I have same motor on a beneteau 32.
to read the oil start the engine a few minutes, turn off, unscrew the dipstick, clean it and then put it to read it without screw in it.
Is very dificult to see the oil in the stick, use a white paper, then touch the paper with the stick to read it.
A few month ago my clutch was sliping, you need to change the oil with new HD 30 oil, it use so little, you need to fill it little by little and messure it.
Don't overflow it because it will hot the transmision.
