WEBVTT 1 00:00:01.200 --> 00:00:04.000 ...used to connect the Atlantic Ocean to the Gulf of Mexico. 2 00:00:04.000 --> 00:00:08.000 Now once again, here's the founder and host of Ship Shape TV, 3 00:00:08.000 --> 00:00:10.000 John Greviskis! 4 00:00:10.000 --> 00:00:11.700 John: Thanks Buck! 5 00:00:11.700 --> 00:00:13.700 We want to change the way 6 00:00:13.700 --> 00:00:15.700 that our engine and generator 7 00:00:15.700 --> 00:00:18.600 is getting cooling water 8 00:00:18.600 --> 00:00:20.100 to each system. 9 00:00:20.100 --> 00:00:22.100 Currently we have a sea chest, 10 00:00:22.100 --> 00:00:25.300 and originally it was fine. Our engines were a little bit smaller. 11 00:00:25.300 --> 00:00:27.900 In 1996, we re-powered. 12 00:00:27.900 --> 00:00:30.700 Okay, and we have larger engines that consume more water. 13 00:00:30.700 --> 00:00:32.600 And, we put in a new generator 14 00:00:32.600 --> 00:00:35.500 that consumes more water and the sea chest is just outdated. 15 00:00:35.500 --> 00:00:38.300 If something were to clog, everything gets shut down. 16 00:00:38.300 --> 00:00:41.800 So what I want to do is I want to bring independent water supplies 17 00:00:41.800 --> 00:00:45.300 to every unit. And that leads us to our next expert guest. 18 00:00:45.300 --> 00:00:47.100 Hello Richard how are you? 19 00:00:47.100 --> 00:00:47.800 Richard: Good to see you again. 20 00:00:47.800 --> 00:00:49.700 John: This is Richard Cozier and Richard 21 00:00:49.700 --> 00:00:51.700 is with Perko. And you guys 22 00:00:51.700 --> 00:00:53.700 are bar none the experts in 23 00:00:53.700 --> 00:00:55.300 underwater marine fixtures. 24 00:00:55.300 --> 00:00:57.700 And I see that we've brought a nice assortment here. 25 00:00:57.700 --> 00:01:00.900 For an independent water supply, to each engine 26 00:01:00.900 --> 00:01:02.900 What do I need to install? 27 00:01:02.900 --> 00:01:04.900 Richard: Basically there's two options 28 00:01:04.900 --> 00:01:07.100 as far as how you want to bring the water into the system. 29 00:01:07.500 --> 00:01:10.700 You have a ball valve and thru hull combination, 30 00:01:10.700 --> 00:01:12.900 or you have a seacock and thru hull combination. 31 00:01:12.900 --> 00:01:14.900 John: Okay I want to show everybody the thru hull. 32 00:01:14.900 --> 00:01:16.500 And what a thru hull does is 33 00:01:16.500 --> 00:01:18.700 it gives you the ability to bring raw water 34 00:01:18.700 --> 00:01:21.000 from the outside of the boat, through the hull, 35 00:01:21.000 --> 00:01:23.000 and then into the craft. 36 00:01:23.300 --> 00:01:26.500 A ball valve, notice this handle right here, this gives us 37 00:01:26.500 --> 00:01:28.500 the ability to shut off water. 38 00:01:28.500 --> 00:01:30.500 Okay and I've seen a lot of boats today 39 00:01:30.500 --> 00:01:32.500 use this combination. 40 00:01:32.800 --> 00:01:34.900 But, it's not necessarily 41 00:01:34.900 --> 00:01:37.300 the most prudent combination to use. 42 00:01:38.000 --> 00:01:40.300 Tell me the advantages of a seacock 43 00:01:40.300 --> 00:01:41.600 over a ball valve. 44 00:01:41.600 --> 00:01:43.600 Richard: Basically a ball valve - once the 45 00:01:43.600 --> 00:01:45.600 thru hull is installed into it, 46 00:01:45.600 --> 00:01:47.600 it becomes a one single unit. 47 00:01:47.600 --> 00:01:49.900 So if there was ever any sort of 48 00:01:49.900 --> 00:01:52.900 force that were to damage the thru hull, the thru hull got 49 00:01:52.900 --> 00:01:56.100 corroded or if you damage in the inside of the ball valve, 50 00:01:56.100 --> 00:01:58.100 this item would break the seal 51 00:01:58.100 --> 00:02:00.100 and you'd have water coming into the boat 52 00:02:00.100 --> 00:02:01.800 and you'd have no way to turn the water off. 53 00:02:01.800 --> 00:02:03.700 John: Even though it has a shut off handle, 54 00:02:03.700 --> 00:02:06.100 okay - if that connection 55 00:02:06.100 --> 00:02:09.500 gets compromised and if something were to hit it inside the boat, 56 00:02:09.500 --> 00:02:11.500 okay - it could get compromised. 