    MS Pilot 34 - Hull to Deck Joint Leaks

    Hello All, I know that I have read on here about other owners attempting to solve leaks in their hull to deck joints but darned if I can find the threads. So please forgive my repeating the question. We found last year that we had some significant fresh water intrusion through what we believe...

    MS Pilot 34 - Deck Hardware Access

    Hello All, We are attempting to undertake a project to rebed all of our deck hardware but the yard who is working on our boat indicates that few if any of the nuts and backing plates are accessible because the hardware was mounted to the deck before being lowered onto the hull during...

    Propane Stove Install Help/Suggestions

    As the owner of an MS Pilot 34 which is all-electric and in Maine waters, I would happily exchange my induction electric range for a propane one. Having to run the generator every time I want to make coffee, cook a meal, etc. is annoying, loud, and obtrusive to others at anchor. Further, the...

    Yanmar 370 Oil Pressure

    Hello all, I have a 2004 MS Pilot 43 with a single Yanmar 6LYA-STP 370HP engine. Today I noticed something that concerned me relative to oil pressure and wanted to check with others about their experience. In the past, my memory was that as soon as the engine started the oil pressure went...

    Engine zincs -Yanmar 6LYA-STP

    Oil Cooler Anode Life Hi Don, How often do you find that you have to check/change the oil cooler zinc? More than once per season? I have not checked mine since changing them in late May and the boat now lives in salt water once again. Just wondering if I should look at that sooner rather than...

    Can you tell me what this is?

    Excellent Method! Thanks for this. I changed the oil and filter today on our Pilot 34 and punched a hole in the top of the filter toward the end as you suggested then rotated it half a revolution and punched another hole catching the oil that drained out of the filter in an old plastic pan I...

    Can you tell me what this is?

    When you say the filter drains after punching the hole(s), where does it drain to? Back in the engine? Or all over the absorbent pad? I have been trying to come up with a way to not have a big puddle of black oil under the filter in the "bathtub" which does not have a drain on my Yanmar 370...

    Mainship Pilot 34 - Play/Looseness in Helm

    Hello backinblue, We are in your area transiting Long Island Sound and plan to spend the next two nights (Thursday and Friday) at the Mystic Seaport. Happy to meet with if it suits you and your schedule. I tried to PM you with a more detailed message but it was blocked. Hope you are well! Doug

    Mainship Pilot 34 Lateral Fuel Imbalance

    Problem Found After contorting my rather large frame into the forward starboard corner of the engine compartment, I found the starboard vent line. It seems that the diagram from the boat manual indicates that the port and starboard tanks each vent separately to their own sides. However, at some...

    Mainship Pilot 34 Lateral Fuel Imbalance

    More details Dave, Our Pilot has a single 370hp Yanmar. I believe that the return line goes to the starboard tank.

    Mainship Pilot 34 Lateral Fuel Imbalance

    Yes, a blocked vent is my first thought. Going to investigate that in the daylight tomorrow. Doug

    Mainship Pilot 34 Lateral Fuel Imbalance

    Our 2005 Mainship Rumrunner Pilot 34 has a strange quirk that I can only attribute to uneven fuel consumption from the two tanks. When the tanks are full, the boat sits largely on its lines with no list in either direction. As fuel is consumed, the boat lists increasingly to starboard to a very...

    Mainship Pilot 34 Vibration Problem

    2005 Pilot 34 Experience Just to add to the confusion, I just picked up my (new to me) Mainship Pilot 34 with a single Yanmar 370hp engine on Lake Oneida and am heading east on the Erie Canal as I write this. When I had the boat surveyed last Fall (I could not be present) the surveyor noted...

    2005 Msinship trawler, single 370… issues?

    Hi Don, I will happily post some pics but am 400 miles from the boat for the next six weeks so it will have to wait. That said, I can perhaps explain better in the mean time. I have found a third zinc on the aft end of the fresh water cooler in addition to the two that are side-by-side on the...

    2005 Msinship trawler, single 370… issues?

    Zinc Replacement One additional tidbit based on personal experience; be sure all the pencil zincs are replaced regularly around the engine. I printed a copy of the service manual for the 6LYA-STP off the Yanmar web site in an effort to understand where all the zincs might be hiding (among other...

    Mainship Pilot 34 - Play/Looseness in Helm

    Problem Resolved - Thank You! Thanks to all the shared experience here, I was able to order the Sea Star hydraulic fluid and fill tube using the links provided by other members above. There was definitely an air pocket in the steering pump that quickly bubbled out when I added fluid (and...

    Yanmar 6lya-stp oil dipstick. Which one?

    We have the 6LYA-STP in our 2005 MS Pilot 34 and experience the same discrepancy between measurements on the two dip sticks. When we change the oil and put the correct amount of fresh oil in the engine, the longer of the two dipststicks (port) reads full and the short (starboard) dipstick reads...

    2005 Msinship trawler, single 370… issues?

    MS 34 Pilot 34 Rumrunner Fuel Consumption Attached is a little chart I keep around as a guide to fuel consumption on our 2005 Mainship Pilot 34 Rumrunner II with a single 370HP Yanmar 6YLA-STP engine. I cannot recall the source that I lifted it from so if I am infringing on anyone's copy rights...

    Mainship Pilot 34 - Play/Looseness in Helm

    Thank you for this. I strongly suspect that there is air trapped in the steering pump as I could find no play in the linkages at the rudder post/cylinder. The wheel itself was also firmly attached. I have procured the necessary fluid and fill hose and will work on this when I get out to the boat...

    Thank you, Rob! We will absolutely endeavor to reach out on our voyage. My wife and I both have spent time in that vicinity at various points in our lives. Lovely area!

    Mainship Pilot 34 - Play/Looseness in Helm

    Thank you, Backinblue, I will absolutely keep that invitation in mind! We plan to take the southern route due to constraints and requirements of elder parental care and other related responsibilities and it will be much easier to stop along the way and return home if necessary going by way of...

    Mainship Pilot 34 - Play/Looseness in Helm

    Thank you all very much, that is exactly what I needed! I have ordered the hydraulic fluid, filler and bleed tubes and will tackle that little project when we return to the boat in the coming weeks. Our Pilot 34 was purchased last Fall and is in storage on Oneida Lake for the winter. We plan...

    Mainship Pilot 34 - Play/Looseness in Helm

    Darn Good Question Comodave, that is a darn good question and I am embarrassed to say that I do not know and cannot readily find out at the moment as I am 500 miles away from the boat for the time being.

    Mainship Pilot 34 - Play/Looseness in Helm

    We have a new to us 2005 Mainship Pilot 34 Rumrunner II and noticed during sea trials that there was some play in the helm of about 1/4 turn or so before you feel any back pressure and then the helm begins to respond. In essence, you can turn the wheel freely back and forth for at least a...

    Mainship 34 Pilot - Anchor Suggestions

    Thank you all for the quick and helpful replies. I think we have zeroed in on the Rocna Vulcan 15Kg (33 lb.) anchor because it seems to fit the bow pulpit well, has a short enough shank to fit between the bow roller and windlass (including swivel fitting), and is fairly versatile in terms of...
