  1. Oil leak at crank pulley retaining bolt

    I took off both crank pulleys some years ago to replace the front crank seals. Not an issue and all went back together fine and dry until now. The crank pulley retaining bolt didn't have any type of gasket under the washer on either engine. Didn't give it a thought then but now I assume the...

  2. What do you wish you knew before you got a davit system?

    Our 54' Hatteras has no davit. I want a dinghy, if for nothing else, to get street cred as I putter down the ICW. We are flexible on time as I don't think it will become a true pain point until next year when we can hit the Bahamas. What do you wish was different about your davit? We have a...

  3. Nameplate for 86 45C

    The Hatteras nameplates on my 86 are pretty corroded and crappy looking. I've tried searching the SAMS site to no avail. Anyone know if replacements are readily available?

  4. Turbo Blankets for sale

    A fellow HATTERAS owner purchased these only to find out after rebuilding the motors they were the wrong size. He paid over 250.00 for each and wants to get 200.00 for each. I’ll add a few photos. For more photos send me a private message and I’ll text them to you. Thanks.

  5. 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...

  7. Wiring/lightng question- 110volt to 12volt AC... is this Hatteras Normal?

    Hey guys, I'm sorry if this has been asked before, but you can't search the forum and after looking thru 10 pages (and getting really distracted) I don't see a post about this. I have a 1981 61' MY model (now 70') and I am trying to swap everything to LED and the craziest thing... I have...

  8. CAT Marine Power Display Repair

  9. 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...

  10. 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...

  11. 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...

  13. 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,...

  14. 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. After vacuuming as much of the solid black water out of the old holes, I am looking to repair. I...

  19. 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....

At the same time I would like to be able to use the new primer pump to polish the fuel and/or transfer fuel in-between the 2 fuel tanks. The new primer pump could also...
