Yeah, since I live full time by the lake, I often use one or the other Sea-Doo (213 hours on the old one and 50 hours on the new one). I must be doing around 50-60 hours per year. This is a large lake with beautiful beaches and sand bars so it is tempting to go there just about every day in the summer!
Oil filter: you mean replace it? It was replaced when I replaced the engine an 2015.
Fuel strainer: I do that often. I think it is due, will check it today before putting it back in the water.
Jet pump oil: I do it every second year, will be done at the end of this season.
Wear ring: was changed two years ago.
Carbon seal: checked the assembly today, everything is tight and no noticeable gap.
This old ski is clean, you could almost drop your sandwich inside the hull, pick it up and still eat it!
