  1. Transmission oil

    I have a 1979, 53 foot MY and I have changed all the oils and filters. Can anyone tell me how much oil should the transmission hold? I have 8V71 TI’s with Allison transmissions.

  4. Cummins 785 and Cummins 903 compatibility

    Hiya Sam’s group! I have a 1970 53 MY with the Cummins 785s / V-370s. They are running ok, but major oil leaks. Stb side is blowing some smoke. I’m contemplating a repower. I believe the Cummins 903 is a very similar block and heads. Curious if anyone knows whether the 903s would be a...

  5. Anyone know what the purpose of these 6' long cabinets might be?

    There are 2 of these near the aft door. 6' long, 3' high, about 4" wide. Has a latching door on each. I don't really want them but don't want to get rid of something that has a specific purpose. Any ideas of why these are on my boat?

  7. 53 My with Pipe Welders davit, make it taller?

    Last year I went through the exercise of building a lifting bar to lift a 13' Whaler on to the top deck. I unfortunately flubbed my engineering bending moment calculations and it bent on me LOL. (The issue was a lack of lift height using lifting straps, need about 2' more lift roughly.) So...

  9. Bulkhead Construction

    So a sort of tangential issue to my boarding lights problem has come up. Can someone give me an idea of how the bulkheads - specifically in the salon area - are constructed? I'm likely going to need to fish new wires through the walls and I can't wrap my head around how they're put together. ...

    Yesterday, we were out on the hook for the 1st time in a few months (a number of repairs and upgrades being done) and had an issue with my Victron Multiplus not charging properly. About 3 weeks ago, I had updated the Firmware on the Cerbo, Multiplus and BVM. Didn't notice any problems as the...

    We have a lot of lights out on our boat. I want to replace everything with LED. Have found a few good posts about the process, but does anyone know of a list of bulbs specific to this boat? I don't want to pull all the bulbs, write down the model #s, then put them back in, then order, then...

  14. Floscan 236C senders, can they be opened and repaired?

    Has anyone successfully dis-assembled their Floscan senders to diagnose and/or repair them? Are they gear drive or optical? My starboard engine is reading only 2.4v on both fwd and return senders and I think the mechanism inside may be "gummed up" or sticking. Other engine, the senders show...

    Hello all, One of my first experiences on our new boat was with the giant octopus 50 amp shore power cables. These giant, obnoxious things sucked the life out of me and are pretty hard to store. My training captain told me about retractable cables. I did search the forums and saw a couple of...

    Can anyone please share a schematic of the main engine start / stop electrical circuit? My boat is a 1988 67’ cockpit motoryacht, it is very similar to 60’ motoryacht.
