Boiler install question

Hi there Heating Help, below is a pic of my 22 year old Weil-McLain P-WGO-3 oil burner for hydronic baseboard.
Saw evidence of water leak this morning, which I’ll get to, here or in another thread. But first I’d like to ask a general question I’ve been meaning to ask anyway about a replacement (which now I might need):

1. Can one person (or if I’m lucky, two), get this thing off the blocks and outside and a similar Weil-Mclain up? How in heck do you guys do it? Assuming the new one got dropped in my driveway, it’s a straight level run through the garage to the basement. But could I even move this thing with a hand truck? Your techniques? (SupplyHouse says it would weigh about 600 lbs without burner!) But most especially, how in heck do you maneuver it up on the blocks? I know it’s done every day ….
2. The current one is 15 inches off the ground on blocks. Does it have to be? It would be a lot easier to maneuver the new one into like one small run of blocks.

Now we come to the part where you ask why in heck I’d even consider doing this myself, which is a very good question. (I might not, of course, depending what I hear from you guys.)

However, in the past year I’ve done things I never thought I’d do, mostly due to help from this site: revamped my whole fuel oil supply system and converted to one-pipe, installed an indirect water heater, put in new flue pipes, tuned up the boiler, other misc. plumbing, etc. (And since then, also inspired a lot by this site, although I know it’s no substitute for experience I’ve taken Plumbing 1 & 2 at our county trade school (BOCES) and two days of Beckett’s burner course, and might take HVAC 1 & 2, although all that means I just know more about how much I don’t know. I do still ponder trying to be a plumber’s helper full or part time, but the time’s not quite ready for that yet.) Anyway, although I will get a pro to do it if I have to, tackling it myself would be a good next step and I’d like to take advantage of the opportunity.

Installing a residential boiler does seems to be on a whole other level, but the biggest challenge seems to me right now to be the physical moving the boiler part, since I figure for the plumbing part if I swap in a similar unit I’d just mimic the existing piping, (although I would try to do one of those calculations first to figure out if 115,000 btus like I have now might not be oversized). All comments welcome.

(Hi , @EdTheHeaterMan glad to see you’re still here, you and @Mad Dog_2 and lots of others helped me lot with several projects a year or so ago and I intend to update those threads to show what I ended up doing.)

Here’s the WM, (door is open to look for leak, still looking).
