Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
Hi Danny, So do we have a flap valve somewhere in the system? I thought it was supposed to be at the muffler. Do we have one at the exhaust exit thru-hull? If not, should we? I have been aware of the fact that water can backflow into the engine on a port tack, and do run the engine and generator a couple times a day while at sea and have had no problems so far.

Re: Replacement Corian for SM2K dishwasher lid
Drew Gaffney
Kent, Thank you so much! This is perfect. I really appreciate your help. You must have made A's in geometry... If anyone needs to replace this cover or the lid to the portside galley counter, let me know. The Aurora Corian seems to be readily available. Hope you have a good sail to the Caribbean. Best wishes, Drew SV Revelation SM2K-390

Re: Batteries
Thank you Gary for your reply. I hope the marina faired well following the earthquake. It will take some time for the mainlanders to get back to life as usual. We decided to go with DC batteries out of Miami. They quoted $2,150 (10 batteries) to St.Maarten through Tropical shipping. We can squeeze a little more life out of these. Can't believe they can ship so cheaply. We will be in Puerto Del Ray marina 1/27 for a few days. I'd like to meet if your there. Best regards, Chuck

Chuck:
Sorry not to respond earlier. Just got a chance to look at messages. Earthquake took out power for a couple of days and wifi just dumped about 200 messages onto my phone. I purchased my Trojan SCS 225 Group 30H batteries from Battery Giant, 1 Calle Acuarela, Suit 102, Guaynabo PR 00969 ( a few miles south of downtown San Juan), Javier (787) 509-0109, main (939) 205-4444. He had to special order them (not stocked) and it took about three weeks for them to come in. I just timed it so they were there when I arrived back from the US. $240 each total including the 11.5% tax on everything here in PR. You will need a car to pick them up. Perhaps they would deliver, don't know as I didn't enquire. It is about a 15 minute drive from the San Juan Airport to Battery Giant, south of the city. I just got them with the rental car upon arriving in San Juan and headed to Puerto Del Rey. Let us all know if you find something better. Gary S.

Re: Recommentation for Sharki second autopilot
Dear all,
thank you for all the information shared about the second autopilot topic. As I have learned from Graham, obviously the newer Sharki models do have a longer mizzen boom and the interference with a wind vane seems then to be a problem. I think I will concentrate on installing a second drive mounted directly to the rudder stock in the aft cabin and probably will add a second course computer, as my old Autohelm 6000 system does allow a connect to the Hydra 330 wind data. Regards, Volker Sharki#176

Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
Jamie Wendell
Having experienced my D3-110 failure firsthand, my theory was that the water infiltration into the cylinders was a gradual thing and was likely the result of excessive back pressure through the exhaust. I cannot believe that the flapper would have let a lot of water into the muffler while sailing or motoring, given the high loop above the muffler. If the engine were "getting weak" so to speak or there were any sort of water buildup at the muffler, I have to assume that my failure was the result of water sloshing back up into the engine upstream of the muffler. There is a valve at the bottom of the muffler, and I now periodically drain it just to be sure.
My theory about too much back pressure is also the reason I increased the size of the hose between the muffler and the flap, and also why I significantly shortened the hose vs. the original long loop. Certainly, Amel's recommendation to run the engine routinely is a good one regardless of the configuration. I am now a happy camper with my new D3-150. Jamie Phantom A54

Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage

Nick,
toggle quoted messageShow quoted text
In 3 years of sailing I have checked my muffler a few times after heavy weather to see if it had excess water in it and so far the level has been about the same, filling the bottom 30% of the can. The exhaust hose on my boat loops all of the way up to the bottom of the deck so is pretty high above the waterline but does not have a check valve/flap in the system. I have often wondered if it might be possible to install a water level sensor of some sort inside of what serves as the water lift muffler on my boat activate an alarm? Has anyone else tried this? Perhaps that could also be a possibility on your A54? Draining the muffler certainly would be effective so long as one remembered to do it! Once the water is removed you of course would then get exhaust into the boat if the drain port was left open so something to consider. I agree an interesting thread. James Alton SV Sueno Maramu #220

Couldn’t that also create the opportunity for Carbon Monoxide to collect in the engine room? (And potentially backflip into the cabin through the (usually dry) drains from the showers and lockers (assuming the sinks all have traps).

Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
On the 54 the exhaust out from the Vetus muffler is a large rubber hose that rises up to near the level of the cockpit floor, before flowing down to the hull skin fitting. In my opinion this is a good installation and unlikely to allow water to be forced into the engine especially considering the additional flap that will prevent waves from being forced in the exhaust line. I believe that so long as the boat is actually sailing there will be no problem as the water will be sucked out of the pipework from the flow of water along the hull. This is due to the Bernoulli Principle, (a bit like the Ventouri effect) which is why a self bailing slot in the bottom of a sailing dinghy draws the water out whilst sailing but when stationary lets it in. I can see that whilst hove to and more or less stationary there could indeed be a situation whereby water works its way into the muffler and then gradually fills up the exhaust outlet between the engine and the muffler. This is the one time when we really do not want to be worried about such a situation. So in conclusion we need to be either mindful of this potential situation and run the engine or come up with something else. I like Leslie’s suggestion of running a hose from the muffler drain point to the bilge. This would drain any water that accumulates in the muffler. It would be easy to install and one could test it and see just how much comes in….does anyone see a problem with this idea? Nick AML 54-019 Ashore Kilada Greece

The flap valve is in the exhaust outlet fitting /// you can see it if you swim around the port side, or when you're hauled out.

Hello Kent, I have an identical SS mixing box. Last year I rebuilt the unit and found NO flap valve inside. However, I do not understand why everyone is intent on modifying an effective system (running the engine 1 or 2 times par day) by adding complication to the system.... Kind regards everyone Jean-Pierre, Eleuthera, SM 007, Opua, NZ

Hello Scott, This same suggestion is written in the SM’s owner’s manual. Another cruiser, marine engineer, seized his engine while on passage Tonga to N.Minerva island. Luckily, we freed the engine and with the extra oil carried on my old girl, managed to get the engine working correctly and after informing him of the Amel procedure, he decided to run his engine every day for 30 minutes. It is preventive in nature Jean-Pierre Germain, SY Eleuthera, SM 007, Opua, NZ

Yep, I ran the engine quite extensively on my "maiden voyage" to Annapolis. Ran fine for the trip, but after a week of sitting at the dock, the engine would not start. The rest is history.
And yes, I worked the outlet to prevent ANY possible ingress (both internal and external). No problems since and I left the generator as original. With the water/gas separator on the genset I have never had an issue. Safe travels and enjoy New Zealand. Stay away from Australia for now though. Jamie

Re: Amel's suggestion to run the Volvo D3-110 (A54) daily while on passage
Kristy (SM243) has a stainless steel mixing "box" instead of a Vetus muffler. Pic attached. Is there a flap valve here as well? If not, can one be added to the exhaust hose? If that's a bad idea, should I be getting a muffler? Thanks, Kent and Iris Palm Beach FL heading to Bahamas and S with the next weather window.

Hi Drew, Here are some pics of how I measured. It appears to be a 30mm radius when I use the calipers.

Hey Jamie, good to hear from you. Did you run the engine on your maiden passage from the Caribbean to the Chesapeake? Not assigning blame, just curious.
Did you decide to rework the exhaust to prevent future water ingress problems with the muffler system? We are in Colombia now and next (Northern) winter we'll be in New Zealand, assuming the boat agrees with our plans. -- Scott 2007 A54 #69 SV Tengah http://www.svtengah.com
