i have a yamaha factory install unit .. after finishing up spare filters i plan on installing a RACOR with a clear bowl ,put it in an easy accessible area to make replacing easier and where you can see the bowl , the yamaha system on my boat is a pita to switch filters .luckily i only change it once a year
I installed what was recommended for my 1999 Johnson 150 Ocean Pro. No problems. Will post some pics of this project. I had to cut a circular hole for where I installed it back near the transom, but used a deck lid for easy access. This kept it hidden and out of the way.