57 00:02:11.500 --> 00:02:12.500 You could sink. 58 00:02:12.500 --> 00:02:14.500 A seacock however does what? 59 00:02:14.500 --> 00:02:16.500 Richard: Okay, a seacock, the main difference 60 00:02:16.500 --> 00:02:18.900 between a ball valve and a seacock is this flange. 61 00:02:18.900 --> 00:02:20.700 This flange is mounted 62 00:02:20.700 --> 00:02:22.700 to a mounting block inside of the boat. 63 00:02:22.700 --> 00:02:25.700 And once they're installed, they become 64 00:02:26.300 --> 00:02:27.900 one unit in the boat. 65 00:02:27.900 --> 00:02:30.300 And it allows for the thru hull 66 00:02:30.300 --> 00:02:32.200 to be able to be seated in 67 00:02:32.200 --> 00:02:35.100 and adjusted till it meets the bottom of the boat. 68 00:02:35.100 --> 00:02:37.400 And if there is any compromise to the thru hull 69 00:02:37.400 --> 00:02:39.400 you can physically turn this off, 70 00:02:39.400 --> 00:02:41.700 unscrew the thru hull from under the water 71 00:02:41.700 --> 00:02:44.300 and you have no water coming into the boat whatsoever. 72 00:02:44.300 --> 00:02:46.800 John: I want to go that route, 73 00:02:46.800 --> 00:02:48.800 but I want to talk about the threads 74 00:02:48.800 --> 00:02:50.100 that are on a thru hull. 75 00:02:50.100 --> 00:02:52.000 I know that there are straight cut threads, 76 00:02:52.000 --> 00:02:54.000 I know that there are tapered threads. 77 00:02:54.000 --> 00:02:56.700 Where do you use these different types of threads 78 00:02:56.700 --> 00:02:58.200 in marine hardware? 79 00:02:58.200 --> 00:03:00.200 Richard: Okay, a seacock 80 00:03:00.200 --> 00:03:02.200 uses straight cut threads. 81 00:03:02.200 --> 00:03:04.200 It allows for an object like a 82 00:03:04.200 --> 00:03:07.200 thru hull, to be adjusted based on the distance, 83 00:03:07.200 --> 00:03:09.200 or however it's going to travel into it, 84 00:03:09.200 --> 00:03:10.800 to the distance of the bottom of the hull. 85 00:03:10.800 --> 00:03:13.200 John: So a straight cut thread is for a adjustability. 86 00:03:14.300 --> 00:03:17.200 Richard: With using pipe dope and/or teflon tape 87 00:03:17.200 --> 00:03:18.900 you can create a watertight seal 88 00:03:18.900 --> 00:03:20.900 but this seal is not as important 89 00:03:20.900 --> 00:03:22.400 as a tapered thread 90 00:03:22.400 --> 00:03:25.400 for something along the lines of a ball valve. 91 00:03:25.400 --> 00:03:27.400 Now a tapered thread, 92 00:03:28.700 --> 00:03:31.500 after the first several turns, it will lock up 93 00:03:31.500 --> 00:03:34.500 and seize and it will create a watertight seal. 94 00:03:34.500 --> 00:03:37.500 John: So a tapered thread will self seal. 95 00:03:37.500 --> 00:03:38.300 Richard: Correct. 96 00:03:38.300 --> 00:03:40.300 John: But we do recommend that you 97 00:03:40.300 --> 00:03:42.000 would, even with the tapered thread 98 00:03:42.000 --> 00:03:43.800 even though it's suppose to self seal. 99 00:03:43.800 --> 00:03:46.300 Use some teflon tape in order to ensure a seal. 100 00:03:46.300 --> 00:03:50.100 But the tapered thread is used for a ball valve install, 101 00:03:50.100 --> 00:03:53.400 the straight cut thread is used for seacock install. 102 00:03:53.400 --> 00:03:55.400 Richard: Correct. Now Perko's thru hulls - 103 00:03:55.400 --> 00:03:57.400 we've created a combination thread. 104 00:03:57.400 --> 00:04:00.800 Which the first several threads on our thru hulls are tapered 105 00:04:00.800 --> 00:04:04.400 the balanced are all straight so it can work in multiple applications. 106 00:04:04.400 --> 00:04:06.400 John: Alright I want to talk about scoops. 