2000 340 7.4 ltr. MPI. Had both done a couple years ago, now starboard is not pumping water. Pretty sure I can squeeze in there and do it myself. Want to make sure i get the right one.

These are inboards. Same impeller?It's just a "Bravo 3" impeller. Buy three of them - replace the impellers in both engines and keep a spare onboard. Make sure you extract all the pieces of broken blades.
Actually, I did the starboard once a long time ago. Attempted the port and half way thru I said "fukkit" and made the phone call. Could they have put them in a worse spot, like under the tranny?!Get yer bottle of whiskey ready. The pumps on your 340 are in a wickedly horrible location. You will not likely enjoy this project. It's going to make you want an older 400. ha
I went down today and figured I'd start the project. First bolt on the bracket (lower one) was tight, but gave a bit then seemed to move a little better. After a couple pulls on the (3/8") ratchet it came out and fell in the bilge. I think it broke! If it did, it had to have been weak to begin with for a 3/8" ratchet to snap it. I have to bring a magnet down now and try to fish it out to confirm. I didn't get to the upper bolt as I didn't have a 5/8" open end on the boat. To use a socket I'd have to pull a coolant hose, which I'm trying to avoid. Updates to follow.
