Jabsco Manual Pump Assembly f/29090-Series

Must needed part for any boat worth the cost.

This item is great if you have an older Jabsco MSD (head) and cant figure out which rebuild kit to choose. It installs quickly and easily, though none of the paperwork in the box tells you how. (It is all about new head installation.) Go to their website and watch the videos. It DOES come with a joker valve (one review said it does not), but for some reason, only one mounting screw. ( Not sure why one... 4 are needed, but being stainless going into plastic, your 4 old ones will work fine.) Big surprise (not) - this part is $30 higher at your local boat parts store... Job not even as messy as I feared. I made sure the MSD was flushed with clean (lake) water, and darn sure holding tank was pumped out. Maybe 1/2 cup of water came out of supply hoses. Not sure these Jabsco heads ever work great, but if you have to deal with one, this is a fairly painless way to go about it. Now my head is the latest model!

New improved version of this part. Can unscrew pump handle.

It took me about 1 hour to replace it, not the best hour in my live as space is very very tight and, well, you know. But I got it in and it works perfectly. I was very happy to see it fits perfectly in my 1990 original head.

Simple replacement for the original equipment on my boat, works great.

The new backflow gasket is going to solve a few issues. But the outlet fitting is a different angle so you may (I did) have to take the old one off and swap them. If I ever change the whole thing out I would not go with Jabsco.

Works like brand new...wait a minute, it is new. This is my spare but an identical one works better than the one that came with the head when it was new.

Love it. Easy to install. Works great. Got the replacement parts for the one we took off and now we have a backup.

Came exactly as stated and 2 days before I expected it to arrive. Item was brand new in abox complete with instructions. I installed it with minimal problems. I got this item at a fair price. Will use this vendor again.
