    Both engines will probably need new water pump impellers. Also check the gearcase oil for water intrusion. If no water, fill them with marine gearcase oil. If you see water, seals may need replacing. I’d let the CD soak some more and recheck compression. Compression isn’t bad, just a little uneven. May even out with running. You may want to pull the exhaust cover and check the pistons/rings.
