    Here is what I did with the converters on Cat 3116 engines back in 2014.

    Fellas I have a air leak on my air horn. Is there anywhere I should look first.

    You prob have a Kahlenburg horn. They have good service. Find model #, Order a fitting kit for about $30 and replace each of the fittings at the pump and tank. Easy job.
    On my 2006 44DB the model # was P449
    Called them at: (920) 793-4507
    The pump is mounted on the starboard side inside the hollow of the swim platform.

    Only difficult part is crawling over the rudder posts to get back there. If you're a big guy, you may need to outsource this. I'd recommend you cut a 1/2" piece of plywood and lay it on top of the rudders for you to lay on.

    Hopefully your air pump is not located where mine is since mine is in the furthest rear starboard corner of the boat and near impossible to get to unless you are a 5ft 100lb contortionist but that is where the air leak was on mine. I have been tempted to make an access port under the swim ladder cover at the rear.
    By the way my air tank is back there too and I have no way to drain th condensation since I can’t get to it.

    I disagree that the horn pump is that hard to get to. I'm 6' and 190 and not young, and there was plenty of room for me to get back there (your results may vary :)). The key is to put a board over the rudder posts to give yourself something to crawl/lay on. Those rudder posts are very sturdy and can easily hold a couple of hundred pounds.

    Someone should design alternate fittings for those horns, because I think the factory plastic compression fittings are not rugged enough for the marine environment. It seems to me that some sort of screw-on fitting, similar to used on an ice maker would last much longer.

    Kahlenberg sells a kit that does away with the plastic fittings. Likely your leak is around the tank.

    The solenoid is prone to corrosion internally and will eventually slow leak air through the horn. On my boat that solenoid is in the bridge overhead console just under the horn. Disconnect the outlet hose and put your finger over the end with a little dish soap and water solution. Bubbles will tell the story. Mine was corroded internally beyond repair - I replaced with a Nitrous Oxide solenoid I had laying around; works perfectly - something like this https://www.summitracing.com/parts/zex-ns6521
    There is also a fitting in where the roof arch connects to the bridge which can leak. That is where all of the systems are disconnected for OTR transport bridge roof removal.
    The only other leak points are around the pump and accumulator tank.

    I have a leak at that disconnect. My arch was removed for truck transport and the hose was disconnected along with the wiring - It’s been leaking ever since. It’s behind a panel near the U shaped seat backrest on the stbd side. They use a connection that is difficult to assemble. Very frustrating. I’m now looking at alternative methods of joining the two sections

    I also had to replace the solenoid and used this. Also worked perfectly….

    I had a leak also, turned out to be the bottom of the accumulator tank rusted at the seam. I replaced tank with a stainless one.

    Our air hose was leaking at the accumulator tank as well. The Kahlenberg repair kit was easy to use. Picked a cool day and used a roll up exercise mat to lay across the rudders. Not too difficult. It helped to have someone pass the hand tools.

    Has anyone installed an under counter drinking water filter with an above counter water tap in a 420/44 DB? If so, what make/model, where did you install it so it wouldn’t be in the way, happy with it?
    Was thinking I wouldn’t mind doing that for drinking water and coffee maker water instead using the water from boat tank instead of always carrying a bunch of water bottles all the time.

    Thanks

    I got an under the sink Filtrete model 3US-MAX-S01

    for the same exact reason as you mentioned in your post. I lug a bunch of 1 gallon jugs that I fill from our filtered system at home. It is not that difficult but it is just one more thing to do and remember. So far, our tank seems to be OK as far as water quality goes. I did shock it with some chlorine bleach and ran it through the system until we could not smell it.

    So this filter goes into the cold water supply to the faucet.

    Cheers!

    Thanks, I’ll check it out. i was thinking of some sort of RO system since we have such a deep cabinet under the sink and tuck to filters back a little out of the way, if not down below under the galley floor next to the water manifold and water pump, and plumb it to the water tap above counter.

    I was just thinking about the deep cabinet under the sink...yes, it is quite big but you have to access it from an eleven inch wide door opening. That assumes you snap the door off which is quite easy. Easy to see in but hard to get arms and tools in...!!!

    Good point!
    I wonder if there is enough room below in the area next to water manifold for an RO system and then drill and route the hose to feed the counter tap?

    We decided this summer to add a water maker to the boat. We have been hearing that some marinas in the San Juans are restricting water as they are having issues with supply or they have to run an RO system themselves so they are not too generous with water. Canada also has issues and many places have limited water and sometimes it is pretty nasty...if you can get it.

    Somebody here suggested the Sea Water Pro. Please stand up, identify yourself, and take a bow!

    That is the unit we bought. Started out looking at the Rainman. I like the approach that Sea Water Pro takes at the filters, RO membranes and fittings are not proprietary.

    Here and on following posts, I will walk through the install. Here is the seawater intake:

    Strainer and Seacock.jpg

    The boat previously had a watermaker but according to Mark the previous owner, it would have required more money to get it up to snuff than it was worth. So I lucked out as the seacock and strainer were already in place.

    Here is the lift or primer pump. It does not have the blue tube to the primary filters yet. It is backwards in this picture. It was really tough to determine the flow direction. Easy enough to switch it around.
