  1. HVAC controls

    I have a 1987 43' MY and the previous owner replaced the HVAC knob contoller with a residential T-stat and now the reversing valve does not engage. Does anyone know where I can purchase a controller for a cruise air unit? Does anyone have any idea on what might be causing the reversing valve to...

  2. Exhaust Riser Tank mounted directly above DD 871...has anyone replaced???

    Hi Guys, I'm considering a 1972 53MY with 871's and the original exhaust riser "tanks" mounted right over the engines. My broker was kind enough to alert me to the danger of water getting into the engine should the tank "fail". Has anyone had these modified and can you tell me the cost to...

  3. Turning off all batteries with Perko knobs

    I have never done this before but so I wanted to ask the pros for advice. First my boat is bone dry and doesn’t leak anywhere. The bildge pumps are wired directly to a bus bar to the battery power. Should I turn off all breakers for the batteries one at a time or turn the perkos to the off...

  5. Allison Transmissions, where is the oil going?

    My Detroits (471's) have Allison transmissions. The Allison transmissions have, ever since I've owned the boat, consumed oil. I'd say they require my adding about 3-4 ounces every 18 hours or so of running time. No a big deal, but I should would like to know where it's going... The oil...

    Hi Gang, Thanks in advance for all responses! My wife and I previously owned a 56' Hatt (at a different marina) which we had to give up in 2016. We really loved the 56 and are now searching for the largest Hatt we can fit in a 56' slip at a yacht club I joined where dockage is more...

  7. Time For New Batteries

    Marine electrician just left the boat and he thinks our problem is the batteries (and possibly the charger). Kind of what I figured TBH. I know this is opening a whole can of worms, but what's the current thinking on new batteries for these old 32v girls? Our M.O. is to start the generator...

  11. Electrical Panel - Generator Switch Headache

    Among the problems I'm currently dealing with is this thing: The last time I used this generator (about two months ago now), the switch fell off in my hand. I tried everything I could think of to get it back on the mounting post, but it just spins free in either direction. I assumed the...

  12. Proper size batteries?

    I purchased all new 8 volt batteries back in November. I installed them and they worked perfectly until about a month ago. I had my mechanic come over, he is also an electrical contractor for boats, and he tested everything from the starters to the cables to the batteries and charger. The motors...

  15. Morse docking lamps led re-bulb

    If anyone is interested in modifying their old school Morse docking lamps to led, this project took me about 15 minutes per bulb to physically accomplish and about 5 years of searching to find a suitable bulb. The led unit is a Sylvania 4” Rugged Round LED Pod, as they call it. It’s 2100 lumen...

  18. 20 kw ONAN Engine Kick Back on Shut Down

    Scratching my head on this new ONAN gremlin. Whenever I shut it down, the engine kicks backwards just before coming to a stop. Next start up, the belt slips and will not engage the raw water pump due to the impeller blades being bent in the wrong direction. I've tried tightening the belt...

  19. 1970 44 TC engine mounts

  20. Another Access Mystery
