This hassle with the 180 turn is why I changed to a plastic strainer. I put the strainer on the bulkhead above the water line, ran the inlet hose from the seacock up and a little forward to the strainer, then ran the outlet hose over and down into the raw water pump. This straightened out the pathway, eliminated several feet of hose and made more room for access to everything. It also put the transmission cooler on the pressure side instead of the suction side of the raw water pump, which eliminated a second 180 degree turn. Much cleaner installation and a failure of the strainer can't sink the boat if I leave the seacock open (which I don't). It also makes it easy to go to a straight through hull fitting and, if you suck something up into it, you can unhook the inlet hose from the strainer and push the offending item out with a swab handle without filling the boat with water, much like the cleanout tower on a jet boat.

The Dreaded Previous Owner had used Schedule 40 plastic pipe elbows with a couple of lengths of Schedule 40 pipe that the hoses fitted over. No barbs. Under pressure, the hoses popped off constantly. I went to Fisheries, rummaged in the bins, and put together everything I needed for about $50. Beware, however, that these fittings are pretty hefty; make sure you have clearance to install. I had to rejigger my heat exchanger a little. Fisheries Supply: http://www.fisheriessupply.com ; 800-426-6930 between the hours of 8:00am - 5:00pm (PST) Monday - Friday. On the first page is a search box. Enter "brass elbow". The search result will give you 5 item headings. The first heading is Plumbing Fittings (Brass). Click on "View ALL 49 items". A 1 1/4 inch 90 degree brass elbow (female threaded) is Order No. 196, ACB 90EL11/4. List price $16.11, your price $14.50. You need two for a 180-degree turn. Going back to the search result page, the second result is Vetus Denouden Brass Hose Barb Adapters. You need two adapters to connect your hoses to the elbow. You want Order No. 197700, DEN SLP11/432 1-1/4" - 32mm BSPT Tapered Pipe Thread, list $7.75, cost $6.82 (but see below, there may be an issue with incompatible thread size). You'll also need a 1 1/4 male pipe nipple to connect the two 90-degree elbows together. Order No. 00244, ACB 11/4XCL Close 1-1⁄4" NPT, list $12.07, cost $10.86. Run a new search for "brass nipple". The result will be Plumbing Fittings; click on all items to find the one you need. The Web site lists everything except the hose barbs as in stock. I think this will work, but you might want to call them and be sure that the Vetus Denouden hose barb adapters will screw into the ACB elbows. The hose barbs are listed as British Standard Tapered Pipe Thread, and the elbows and male pipe nipple are NPT (National Pipe Thread). NPT is 11-1/2 threads per inch and BSPT IS 11 per inch (like I knew that - thanks, Wikipedia!). Might not matter, since you're not going to be using more than about 3/8ths of an inch of thread, and you can put it in your bench vise, get your big ol' pipe wrench, and mash the hell out of it since you're never going to be taking it apart.
