  2. Generator sound shield

    I have a Phazor gen set on the boat and it has fire-resistant fabric type sound shield. It is a chronic pain in the hips when I need to work on the Gen set. The sides and top are velcroed to each other and supported by a framework of tubes that come apart when you don't expect it and is difficult...

  5. Windows

    Do you guys with either 53 , 56 or 58 Motor Yachts that have framed aft deck side windows have glass or plexiglass in them? If you have glass is it 1/4 inch laminated or something else. I now have plexiglass but would rather have real glass if it would work, but not sure if those panels are to big...

  6. Twin Disc MG506 erratic oil pressure

    I've got 6-71Ns with Twin Disc MG506 gears. The SB gear has started to have swings in oil pressure that it hasn't previously had. It usually runs at 360psi according to my helm gauge, which is mechanical. I changed the oil, replaced the screen, and replaced the screen gasket. That didn't help...

  7. External strainer for genset

    Got this baby sendure strainer NOS. Love these things. Am contemplating putting it on genset. I’ve found they block enough light that crustaceans don’t grow inside. In your opinion, does this constitute enough of a scoop to cause the raw water circuit to fill underway? Is the raw water...

    Hi all, I'm considering a well maintained 48 Yachtfish that is currently on the market. I'm hoping there are some 48YF owners that can chime in on a few questions. The engine room is quite crowded. With the DD 8-71Ns, 17kw Onan, batteries, air conditioning, Naiad hydraulics and more jammed...

    I am a Naval Architect who got bored and made a model of my 1968 50' Motoryacht. I'm going to use my 3D printer to make a 50:1 scale model to put in the saloon.

  11. Galleymaid windlass- not putting down.

    Good morning. I have a Galleymaid windlass (220V- original 1989 model). I rebuilt windlass gearbox 10 years ago and has all worked well. I use the down function sparingly, as this is a known cause of gearbox failure. This weekend, it would not operate in the down function-No motor - nothing. I...

    Gentlemen (and the odd Lady): I keep burning up the keyboard with questions as I embark on the refit project for the 1988 67 (enclosed platform making it 70) CMY. My top of mind quandary has me going back and forth between Gyro or Fins. (The SeaBrace fins are loooong dead.) 9sq ft seems...

  15. New (?) USCG fire extinguisher rules

    That’s a new one to me… in addition to the previous requirements, it turns out that boats over 65’ now need to carry extra fire extinguishers in the engine room based on engine horsepower even when a fixed system is installed. This came up during the annual system inspection on the 110’ I run;...

  17. DD fresh water pump

    Is it possible, or advisable, to swap the seal in the water pump in place on 871? Got a weep out the hole under pressure, no weep without pressure but either way the writing is on the wall. If the pump can remain in place it will be a whole lot less work and no worries about gear lash setting.

  18. WOT 6V92’s realistic cruising speed ‘81 43c

    Our 1981 43’ convertible w/hardtop is powered with twin turboed 6V92’s and I am wondering what the WOT RPM should be under load. Also I run about 15kts with 7/8 full of fuel at 1880-1900 RPM’s depending on sea conditions. Are those figures I should expect? She is a heavy old girl and we love her....

  20. SIMRAD Auto Pilot Novice Question

    Ok so my boat has an older model SIMRAD auto pilot on board. I have never had a need to use it and don't foresee a need to use it anytime soon but was curious to know if it's in operating condition. I powered up the control but didn't realize it was on because the display is toast and very...
