I took a tip from a Don Casey book and changed my intake ell to a tee. That let's me do a few things. I can rig up a hose and run the engine while on stands and that let's me test run the engine and transmission before the travellift pickup. I also can winterize easily in or out of the water. I can also check the intake in the water by closing the seacock, pulling a plug and opening the seacock. If water gushes in, it's clear. If not, I can stick a long wooden spoon handle thru it to clear it. Never had to do that, but it's nice to have that option. Casey recommends changing all thruhull ells to tees for this reason.
