I have a battery charger that takes in 12 volts and puts out 24 volts to charge the batteries for my bow thruster which is 24 volt. The charger has been working fine for years. I was re-routing some of the wiring in the engine room and disconnected the charger so I could connect it to the main...

I have two Sunpower 327 watt panels that I plan to put on the fly bridge hard top wired parallel. I want to use an MPPT controller mounted about three feet from my 12 volt house bank. The wire run from the panels to the controller is 35 to 40 feet. Any suggestions on brand/size of controller...

Japanese fishing boats in Mitsuhama, Japan. Looks like they have added length to the bow to get more waterline length so they can go faster?

Just installed a Water Fixer UV sterilizer/filter in the house water line immediately after the pump/dockwater connection. I really like the taste of the filtered water but the water pressure dropped significantly (oddly the drop in pressure is more noticeable when using the city water than when...

Does anyone know how the exhaust was originally routed on the 36? Did Gulfstar use waterlift mufflers? In particular I'm interested in knowing how the port exhaust was run. My 4-154s have a 2" diameter elbow with 4" diameter hose connected to them and no waterlift. On the port side the hose...

As you can probably tell from my other posts I'm doing some rewiring, moving things around and cleaning up old/non-marine wire. My 3000 watt inverter is wired to the house bank with 4/0 cable. The wires going to the 12 volt house panel (pos) and engine block (neg) are the boat's original 1/0...

Was thinking of these for engine room, really good price but I wonder if they will run on 12 volts? Feit Electric 4’ LED Shop Light This 4ft. LED Shop Light requires no lamps to replace and lasts up to 50,000 hours. Perfect for hanging or flush mount installation. They are ideal for use in...

I have a 12 volt windlass and a 24 volt bow thruster with two 12 volt batteries in the bow wired to make 24 volts. The windlass is wired to battery bank in engine room and the cables are long and undersized. Any suggestion for wiring the 12 volt windlass to the 24 volt bank so the cables will...

Just curious why most twin engine displacement trawlers have engines that are the same hp as would be used if the boat had a single screw? For example my 36 fd trawler has two 62 hp engines. Since 62 hp is more than enough power to cruise at hull speed wouldn't it be more efficient to have two...

Although the old perforated automobile style headliner in my aft cabin is in fair shape, the plywood behind it that was (I think) glued to the underside of the deck has come loose. If I take out the headliner, I'd like to insulate and replace with something white and easily cleaned. I like the...

I'd like to elliminate the hoses in my vacuflush system in favor of pvc. My question is, can I use standard pcv 90 degree fittings or do I need to find 90 degree sweep fittings that have a more gradual bend?

I'm in St. Petersburg for the weekend and was thinking about tracking down where the original Gulf Star boatyard was. Does anyone know the address? Also, I've always wondered what happened to the hull molds? Sorry, I probably should spend more time thinking about less obscure things. ?

I have one tankless hot water heater heated by the webasto hydronic heating system and one electric/engine coolant heated tank. I have to go to the engine room and turn a selector valve to use one or the other. I am thinking about plumbing them in series with the tankless unit feeding hot water...

I have had two different boat yards tell me the transom on my boat is too thin to support a swimstep yet I see many Gulf Star 36s with swimsteps? Is the transome re-enforced?

I notice the forum assigns monikers to members like "Newbie", "Member", "Guru", etc. what do they mean? Are they based on the number of posts? BTW- this is the best forum on the web!

I've heard that you can burn used oil by mixing it with diesel. Has anyone done this? Drawbacks? Does it make a difference if you run it through an older engine vs. a more modern one?

Looking at the exhaust on my Gulf Star 36 Trawler with twin 4-154 Perkins (60 hp). The exhaust manifold/water injection elbow is 2" diameter and about 9-10" above water line. Attached to the elbow is 4" diameter hose running along the chine of the hull aft to the mufflers and out through the...

I currently have two 4D batteries used for starting two Perkins 4-154 engines and serving double duty as the house batteries. I would like to set up a seperate house bank and have two smaller batteries used exclusively for starting the engines. My engines start quickly, they only need one or two...

I have a Gulf Star 36 and the gasket materials in the salon window frames need to be replaced. It looks like two tracks of felt with a wire backing that fits into a U shaped channel allowing the windows to slide back and forth in the felt tracks. I can't find anyone who sells the materials. Any...