107 00:04:06.400 --> 00:04:08.900 We need to have a way to strain out 108 00:04:08.900 --> 00:04:10.900 seaweed or grasses 109 00:04:10.900 --> 00:04:12.900 that might be found in the body of water 110 00:04:12.900 --> 00:04:14.700 or around our boat. We don't want that entering 111 00:04:14.700 --> 00:04:16.700 into our engines because that could clog them. 112 00:04:16.700 --> 00:04:19.000 Okay, that could create an overheating situation. 113 00:04:19.000 --> 00:04:22.700 Talk to me about this particular casting. 114 00:04:22.700 --> 00:04:25.000 Richard: Okay, this is a scoop strainer. 115 00:04:25.000 --> 00:04:28.400 It fits with a thru hull inside of it like this and it forces, 116 00:04:28.400 --> 00:04:31.600 this is on the underneath of the boat at the hull of the boat. 117 00:04:31.600 --> 00:04:33.600 John: And this faces forward as you're traveling forward. Richard: Correct. 118 00:04:33.600 --> 00:04:35.700 Richard: It forces water into this direction 119 00:04:35.700 --> 00:04:38.200 up your thru hull and into seacock or ball valve. 120 00:04:38.200 --> 00:04:39.800 John: Okay, so it scoops it in, 121 00:04:39.800 --> 00:04:41.400 and it forces it up. Richard: Correct. 122 00:04:41.400 --> 00:04:43.400 John: Alright it also strains out 123 00:04:43.400 --> 00:04:45.600 some of that garbage that might be in the water. Richard: Correct. 124 00:04:45.600 --> 00:04:47.900 Richard: There's different types of strainers that have 125 00:04:47.900 --> 00:04:49.600 the holes like this. 126 00:04:49.600 --> 00:04:51.800 This is a better operation for being able to 127 00:04:51.800 --> 00:04:54.800 strain versus this which is more of a water flow. 128 00:04:54.800 --> 00:04:56.800 John: What are the baskets all about 129 00:04:56.800 --> 00:05:00.000 that you've seen inside the crafts with the glass bowls? 130 00:05:00.000 --> 00:05:03.600 Richard: We have here an example of one of our water strainers. 131 00:05:03.600 --> 00:05:05.600 And basically the main difference with this 132 00:05:05.600 --> 00:05:07.600 is this allows you a visual reference 133 00:05:07.600 --> 00:05:09.900 to be able to see your water flow that's going. 134 00:05:09.900 --> 00:05:12.600 If you have a back up that's happening and it's in your 135 00:05:12.600 --> 00:05:15.100 basket, it's easy to change. 136 00:05:15.100 --> 00:05:17.400 John: So you can clean out the debris that get 137 00:05:17.400 --> 00:05:19.000 caught in this basket. Richard: Correct. 138 00:05:19.000 --> 00:05:21.000 John: Okay, but more importantly you can see 139 00:05:21.000 --> 00:05:25.600 the water flow going through this glass sphere, okay. 140 00:05:25.600 --> 00:05:28.300 Coming to the engine, you can tell in essence 141 00:05:28.300 --> 00:05:29.600 if your water pumps are still working. 142 00:05:29.600 --> 00:05:31.600 John: Okay that is very, very cool! 143 00:05:31.600 --> 00:05:33.600 Now if your temperature gauge goes up 144 00:05:33.600 --> 00:05:35.600 and you don't have one of these, okay. 145 00:05:35.600 --> 00:05:37.100 Chances are 146 00:05:37.100 --> 00:05:38.900 your scoop has been clogged. 147 00:05:38.900 --> 00:05:41.200 You're going to have to jump overboard and have to clear it. 148 00:05:41.200 --> 00:05:43.700 Otherwise you're going to get into a real serious situation. 149 00:05:43.700 --> 00:05:45.700 Richard, thank you so much for all the 150 00:05:45.700 --> 00:05:47.700 information. We're going to go with seacock. 151 00:05:47.700 --> 00:05:49.900 And we're going to show you step by step procedures 152 00:05:49.900 --> 00:05:51.700 how to install one into your boat, 153 00:05:51.700 --> 00:05:53.700 right after this! 154 00:05:53.700 --> 00:05:55.100 Narrator: Don't pull up anchor! 155 00:05:55.100 --> 00:05:58.600 Ship Shape TV will be right back!
