  1. Exhaust temp problem

    One side of one of my 8V71TI’s is hotter at the exhaust elbow, than the other side by about 20 degrees at idle. I just did the heat exchanger’s, and intercoolers and today I pulled the elbow and tried Rodding the water passages in the shower head. I can put a garden hose turned on full blast and...

  2. Boaters Diet: Fiber or Copper

    This is a 1972 43' DCFB Hatteras with J&T 6-71N's at 310hp. I ran a short test run out on Lk MI, in preparation for a full run up the lake from White Lake to Cheboygan and my new-to-me dockominium in Duncan Bay Marina. Whoa, my son at the helm noticed (very thankfully) that we had lost oil...

  7. Ultra Sonic Cleaning of coolers

    Can anyone recommend a place in N East Florida that can ultrasonically clean and pressure test my coolers? Got a place up in NJ but would prefer to drop them off and not deal with boxing for shipment. Not interested in Rydlyme or Barnacle Buster.

  8. Question Hardtop replacement options - 1969 TC

    Likely one of many questions after Ian. We got "measured" 202 mph gusts up the bum, getting under the hardtop and blowing it straight off the top. No major damage to the boat structure otherwise. Currently sitting upside down on the dock next to the boat in one piece. Heavy as all get out! If...

  9. thanks, but to who?

    A few years ago, I bought an oil change pump to replace the one in my boat's plumbed-in oil change system. The original was a Reverso impeller pump- not the greatest. Each impeller basically lasted a season- in other words, one oil change. This year, with the Reverso pump finally not working at...

  10. Aft deck windows

    Starting on a post storm project. The sliding windows on the aft deck of my 43DCMY had a couple of cracked windows and some rot in the wood frames. Well, a strong gust from Ian removed 2 of them from the port side. So, I am rebuilding from scratch. I decided to make new sliders out of aluminum...

  11. How often to replace exhaust manifolds?

    My Dd 4-71N engines have a collant-cooled exhaust manifold. No idea how long they've been on there. Does anyone know if these corrode and need regular replacement?

  13. Beating the heat

    I had this sunbrella panel sewed up . It does a good job shading the salon window. It is easy to step past, and I can still see outside. Capt. Rob

  16. Cummins Onan Generator

    I am replacing my original Cummins Onan generator 15Kw that came with the boat 53MY in 1981. The generator is leaking coolant into engine (comes out the exhaust) so believe it may need new head gasket and planning of the head. The unit runs but overheats under load due to this issue. If...

  17. 58’ motoryacht props

    Hi everyone, this is my first post. In February I bought a 1977 58’ motoryacht with 435hp 871s and 2:1 Allison transmissions. Does anyone know the proper propeller for this boat? What’s on her now is one 28x30 and one 27x31. Supposedly they’ve been reconditioned to match each other. I’m having work...

  18. Vertical Wind Turbine?

    I saw that this question was asked in 2010 with no answers, and now I'm also looking for an answer. The question is if anyone has experience or done research on a vertical wind turbine on a Hat. I don't like the typical horizontal wind turbines you see on many sail boats, but it looks to me like...

  20. Anyone removed their Cook-N'-Clean center themselves? Have question.

    Our trusty Cook-N'-Clean center decided that it had cooked one too many turkeys-on turkey day, no less. The oven tripped it's fuse and I now need to extract the Cook part. It's not installed like the manual says, rather Hatteras used hidden screws (which I finally found buried on the 1/2 depth side...
