On outboard models the engine went in there and on inboard model it was considered a "Wet Locker".

Even with the drain, you should not have any water coming from that locker into your boat. If you do the bulkhead is cracked.

Is the old engine room dry?

Re: Possible Leaks? Water Getting Into Bilge

there is a small amount of water below the inboard shaft. boat was originally and inboard boat, but the motor was removed. however they left the shaft coming through the boat. i cant find it dripping from anywhere, it just collects in the bilge while underway. i'll trty to empty the bilge completely and dust it the keep an eye on it

Re: Possible Leaks? Water Getting Into Bilge

I like that dusting idea. I have a little water coming in. A few cups. can't figure out where with it being so little . The powder should give me direction to look.

Is there a chain-pipe on your bow and, if so, were you taking water over the bow during your transit? On our prior boat, a 1976 Cal 2-29, we had a chain-pipe that led to a small chain locker forward of the V-berth. Unless I remembered to block the pipe with a split tennis ball before we went to sea, if we took water over the bow it would make its way into the chain locker and from there to the bilge. It drove me crazy until I figured out where it was getting in--totally by accident.

Also, what's holding the old prop-shaft in place and how far does it extend past the packing gland? If it's moving up and down while you're underway, it could be admitting more water than you suspect or might be evident with the yacht still in the water. I'd tighten that puppy down very snugly considering the shaft doesn't need to turn at all, eh?

Re: Possible Leaks? Water Getting Into Bilge

We had dry boat at the dock with serious water gain while motoring. Turned out it was the siphon breaker at the mixing elbow. Steady stream of water was exiting over the top vent hose from the siphon breaker and putting 250 gallons of water in over about 6 hours of motoring. Fixed it with vice grips.

On the same trip, the tie-rods on the main strainer brioke. They were old. I used a 3-rope tournequette to hold it together. I don't know why I chose that time to inspect the engine room but water was pouring out of the strainer.

If it is a problem that only happens under way, try shutting off and valving out all systems. add them back one at a time and find the guilty party. If it is your keel bolts you can only plan to drop athe keel and re-bed it.

Our boat is old enough that one other issue cropped up. It sat unused and in the water for about four years. I think this contributed to the metal on the shaft at the stuffing box to corrode. The packing doesn't seal well now so the shaft is in the shop for a plasma re-build of the damaged areas.

Re: Possible Leaks? Water Getting Into Bilge

The good news is that the leak is coming from the rudder post. I used gymnastics chalk to figure out where the leak was originating from.

Now for the hard part. On a 1977 c27, does it have a stuffing box or bearing set up? Am I correct in assuming the boat has to be hauled out in order to make the repair? While I am at it I might as well replace the through hull fittings, if it does require a haul out.

Re: Possible Leaks? Water Getting Into Bilge

If, as your previously noted, it only leaks at sea then the top of the rudder is probably above water at rest. I don't know your boat but our Camper-Nicholson has a 3" stock with a plastic bushing. The post is sealed in the lazerette with a stuffing box and there is a grease reservoir with a screw pump to lubricate it. You may need to disassemble steering parts to get at it. If your top bushing(s) are bad you can get replacements for IGUS for way less than in a marine shop. I paid 7 bucks for mine. Ours was totally removed to re-build the rudder.

Make sure you know what holds your rudder in the boat or you might be diving on it. There is a threaded hole on top of our post and a hole in the deck for the emergency tiller. This makes a nice place for a screw eye and block and tackle to the mizzen boom.

Re: Possible Leaks? Water Getting Into Bilge

Unless the stuffing box is hidden by the tiller head, I don't see how it could have one. I don't know if I am using the wrong words or phrases to seach, but I'm not having much luck finding good information on my problem. I'm shooting for a haul out over Christmas break if it does require one.

I'll try to grab some pictures tonight. Maybe I'll see something incredibly obvious that I had previously overlooked.

Thanks in advance,
Jason

Re: Possible Leaks? Water Getting Into Bilge

I'm uploading a couple of pictures of the rudder post, where the leak was originating from, and the tiller head. If anyone knows what is involved in fixing it, or if my boat is a stuffing box type set up or a bearing/bushing set up, I would appreciate it.

Thank you for all the help so far.
Jason

Re: Possible Leaks? Water Getting Into Bilge

So, have you positively identified the leak point? Is it at the top of the fiberglass structure where the shaft is exposed? In this design the shaft exit point would be above water so leaking might occur but not at a high rate. It could be greater if the bearing within the structure is worn. Is your rudder cantalevered from this bearing (spade type) or is there a skeg & lower bearing? If it is a spade, can you wiggle the rudder within the bearing? If you need new bearings you will probably find an exact geometric replacement at IGUS igus® e-chains®, chainflex® cables, iglidur® bearings, igubal® bearings, drylin® linear motion Mine was incredibly cheap. You can also choose a polymer that will out-live the original for a modest increase in cost. I like NYLATRON as a great engineering plastic. Its very strong and is filled with its own lubricants. Call and ask for assistance if you have trouble choosing.

If your leak is in the fiberglass structure you will need to re-build it. Also plan to re-new the bearing(s) if you pull the rudder.

Both situations will likely need out of water attention.

From the looks of the photos it appears that the fibregalss tube for the shaft stops short of the underside of the cockpit floor. If this was designed like that it is damn poor engineering from my perspective.
