This is the worst forum i've ever seen. I own another boat and the forum helps fellow owners out. Here, the ADMINISTRATOR suggests to "READ THE MANUAL" .... wow ... REALLY?
Go ahead an bump me from this poor excuse for a forum. Show some pride PWC owners and quit just viewing these things .. help each other out.
You can buy a pump that will suck the oil out through the dip stick insertion point. Check Overtons, West Marine, etc. Any other issues or concerns i'd suggest you find another forum.
