I noticed that it is almost impossible to get the original SeaDoo oil filters without paying an outrageous amount that is unreasonable. The market is now flooded with the chinese ones that all look alike and are partially transparent.
When you look at them the black or silver part you see inside is one end of the paper filament and the other end which has a hole in it is at the end with the larger diameter. Oil is intended to enter on the smaller end and flow towards the larger end which should be placed on the side towards the engine. This way the oil flows to the outside of the paper element and then passes through the paper element to the center and from there it passes through the metal end with the hole in it (larger diameter end) to the oil pump. Putting the oil filter in backwards decreases the total filtering area by probably 50% at least.
My concern is how much resistance to oil flow this creates. I have not had the chance to test with oil but will in a day or two. However using water (which was a higher surface cohesion) I was surprised at how restrictive the filter was and water did not just pour out quickly when filled. Since this is just a gravity fed filter with possibly a small vacuum on the side of the from the oil pump I am wondering if these filters tend to restrict the oil flow since these machines are not like the 4 strokes that have a pressurized filtering system.
