If it was beeping (on off) then it could be water in the main fuel filter. You may want to drain that just to check.

Is the fuel filter easy to find? I'm thinking it may be something with the sensor wires because it only goes off when I hit waves

 

[Dr Honda]

It's the big spin on filter, on the starboard side of the engine. There is a sensor on the bottom, with a wire attached.

Either replace the filter (if it's been a while) or take the sender out of the bottom, and drain it.

 

[tgsteinhart1s]

Thanks. I will try this next time im on the water

 

[tgsteinhart1s]

Thanks. I will try this next time I'm on the water. Would it be a bad idea to drive the boat when the light comes on? The engine runs great still. Just wondering if I should try to fix this before I take the boat to the lake again.

 

[Dr Honda]

NO NOT run the boat with the light on. It trips for some reason... and if it's a real reason... you could kill the engine.

 

[tgsteinhart1s]

Since it only goes off whenever I hit waves, is there any other way for me to determine that I fixed the problem besides driving it? Definitely don't want this to turn into something expensive.

 

[Dr Honda]

Unfortunately... when it's an intermittent issue... you may have to take it out to check it. But, don't go to the lake with fam/friends and decide to ignore it. I can't tell you how many skis and boats I've owned over the years... and I take them to the water... and load them back on the trailer 5 min later. (when fixing multiple things)

 

[tgsteinhart1s]

Little embarrassed to say this but having trouble finding the fuel filter. Anything more specific I can look for?

 

[Dr Honda]

it's a big spin on filter on the starboard side of the engine.

 

[tgsteinhart1s]

Thanks, I will be able to find. Does the header tank need to be 100% full. Its about 80% full. My reserve tank has plenty of oil. Just wasnt sure if it not be all the way full could trigger the buzzer.

 

[Dr Honda]

If there some air on the top... it should be OK. BUT... I'm not sure what level the buzzer will come on.

Regardless... if the system is working... it should stay full.


I guess if it was my boat, I would top off the header tank, just to make sure it was properly feeding from the main tank. AND... to make sure the injection didn't get any air in it.
