Through Hull Adventure!

Anybody ever replace a through hull depth transducer with the boat still in the water?! No, really! I have heard of people replacing a seacock with it in the water (in fact, a guy did it on my boat when working on an engine overheating problem). I just hate the thought of a three day trip and a $300 haul out to replace a $75 transducer. I know it's a bad idea but just curious John S. Cal 31 #33, "Sol Survivor" Shell Pt., Fla

Yes, I have!! Adventure is the proper word, too. My speedo fouled and we needed it for dead reckoning. We had heard of others having done such a thing so my wife and I decided to try. Believe me, a LOT of water comes in fast. With pressure. But it was accomplished and we dried out...Then had a pretty good laugh Just have everything preped, one last deep breath and go......--- In Ca… [at] yahoogroups.com, John Stacklyn <stacklynj@e...> wrote: > > Anybody ever replace a through hull depth transducer with the boat still in the water?!

I pulled a speed transducer while underway in the middle of the gulf of Mexico. I yanked it, plugged it, cleaned it and reinstalled it with less than a gallon of water coming in. It's kind of like pulling a band aid, get ready and do it fast! Only difference is you won't sink pulling a band aid! ----- Original Message ----- From: Jim<mailto:ji… [at] yahoo.com> To: Ca… [at] yahoogroups.com<mailto:Ca… [at] yahoogroups.com> Sent: Tuesday, December 06, 2005 12:20 PM Subject: [Cal_Boats] Re: Through Hull Adventure!

I install, remove, and plug my speed impeller every time I sail and am going to leave the boat unsailed for more than a day or two. Otherwise, it gets fouled. My current speedo has a feature that cuts down on the amount of water that comes in when you remove either the impeller or the plug. My previous boat, however, had no such feature. If you have good access, get ready, and move fast, you could do it with only a couple of cups of water coming in.

I haven't done the thru-hull transducer in the water, but have had the excitement of changing out a speedo unit like Jim where I didn't have a plug and was using an old t-shirt to slow the water flow. I also replaced a through hull transducer unit on the hard at the last haul-out and will add what I think that I learned. 1. Have more than two people - it is theoretically a 2 person job, but 3 or 4 is more realistic. 2. Have everything ready. And empty the boat of as much stuff that you don't really want to get wet - just in case. 3. Make sure bilge pump(s) is working and the batteries are fully charged. And if you have shore power as well - make sure the batt charger is working AND that the GFCI is working - don't turn the power on unless you've decided it's really time to run the bilge pump. 4. If the old transducer is really not working or you don't care about it then cut the power/sending cable close to the unit. Otherwise, have the cable coiled and close to the unit in such a manner that the cable can be quickly pulled/pushed/poked through the hole in the hull by one person while another is trying to stem the water flow or is in the position to do so as soon as the cable is clear. 5. Be prepared to have to really "smack" the cable/threaded end of the transducer in order to break the old sealant. 2nd inside person needs to be ready to plug hole with a wood plug and/or old rag/towel to stem water flow. 6. A person in the water needs pull the cable through, if still attached to transducer. He can pass the old transducer to the person on the deck. 7. Person in the water to scrape the exterior of the hole clean of old sealant while person inside is holding the plug in. Person on deck can be the tool handler and communicator with inside people as to what is happening. 8. A person on deck working with "in the water person" can put the sealant/caulk on the unit and pass/feed the cable end to the person in the water for getting it through the hole in the hull. Person inside can pull cable in past rag/towel or carefully past the wood plug. 9. An inside person can thread the transducer cable through the new screw on retaining piece. 10. Person on deck passes new transducer unit that is caulked to person in water - communicates to person(s) inside to be ready. 11. New transducer pushed through hole in hull as the rag/towel/plug is removed. One inside person holds transducer in place. 12. Seal/caulk inside of hull and transducer connection area and thread the retaining piece onto the transducer and tighten into place. Things that I found doing mine that were more effort than I would have expected - breaking the seal on the old caulk, cleaning the old sealant off of the hull. From the earlier "in the water replacement" job - I was amazed at how much water comes in so fast! I hope this helps in your planning/decision.

Sounds like a plan Tom. Only addition I would make is a rubber expansion plug. In the event you end up with a problem or extended work hold. Expansion plugs are a shouldered rubber plug with a washer bolt and nut. Insert from inside or out and tighten the nut. No leak temporary plug.

thanks for all the info from everyone who reponded. very helpful! one last question: how about letting her heal over on a falling tide and doing it then? a better or worse idea? stress on the keel? she's a cal 31 w/ 5' draft but the through hull is probably around 2' below water line.

