Trouble on the high seas

the sail to mazatlan :
The Wind was  just off our nose, so we choose to sail, so we fall off 20 deg. heading toward land a bit but it's 15 miles off. Loosing ground we tack we are much worse on the starboard. we descide to fire up the engine. Something does not sound right, if you listen to the exaust it should have a wet sound every 5 seconds or so, no water!!. I run down below check the bilge, where is the water, engine is cooled by sea water, through a heat exchanger, bilge dry, hoses in tack. Kim yells, who now is on the helm, temprature is up, and then the alarm goes off, we are 200 deg, we run 165-170. Kill the engine, sail still up we have control of the boat, 2 to 2.5 sea 9 kts of wind. what now, check the strainer could be fouled. It's now getting dark. We had to clean the watermaker intake in Chamela, things were growing in the throughhull Nikita dove to clear it.We found  a little slim in the strainer, but not enough to give us grief. Must be the impeller in the raw water pump, or, the raw water pump, which we changed in back in LA 6 months ago. God please don't let it be the water pump, our spare is the used one we took out. Kim informs me the swell is knocking her off course, we are headed for land. It's now dark, it goes dark within 1/2 hr of when the sun sets. We call in the mechanic "Nikita",who watched the guy up in LA change the impeller and later the whole pump. We have a new impeller.I pass wrenches Nikita takes the cover off, 6 bolts and 2 brackets, we are rolling around on the seas and its now dark but he knows this area well, one of the hoses that gave us trouble when Victor was down starts here.
Nikita says Oh my god, yep it's the impeller, it's missing 2 fins out of 8. Now if you've  never taken an impeller out and did not read the maintanence manual you would never get that sucker out,2 screwdrivers with equal pressure, amazing, it's out. we grease the new one it goes in wrong,we must take it out,carefully.2 fins need to be compressed. It's in, we close up, fire up, we have water!! Kim has been trying to keep us on coarse 1 1/2 hrs. we are releaved it could have been worse,like the heat exchanger.......
Nikita takes the early watch with Kim, I grab some shut eye, my watch 12 to 2 and 4 to 6, Kim will take 2 to 4 and Nikita will take 8 am. I made it to 3 am then stayed up to keep Kim company, she let me sleep till 7:30. Kiya was up by 8:30 and got to see the 40 or so dolifins that came out to greet us , some stayed swiming at the bow just under Kiyas' feet. As we approched the Mazatlan harour,with 2 cruise ships,and a hugh ferry from the Baja in dock.we ended up arriving at the same time as a cargo ship, we fell off ,so did he. A huge fishing trawler comes steaming out,cuts in front of us 200 yds and steams off. we radio in to the harbour master who requests us to stand off for 1/2 hr. pilot tugs come and guide the cargo ship in. this thing is several blocks long, the deck is high 200 ft the bridge is windows in the bow of this monster. we ask again for clearance, are given it, and follow a small ferry in. The anchorage is right inside the break water to port. Our friends "Gota Go" lay at anchor with a few other boats. Everyone is up as Kim and I crash for a power nap.We made it, crew all acounted for and vessel in tack.
