My primary pump (read not the big one) is a Whale diaphragm pump which lives in the head. There is a Y valve which when switched pumps out the sump for the shower, which has never been used. This pumps out the side about a third of the way back from the bow. I just replaced the hose to the pump from the bilge, ¾ X 10 feet, and when it pumps with this diaphragm pump, it doesnt run back, which is a good feature. Along with being able to pump crap without screwing up the pump.

My pump works, and there has been a check valve put in by PO, but the long hose simply holds the water and the bilge pump can't do its job... thanks Richard Richard N.

Install one set screw snugly to hold the flange in position, use a small drill to make the detent in the other hole. Then install that set screw tightly with threadlocker. Remove the first screw and make a detent for it. Dennis C.

But I have two maintanence issues. 1. Automatic Bilge Switch problems Alera is factory wired for a manual switch and then a hot lead to the bilge to use with the switch. There was no auto switch on her when we got her a few years ago and since we keep her in the water all year, I needed to install one. I like state of the art electronics so I went with the fully electronic Ultima Bilge Pump Switch. Instead of mounting the switch to a 1/4" piece of plywood as instructed, I mounted it to the floor of the Bilge directly. which may be contributing to the bad cycling problem. The first one I installed started coming on and refusing to shut down until we cycled the manual switch. This week end it was so bad I just pulled the fuse. This weirdness had started when we were on our summer cruise. So, I had a replacement switch on board. I replaced the switch, but may have screwed the wiring up. It ran, but did not shut down. So, as I have been doing before when it would not shut down, I cycled the manual switch and it shut down...but from the way it shut down, I suspect I fried something because the switch is not working at all now. I checked the breaker panel and all's well there. The in line fuse I installed with the switch is fine as well. The manual switch is still functional...thank god! (see 2 below!) 2 Dripping dripless bearing In March when I had her bottom painted I had the yard (Seaview West in Seattle) install a brand new dripless bearing. As a result of the bilge switch issue I decided to check the bilge on the 2 hour run back yesterday. The bilge was substantially filled. I traced the ingress to the dripless bearing which was spewing water everywhere. Not enough to outpace the electric bilge pump or require whalegusher intervention. After we docked I checked and the rotor was loose enough for me to turn it on the shaft. I am getting the documentation from the yard to make sure I get the right parts, but as I understand it, I should not just tighten the set screws, but replace them to be sure they bite, then use a 2nd set crew and lock tight to lock them in place. Any thoughts on these electronic switches, alternatives, dripless bearing maintenance or anything else?
