Despite doing 10 or 20 boat projects over the past 5 weeks, I'm running short of time to do everything before I launch on the 27th. I've done thru-hulls, running rigging, blahblahblah, new batteries, overhauled the entire sanitary system, and I'm in the middle of rub-rail leak fixing. The next week needs to be devoted to finishing the rubrail and painting the bottom. Our H306 has been on jack stands since November 2016, so I need to do several engine projects too.
Engine projects (2GM20F) done so far:
1) new batteries
2) new Groco sea strainer, thru-hull, and related hoses
3) installed new impeller, checked the raw water pump, smoothed the interior surface
4) added a very small amount of water (4 oz?) to top up the coolant
5) started and ran the engine on land for a minute or two. Started on the second try, despite 3.5 years of idleness!!! Ran flawlessly.
Want to do:
6) change primary fuel filter
7) change secondary fuel filter
8) flush and fill with new coolant
9) maybe new belts
10) maybe hire fuel polisher. Or maybe buy a cheap borescope to check the fuel tank.
11) remove and inspect the mixing elbow
12) change oil(s)
My conservative instincts tell me that since it started and ran flawlessly, I should launch first and drive it around the corner to the slip before doing the rest of the work. In particular, I want to change the coolant, but I don't feel comfortable running the engine very long on jack stands, so it makes sense to me to do this once I'm in the water. Please confirm or criticize!
