Personally having been a diesel mechanic most of my life in most cases not a lot of difference in most filters but one thing you need to find out. Most outboard filters have a no drain check valve built into filter because of the way they mount. Find out if that Fran has the check valve. If not don’t use it. Lots of other good filters out there. Another thing you could do if interested is sacrifice cheap Fram cut can open and remove element. Then remove the old zuki filter and unroll it. Get a good comparison on amount of filtration between the 2. I have used NAPA gold filters on my Yamaha with no issues.
