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. Cheers Alan Elyse SM437

Hi Kent, We have the same. Identical including the tread on top. Danny SM 299 Ocean Pearl

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

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

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

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

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

Hi I have the wrong antifreeze filler cap on my Volvo Penta TMD 22-A (for the last 5 years). The correct Volvo part number is 861610, but I cannot get that in St. Lucia. I can buy a compatible one

Hi Paul. Please let us know how it turns out. That is a good price. We will be down that way at the end of the season. Best regards # Chuck Joy #388

Thanks Arno. However, I now have a solution: Driftwood in Clarke Court, Grenada, are doing it for USD480. Cheers, Paul S/Y Ya Fohi - Amel 54 #98

When we crossed the Atlantic we ran the genset four hours a day and it was always rolling. Did not experience any problems. Cheers, Paul S/Y Ya Fohi - Amel 54 #98

Thank you for all your replies. My plan is to make sure I know what I have and what I need. A photo of the top of the mizzen is attached, this shows what is labelled as 1. Emergency VHF on top, 2.

Mark, I have an emergency aerial just in case I lose both masts. The main mast carries the VHF and the Mizzen the AIS. These are interchangeable with either the radio or the transponder. Suggest

Thanks Scott/Ryan/JP. Scort, I had seen your post on the bend radius of LMR-400 and why you chose RG8X but thought you had them backwards (I’m sort of dyslexic myself so let it slide). You are

Last season, the Aurora pattern Corian on the dishwasher lid broke. I've found someone who can make a replacement. I have the dimensions (43.7cm square) with screw holes centered 3.3cm from each

I haven’t used the Raymarine system with AIS but I believe that your AIS already has all the information to show the details on the targets but keeps them hidden to reduce clutter. AIS systems use

Brent - Fantastic information! The distinction between an AIS antenna and a VHF antenna is subtle but important and something I didn't know. One thing I will add is that I went for RG-8X. The reason
