The Fuel pressure switch (that powers my STBD Hourmeter), on the outlet of my spin-on (secondary) fuel filter, is spraying fuel with the engine running. I have spare switches. Based on my rudimentary but expanding fuel systems knowledge, I believe can simply remove and replace the Honeywell...

Troubleshooting involved wrapping various cleaned parts with clean paper towels and running, then looking at oil patterns. Leaking only seems to happen when in gear and pressurized. The rate of leakage seems to start heavy when shaft spinning but that maybe because oil is pooling with pressure...

Looks like I have several decision points with my boat in the water: 1) decouple shaft and push as far aft as possible and try to repair shaft seal. 2) if there's not enough space to repair, then either: a) jack or lift aft end of 8V92 and gearbox toward ER ceiling (there's 8-9inch...

Thanks Capt Ralph. I should have measured that dimension when I had the rudders repacked JUST 8 months ago--hope to not haul it again (and drop the rudder again) to get to the gear seal. It looks to be about 8inches based on my best photo and the drawings. Not sure if that's enough. Does...

My starboard gearbox has started flinging oil out of the coupling joint. it looks like the outer seal is not leaking. I suspect the inner flat rubber O-ring ("Lathe Cut Ring" M2074S) is the culprit. Does anyone know if I have room to service this without dropping the propshaft or lifting out...

My 8V92TA Engines are almond and my ER surfaces are grey and need a repainting. The oilpans and undersides are in the worst shape. Current plan is to cover the hoses/wires in aluminum foil and tarp the bilges & decks. remove the AIRSEPS and cover the inlets. Run room fan for ventilation. Clean...

Here's my Comms cabinet now: I "Cut the Cable" 4 years ago at my house and haven't looked back. My four boat TVs are are streaming off of my PEPWave LAN wirelessly as I am lucky and have great marina wifi. I've pulled out all the DirectTV receivers but planning to keep one coax per TV to...

As I trace a VHF whip antenna coax to add AIS through wire chases, I'm getting frustrated as I find my coax leads down to my circa 2005 stereo/computer/comms cabinet and disappears in a maze of coax and eithernet: I'm looking at all the very nicely installed (in a 2006) over-the-top refit...

Need to get to Shorepower Source 2 fuseholders, receptacle and cable. I can see the bottom of the aluminum box they are in from below from down in the salon but can't get into the box from the back. If I remove all the 12 or 14 hatt square head screws and pry off the panel from the sealant...

I need to clarify. The traditional classic plastic cased battery is about the size of a Lead acid 4D (but 20lbs lighter) The option I'm considering uses that same lithium cells and internal BMS in a rack mount: The Rack option upside is compactness and ease of install, as well as each...

I'm refitting some shelving and electrical components in the cabin in preparation for hopefully a lot of salt water cruising. I notice the 12 year old component stereo stack near the main salon door as well as the DVD/blue ray players, etc through out the boat look brand new, with zero sign of...

I'm moving homeports for my 52CMY from Houston to east coast, cruising from Florida, the islands with new homeport in the Chesapeake bay. I had good results with Petit Trinidad Pro hard paint here in Galveston Bay but I'm getting paint blisters (faulty barrier coat) so it's all coming off for...

The PO had the my boat blasted down to bare fiberglass, the fiberglass blisters repaired, and top of the line Pettit Trinidad Pro barrier coats (2) and top coats (4) completed in 2018. In august last year I hauled out and noted that I most of my paint is in good shape but there are several large...

Found perfect replacement at Home Depot ($11/wheel) in grey urethane with those precision bearings. Will need to toss out the stainless cylindrical bushing as the new wheels are 3/8in bored, but as the new wheels have actual bearings instead of just an axle bolt, it should work well if you just...

My port Fresh water tank sending unit has bad out-of-range ohm reading (319ohms) and I want to replace or repair. How does it come off? Does it unscrew? Hoping not to break the tank fitting but can't tell how it's installed. I assume it's a WEMA and that Sam's has the correct replacement for...

Unwinterized yacht in arctic Texas-Questions for my Yankee Hatteras friends & experts My redundant contingency plans for a historic Texas winter storm fell through. My prior visions of being onboard to test and opcheck genset, inspect lines and remove liquids less than 80 proof from the aft...

Update. I ordered a replacement FAULT RESET Shunt CB (Cummings Part number 0320-1139 from Cummings Southern Plains). Installed and now CB pops after ~3 seconds of cranking, as engine fires and begins to start. (so slightly different behavior but same issue) Here's the new CB in pic below. The...

What were the symptoms of a bad Fault Reset button that you experienced? My Fault reset is popping is when I select START--the Engine continues to crank without starting after the button pops out. Please confirm this is the component that failed? I've pulled the front and the top of Onan...

I'm new to this forum and amazed at the great info i've acquired as I've lurked in the shadows for the last year since I purchased my new-to-me 52CMY. I'm saddened to learn in the last 48hrs how unsupportable my old Onan 20 MDL4 has become over the last 10 years, if I have parts issues. It's...