John, While it might be a fun adventure to replace the thruhull while water is gushing in, have you considered just leaving the old one until next haulout and just glueing the new one to the inside of the hull (with silicon sealant)? Alternative is to epoxy a tube to the inside of the hull and fill it with mineral oil then insert transducer and cap it. Most depth transducers should work through the hull surface assuming there are no air bubbles. This is what I did when I replaced mine and it works fairly...only occasionally loses the reading when healed over though. --- John Stacklyn <st… [at] earthlink.net> wrote: > thanks for all the info from everyone who reponded. > very helpful! > > one last question: how about letting her heal over > on a falling tide and doing it then? a better or > worse idea? stress on the keel? she's a cal 31 w/ 5' > draft but the through hull is probably around 2' > below water line. > Thanks again... > ----- Original Message ----- > From: Jim > To: Ca… [at] yahoogroups.com > Sent: Tuesday, December 06, 2005 12:20 PM > Subject: [Cal_Boats] Re: Through Hull Adventure! > > > Yes, I have!!

I'll do it in the yard when I haul in the spring. We used to haul for a weekend and leave the boat in slings to wet sand the bottom. That would be a good time to swap through hulls.

Hi, In the olden days, Alamitos Bay, we installed several transducers without hauling out. We always took the precautions someone else mentioned and had three people. One person in the water with scuba gear and a plumbers helper, i.e. plunger, the second person in the boat with a drill, one 1/4" bit and a proper sized hole saw, the third person was on the dock with the transducer all gooped and ready to go. The person inside used the 1/4" drill bit to put a hole in the center of where the transducer was to go. The person in scuba gear spotted the bit coming through the hull and put the plunger over the area, assuing he had a good seal. Then the inside person used the hole saw for the transducer. The only water inside is the amount inside the plunger. The inside person places another plunger or a piece of rubber over the hole to keep water out while the scuba guy gets the transducer and jams it in the hole. The inside person allows the transducer to push his hand away, then grabs the transducer and threads the ring nut on it. Now all three have a Sam Adams or so. A fair reward for having saved the cost of a haulout. Tom Vandiver, Cal Cruising 46 & Cal 25, Bayou Chico, FL, already up to 67 degrees, maybe I'll take the Cal 25 for a sail. Do You Yahoo!?

John I certainly wouldn't worry about stress on the keel if you careen her. But I think you'll have to be almost high and dry to do it. If you go that route, make sure that your hull is protected in some way so that it doesn't get scratched. That plunger idea with the diver sounded very creative.

You'd want to be very careful and plan the careen. If possible, find some local old-timers who've done it and know a good spot. You want someplace with a slope to the bottom where the boat can lean "uphill" and expose the side you want to work on. I've read that some areas had careening spots all set up, dredged to shape, and formed with sandbags to make them efficient. Make sure you don't careen in mud. Besides the obvious issue of not being able to work on foot, there's the danger that the boat will be stuck by suction to the bottom when the tide rises. In Richardson Bay (Sausalito), we've had a couple of small boats sunk this way during extreme low tides. Of course, in SF all we have is mud or rocks, so careening (on purpose) isn't too common. bw ----- Original Message ----- From: biggs dave To: Ca… [at] yahoogroups.com Sent: Thursday, December 08, 2005 8:24 AM Subject: Re: [Cal_Boats] One more through hull question John I certainly wouldn't worry about stress on the keel if you careen her.

First, be CERTAIN that it's the transducer, and not the wiring or connectors before you do the job. I agree that if you are going to attempt to replace the transducer with the boat in the water, have a few people handy. Fully charged batteries to run the bilge pump and (in case something does go incredibly wrong), an electric (110v) shore powered pump (like a submersible sump pump) for commercial use. You can rent this from almost any equipment rental company. I also agree that you should remove any cushions or items stored near the transducer (as water will rush in) and have lots of towels handy to dry up cabinets and wooden surfaces should they get drenched. Make sure that the caulking sealant you choose will cure under water. I would be nervous to try something like this. Good luck with the project. Let us know how it goes. Scott S.

Yes Be sure. Check the paddle wheel by spinning it and watching the indicator unit no reading check the wiring to paddle wheel spin the the paddle and view the volt meter in AC mode at the connector to the knot meter. The fouled transducer ? Broken? wire? paddles? If the the transducer test bad did you check about just replacing it with a new one. most MFG's have replacements. Signet used a tranducer that would work with their digital and analog meter. But before you do a in the water job make sure the bore size is the same. I know a diver who has done this work on a new boat it took three people. 1. the diver 2. The guy drilling the hole 3 The pump man extra help. Some Ideas Have a diver ready to place the thru-hull in using 3M5200 will cure under water very strong (Adhesive) boat life will cure but longer time frame. Take all of Scotts advice.

Here is an Idea you can mount the hull sounder in a water box with distilled water the lo freq energy will transmit thru the hull via the water its been done you could try this first.
