I was looking to replace my bilge pump hose on my 1987 O'Day 272LE. As I was inspecting and measuring, I noticed a few odd things. The Rule 360 has a 3/4" standard bilge hose attached to it, but that hose was then attached to a wider hose under the starboard quarter berth. This wider hose was attached to the through-hull fitting. It also looks like the smaller hose continued the run inside the larger hose. No problem, I wanted to change the hose anyway, and eliminate anothger jury-rigged mess from the previous owner. I measured the through-hull fitting (inside the starboard lazarette) to be 1" diameter. However, bilge pumps seem to come in 3/4" or 1 1/8". It is possible that I measured the through-hull too hastily and in the dark. I believe this is original to the boat, according to my manual. I can easily get an adapter fitting to go from 1 1/8" to 1". But I was searching through the forum, and I noticed that everyone was mentioning going high on the through-hull. My through-hull is quite low, not much higher than the boot stripe. I have never had the boat healed too far for very long, but if I did, I imagine I would have water come in. Has anyone had this happen? Before I thought of this potential problem, I was asking myself why the bilge pump did not travel to the port side, using the same through-hull as under the vanity. It would be so much shorter - it almost seems too easy. Again, the through-hull is quite low, and obviously I would have to deal with the vanity. But we hardly ever use it anyway. We are talking about a run of no more than 3', as opposed to about 16'. I was planning on upgrading from the standars white corrugated hose regardless. A companion issue to all of this is what got me started in the first place. As you all know, there is no escape route for the liquid that accumulates under the inboard motor. The best method I have found is using a turkey baster to suck it out. I have a manual pump in the cockpit on the starboard side. It is the same as the one in the V-berth for the holding tank. The starboard manual pump was not connected to anything. The surveyor recommended connecting a hose to the bilge, and tapping in to the same through-hull I mentioned earlier. Could I attach a hose to this pump and run it to that infamous spot under the motor? It would be much more civilized than using the turkey baster. Not being an engineer, would there be an issue with the diameters? I believe this manual pump calls for 1 1/2" hose, but I have to take a closer look. Sorry for this long-winded essay, but sometimes more info is better than less! Thanks, Robert

pumps
there are one way valves that fit in the hose to stop backwash, and before going thru the thru hull, you should put a loop that reaches farther up the inside hull and back down, if you are worried. but the oneway valves should handle that problem, to stop water from backing up, just like the loop in a head inst. consider using smooth lined hose for greater pumping ability/gph out of the pump.

bilge pump routing
re; your connecting to the sink hose thru hull. not a good idea. when healed the fitting may be under water. the best place is the stern above the waterline. also install a check valve to insure that you can't get a possible back siphon into the bilge,possibly sinking your boat.not a good idea either!!!!!!!!. don't connect a bilge pump to the pan under the engine. the pan is there to keep oil,fuel etc from getting into your bilge. i put oil soak pillows under engine to soak up any oil. can be purchased at marina's or ww grainger.

My method...
My 272LE only had a manual bilge pump when I bought it. Instead of doing up another thru-hull, I cut the pick-up foot off of the existing manual bilge pump line and added an automatic bilge pump. The electric bilge pump pushed water through the manual pump very nicely and the manual pump worked just as well as it always had. No drilling, cutting, or running hose and definitely no check valves to malfunction (and the DO malfunction). Cheers, Bob

Robert, I have the same set up Bob Todd describes in my '88 272LE . Works just fine! Hello to Bob T. and happy sailing, Brian R Clare

Hi Brian!
Splashed my boat this past Monday. Just straightening out a few things and then the season begins. How's by you? Good to see you're still haunting this forum. Alot of terrific info here. How's the boat? Any major projects for this year? Seems to me that you should be all done with anything big. Hope all is well with you. Cheers, Bob
