  1. 903 heat exchanger”radiator” fitting for cap damaged.

    It is cut all most completely off at the surface of the steel tank. Recommendations range from epoxy, silver solder or brazing. Everyone wants tank removed. Fifty year old bolt removals seems like a nightmare of problems. I’m thinking of connecting the fitting to the plate off the boat and then...

  2. Allison transmission oil??

    Have a Hatt 50 Sportdeck with DD 6V92s. I use the Rotella T pure 40W in the engines. Should I be using the same oil in my transmission?

  4. New Here - Prospective 71 Hatteras

    Hello All, After much research I reached this forum as part of my decision making process in possibly purchasing a 1971 Hatteras. I recently sold our 1974 Egg Harbor after several years of trying to keep up with the wood cabin and window issues; the boat had potential but more work than I...

  5. Hand Rail Refinish Question

    So IOLANI is in dire need of handrail refinish. The marina where we keep her moored in the summer is not really conducive to a lot of noise and dust from power tool scrapping /sanding. The marina that has her up on the hard has strict rules which prohibit any sanding or painting unless you use...

  6. Oil Pressure Gauges Only Working in Engine Rooms

    The oil pressure gauges at both our pilot house and flybridge helms only rarely come to life. The ones mounted inside the engine room doors work as expected 100% of the time. Before I go down another rabbit hole, is there any chance that's a well known issue with a common fix? All the other gauges...

  8. Intermittent Bennett Trim Tabs

    I was having some issues with my boat planing when I first got her and narrowed it down to a couple of things including the trim tabs not going down. It seems sometimes they do and sometimes they dont when using the switch at the helm. If I jump the terminals at the pump, down in the lazarette,...

  9. AC drain sump/ Bilge Pump repair???

    I have always had a bad smell in the center ac drain sump box. I decided to replace pump, hose, lever, and clamps and investigate. I found a big glob of failing silicone under the pump and lever.

  14. Cruisair Amerage Draw

    The salon Cruisair unit on my 56 MY has started to draw a lot of amps, albeit only for a split second (like 1/10th of a second). When the compressor kicks on, it will draw anywhere between 60-80 amps and then drop down to normal draw. Other than the amperage spike the unit seems to be working fine....

  17. Hatteras Door Locks

    Not sure this qualifies as a technical question but here we go. My 1976 LRC uses exterior door locks that use a "bit key/skeleton key", with the lock mechanism providing a see through path to the inside. I would like to have locks that limit the breeze and bugs that use these paths. Anyone aware of...
