But even in a tight space, there is much that can be done to make passage forward easier, particularly by making sure there are no projections  into the walkway, be it from the engine or from some other piece of equipment, like a valve handle from an oil-change system or fuel-water separator. Everyone loves the shiny diamondplate panels that typically cover this walkway. Neatness? The Steamship Shieldhall is the largest working steamship in Britain. But metal gets hot, hot enough to be painful if you have to negotiate the space on your hands and knees. Here both space constraints and trim considerations have probably ruled the day—a designer needs to keep weights evenly distributed side to side and position mass well aft to allow for good planing performance. On some boats, these valves are crucial and require periodic adjustment to ensure good running trim, but of course that means that some crewmember has to negotiate the passage forward between two hot engines to change them, at least on boats with engine-room access aft. But if you’re shopping for another boat or maybe just sprucing up the one you have, what makes a good engine room? It is a WWII era Packard 4m-2500 v-12 that came from a PT Boat. Space restrictions on any given boat are one of those things that is imposed on the designer—he can’t provide more headroom or width between the engines than the basic vessel envelope allows. The Model PT Boat Site. And you know, if you go into a man’s basement, you can tell a lot about what kind of a homeowner he is. It’s full of hot surfaces, spinning objects, and toxic chemicals, so good engine-room design starts with a reduced need to go into the place, and ensures your safety when you do. Greetings.

Two straight beams called coamings run the length of the chart house, day room, and engine hatch, and are integral to the hull. Induction System - Gear Driven Centifugal Supercharger These beams add strength and help seal water out since they rise up from the deck about 5 5/8". Of even greater concern are the genset’s remote coolant reservoir and fuel-water separator. Rubber, on the other hand, reflects little heat and offers superior traction when wet or oily. With three feet of water in the engine room, Lt. Kelly beached the boat, and abandoned it. The engines were dry sump with an … One of the three Packard V-12 marine engines that power a PT boat. So the prudent boater should think about equipping his vessel with a dedicated emergency battery (if she doesn’t already have one) that can run his VHF and other key electronics, and mounting it as high as possible.

Kennedy was rammed and sunk by a Japanese Destroyer one very black night, he was idling with all 3 engines in neutral. PT boat duty was very dangerous and the squadrons suffered an extremely high loss rate in the war. The two engine areas that present the greatest potential hazard in an engine room when the boat is underway are the two places where things are moving—the front and the back. Is it appearance? Screens shall be of solid plywood type, sliding in runners for windows, and under engine room vents, to be combined with spray shields, fitted with drains to deck. Please send me a PM. Based on the Packard 3A-2500 aircraft engine. You know, just like your basement.

A well-configured engine room will be designed and built around the main propulsion system. He is said to have heard the destroyer moments before it struck. The modelling objective here is to make an operational 1/20th scale Packard V12 Marine Engine that looks like the original V12 engine but is actually an electric motor (and possibly gearbox) housed in a cast shell and when completed it should fit the exact mounting bed of the original engine. The top outsides are milled for a small amount of … The engine has a data plate on it from overhaul in 1959. There are some more detail shots in the Higgins PT Boat Engine Room gallery that show the transmission shift lever better. Flagging its location is a good precautionary measure. If your main fuel tank is amidships and forward of the engines, as it is in many boats to ensure relative constant running trim as fuel burns off, it may have been impractical to place both the separators and the fuel valves anywhere else. Virtually all modern gensets have “single-side servicing,” meaning the dipstick, oil fill and drain, and hopefully the raw-water pump, are all on one side.

This can be particularly important in an emergency when a crewmember may have to clamber over and around the engine to access the outboard side. On a single-engine trawler, you should have at least shoulder-width room 360 degrees around the engine. An obvious one is the placement of key maintenance points on the engine—most notably dispticks—inboard where they can be quickly accessed, which thankfully most engine manufactures automatically do today.Most engines today are also equipped with remote coolant reservoirs, which allow you to check engine-coolant levels without the hazard of removing the engine-mounted pressure cap. Based on the Packard 3A-2500 aircraft engine. Special metal shutter shall be fitted on chart house door. In fact I think none of us ever looked at our engine rooms in quite the same way again, because an engine room really is a place that can define both a boat and her owner.

The rule for lighting is pretty simple: the more wattage the better. One final consideration when you’re looking at the engine-room design of a new boat is where the manufacturer has put the heavy stuff—namely the batteries and the genset. Piston Stroke - 6 1/2" Of course it’s difficult for engineers and designers to cluster all of these in the limited space that’s available, so look for the prioritization of things you’ll need to reach in an emergency.
