I did replace with the 20mfd, as two were listed. Another friend suggested I upgrade to the 25mfd also. Thank you for the heads up!

I am swapping over to a 25uf. Other one seems to be dragging in pulling in the contractors.

I am going to swap out for a 25. The 20 is dragging its feet kicking in the contractors.

UPDATE! UPDATE! UPDATE

Well, today I spent my time in the bilge. I replaced the starboard alternator, only to find out it was a broken wire. OK, I now have a spare. As for the Genset........I got the new governor spring, and replaced it, still a light surge. So i tightened up the slack spring by taking a couple turns around on it Now only a surge for the first 2 minutes of running until it gets warmer up. Checked the impeller and it was new as stated. Ran water back from the heat exchanger to the raw water pump, no restrictions so I believe it is clear. Removed the control box, and replaced the capacitor. I still hadn’t gotten the 25uf’s yet, so replaced with the spare 20 I had. Lastly I recrimped the connections to the temp sensors. Then I poked around. I believe the water temp sensor is bad. It wiggles in the crimped brass threaded part, one is on order. Then I checked the coolant in the heat exchanger(new winter 2018)/, sw it was low! So topped it off, didn’t take much, but nonetheless, i is now full. Fired it up and after 90 seconded she purred well, placed a load on it and no surge, just hunkered down to business. Ran it for 45 minutes, no issues. Cured? WHO KNOWS! But it isn’t shutting off on its own anymore!

Date Line 7/17: We had to try out the Genset after all I went through with the shutting down issue. I replaced the capacitor. However I believe the main issue was it was doing what it was supposed to do, shut down on over heat. If you remember I saw the heat exchanger was empty of coolant. I refilled and cleaned and wiped the tank sealing surface and the rubber on the cap. I ran it yesterday for 3 hours, and this AM for 2. So far all is well. I checked the coolant in the exchanger this AM Nd it was full and drawing back from the recovery tank. I believe we are back on the power generating business.
