The end of the hose that I can see looks okay. I think there is a hose inside the bell housing (not sure if this is the correct nomenclature) that could have a flap problem.Posted by Lazy Daze...Try this: While standing on the ground, take the nozzle off your hose and hold the hose end vertically. Does that column of water (which is now exiting the hose) still make it to the second floor? Actually water would make it to the second floor again, once it fills up enough of the world.
The hoses and water flow are basically horizontal between the transom and water pump. The water pickups/muff are a couple feet lower than this so you lose a couple psi due to increased head. Set all the hot water heater and garden hose stuff to the side. If you muffs weren't leaking like a sieve you should get water flow from the disconnected inlet hose unless there is an obstruction. Other than anything you may have done in the process of r/r of the drive the only thing I can wonder about is the condition on the hose itself. How does it look? Is it possible there is a flap of deteriorated hose that blocks flow from one direction?
At this point, I intend to rebuild the water pump and measure the water flow according to the engine manual volume test. If it passes I guess it's okay. If not, I'll take the out drive off for a look-see.
