Today I changed the oil for the first time. (Not the 10-hour change, just my first time changing a boat's oil. I've done plenty of cars and motorcycles before.)
I bought the boat used and it came with plenty of Yamalube and a new filter, which was great! But the filter itself, 69J-13440-04, had a dent in the side. Having had a motorcycle lose all its oil (while parked, thankfully) after taking a piece of gravel to the side of the filter, I decided that I shouldn't use the dented filter. But I also didn't want to wait to order 69J-13440-04 specifically, so I looked for a match online.
Weirdly there are a lot of matches for 69J-13440-00, but hardly any to be found for -04. But I found the K&N HP-1002 was a match for the -00 and it seemed to match the -04 I had in my hand as well. So I went with that! Seemed like a perfect fit - any concerns?

Also, I was only able to extract about 3L of oil. Seems like some others get 3.5L+. Is getting 3L out good enough or should I consider a mid-season change as well?
