Replaced the hose last spring. I used a piece of "Marine Water/Exhaust Hose (with Wire)" from West marine. It was either 1 7/8 (part # 227140) or 2" (part #227157). The original hose had wire and my boatyard wanted to sell me stuff without wire. I have no idea if the wire will ever matter.
It was a very tight fit as the original hose was actually glassed in somewhat with some of the tabbing that holds the engine pan in. Had to chip the origninal hose out a bit.
I used that drippless packing in the stuffing box. That is very nice!
