Title tells the story. I am about to coat the sheet aluminum top to my fully enclosed upper helm with a 100% silicon roof coating. Am I crazy? I will add play sand to provide a less slick surface to walk on when it is raining should I have to go up top. I have considered an acrylic coating...

After 8 years on the "hard", with little TLC, and 3 years in the water - never leaving the dock, having received many valuable suggestions from the many knowledgeable members of this forum over the last three years and the help of Brian, from Shipwright Harbor, Deale, MD, I just moved my 45 year...

My upper helm and aft doghouse cover is fabricated of welded square aluminum tubing with pop riveted aluminum sheeting, covering the frame. It is strong and can be walked upon without issue. While installing insulation enclosed by pvc bead board to the underside of the aft doghouse cover, I...

I have two engine alternators, two start batteries and one house battery. The start batteries are isolated/combined/controlled by two battery switches and can be attached to Port, Starboard, or Both engines. The House battery is isolated, with no cabling connected to the start batteries. I want...

On a recent move to a new marina, I noted that one of my two engine alternators was not working. To keep both start batteries + the house battery charged, I combined the two start batteries using the battery switches - set to both - and the house battery with a jumper cable. My Port alternator...

Anybody know where I can buy one? Mine is broken off just below the max full line. If you don't I will get a piece of steel welded on to match my other engines dip stick. Thanks

I am changing out the fuel filters on my two T6-354 Range 4s. I checked a video and the mechanic just pushed the top gasket/o-ring up into the base and it stayed:banghead::banghead::banghead::banghead: My top o-ring/gaskets just fell out. (They were the correct (larger) o-ring/gasket of the 3...

Some time back I experienced some exhaust coming from my insulation covered port turbo exit flange. Upon closer look I found major deterioration to the bolts, flange, etc. I removed the "L", replaced a couple of studs in the turbo exit flange, and cleaned up the "L". I reinstalled and...

When I push the start buttons, my perkins' starters sometimes turn, other times don't. I used two remote starter buttons to start and stop the engines from the engine room. They both start immediately when I attach the buttons directly to the solenoid terminals, the neutral safety switches, and...

Situation: I have two terrific old perkins. I have an upper helm and lower helm, with 4 morse control heads. There are two separate cables - transmission & throttle - at all four morse control heads. Upper and lower cables run all the way to the transmission and throttle. Upper and lower helm...

While replacing the wet exhaust, fuel filter, hoses and belt on my NL M753, I discovered the foam insert in the air filter has deteriorated and the screen is missing. A replacement air filter screen and foam insert costs $130 - WOW! I'm thinking about fabricating the filter screen & "foam"...

I'm finally getting ready to clean up & RE-DO my engine compartment. The plywood floors have been in place since '79. Under the two, 200 gallon tanks and under & aft of the generator, are areas where plywood floors restrict access to the inside of the hull. Over time, the hull, in these...

My 1979 Ocean 40+2 Trawler had two Cruisair 16K BTU ACs. One is a split system with 2 evaporators: one in each of the fore and aft cabins. The second is split system with one evaporator in the salon - over the refrigerator, near the aft companionway. Both condensers are in the engine...

I replaced one Cruisaire 16000 BTU condenser with an Ocean Air condenser a few years ago. I am planning to replace the second Cruisaire 16K BTU condenser with an AC installed under my settee in the main salon w/AC duct running to the location of the current Cruisaire evaporator. The concern is...

I bought an old boat - '79 Ocean 40+2 trawler - 15 years ago! I've been working on everything else for 15 years:) I recently pressure washed the port engine area and bilge and painted anything that was rusty. While doing this task, I noticed that, under the plywood floors the hull interior is...

When I fill the fresh water tank it takes about 70-80 gallons of water. Then, I notice about 30 gallons of fresh clean water in the forward bilge, yet the pressure water system still provides water to the faucets and water heater. So, I assume the tank has a leak, probably on a corner, midway...

I am just starting to trouble shoot this problem. They have not worked since I bought the boat, many moons ago. I suspect worn out senders. I provided a picture of the top of the sender on the starboard side. Can anyone tell me what kind of sender this is? I don't see a name or number. Duh...

2 banks of new batteries. #1 bank is two group 24s starting batteries in parallel with a total of 1600 CCA. #2 bank is 2 deep discharge golf cart batteries in series. Cleaned up and/or replaced all battery power and ground cables. Cleaned up all generator and alternator connections. Cleaned...

While replacing the exhaust manifold gasket on my NL Generator I found slight pitting on the expansion tank surface between the expansion tank and the head. I found deeper pitting on the expansion tank where the elbow is attached. I think the new elbow will seal with the new gasket, but may...

I have a pair of Sierra Docking Lights on my 1989 Ocean 40+2 Trawler that haven't worked since I bought the boat in 2009. Just removed the back cover and found a strange rubber encapsulated light bulb (I think) that has to be removed from the outside. I am in the water so that is a challenge...

I'm looking for a little wisdom - and experience - changing over my 43 year old analog gauges at my upper helm for digital and a PC display. I've got 2 old Perkins with no modern data harness to support such a plan. I'm thinking I would move the analog gauges to the engine compartment, possibly...

I recently put my '79 Ocean trawler in the water after a long lay up (8 years) and discovered water in the port velvet drive. The water has probably been there for years. I replaced the oil cooler, pumped out the tranny twice, replaced the ATF, and ran for 2-3 minutes. Though it shifted...

I have a port engine velvet drive transmission with a slow drip at the back of the reduction gear - just in front of the reduction gear-to-prop shaft flange. I suspect the rear seal. I've disconnected the prop shaft flange from the reduction gear flange and the prop shaft turns freely - but...

My cast iron wet exhaust fell apart from rust. It shows 400 hours over 40 years. The boat has been on the hard for 8 years. I relaunched in September, 2021. I removed manifold/expansion tank and found lots of black diesel residue in the #3 exhaust port. I found even more hardened diesel residue...

I am trying to verify the operation of my 1979 Ocean Trawler water level gauge and sender. It is a VDO, 1979 era. I attached pictures of a similar gauge's diagram, the gauge, and the sender. 1. The terminal configuration on the back of the gauge is like the 3rd version shown on illustration D...
