Checking Oil Level on Sea Doo GT-130 (2015).

[zkmat]

Hey Guys,

Upon riding my ski and launching in the water I checked the oil level...Just below the top dip mark on oil dipstick. I then take for a ride, come home, flush and clean and put to bed etc. Check oil level a couple of days later and its exactly halfway between the two dip marks. Why would the oil have dropped this much? Its a brand new ski, no coloured smoke coming out the back and engine running fine etc. No leaks at all from engine or oil pooling in hull etc. I'm starting to think is oil kept somewhere else in the engine, like does it pool away or thrown away from the oil tank where the dipstick is measuring? I've been doing a bit of reading and have found out about a PTO housing can hold oil? Also for accurate readings run engine to normal temp and then rev above 4000rpm, and cut engine to remove any oil from the PTO housing and put it back into the oil tank. Is this the case? I'm a very pedantic rider and I regularly check my oil levels. I can remember prior to my first service it did the same thing, with lowering oil level amount. Has anyone else had this issue or knows what causes it?

Have a new GTI-155 bought last summer. Oil level never changed with a lot of hard riding. Checked the oil regularly. Sorry no answers to the questions but figured I'd chime in on my experience.

It could have been as simple as how the ski was sitting at the time of checking it. On the ramp, in the water, level ground...

One thing you do not want is a 4-tec over-full. It creates pressure in the crank case and looses engine performance...

I have the same experience, and it's about distribution of the oil (unless of course there is something wrong with your engine). The key is to measure the oil in the same spot using the exact same process each time, and compare the levels over time. I usually have to add about a litre of oil every 40 hours or so, but it also depends on how hard we ride.

Right after I got the boat , I found that Home Depot was given out free levels. So l set the level on the engine and crank the lift up and down until the ball fiils the hole. Then I check the oil while the engine oil is warm . Because of the shape of the boat and in some cases the angle of the land that the boat is sitting on , you will never get it right without a level.
