I have spent a couple of days pulling some boat maintenance. The first annoyance was finding that someone had shipped me an improper primary fuel filter. It was the same number but had a letter suffix. It requires a hook up to monitor and will not work with my install (no way to cap it off). So, I set off to see if WM or another Marine store had one (OEM is Raycor). Nope, so I went to a truck supplier that has a large inventory. Not in stock; can order. Fine. Next day, it's in. Not the one I ordered but compatible per the cross reference. Nope. It was just a bit too large for the housing. Back to them to order what I wanted originally. So, the next frustration was the impeller. Over the 25 years I have owned the boat, I had used Yanmar until I received a Johnson in a Yanmar package. Since I have used the Johnson until this site and WM were out, so I cross-referenced the Yanmar and came up with a Jabsco. Two hours trying everything I knew to fit that sucker to no avail. Absolutely could NOT get that thing on the shaft. I gave up and put the old Johnson back in. Took all of 20 minutes. (It was in perfect shape.) I should mention that the access to the pump is a serious PITA. SO, just a word of caution. As equipment ages, references become obsolete, equipment is changed, and spec's are lost. I have run into the same with my 50 year old Jaguar.
