Have you re-powered? What was the total cost and what did you do?

Have a 350, thinking about a 383..
If you guys don't mind what was your total cost and what part of the country are you from? Want to make sure I get a competitive rate.

Reman 350 long blocks are in the $2300 range. Swap out the intake, accessory drives, oil pans and valve covers with gaskets and such would add about $400 each engine. R&R somewhere around $800 each side, depending on the boat. New engine controllers could add $2000 unless they can be flashed. New DP props maybe another $3000? Sounds like $12,000 minus whatever I could get for the 5.0 long blocks used.
270hp vs 320hp. Is there enough to gain here worth the $12,000?
This is for the fresh water cooled 383
I can get the 383 not fresh water cooled for 13654.. that's a little bit easier to swallow.
The third option is to just replace it with a regular 350, anyone know what those go for?

prob get a reman stroker from them too, just get ecm flashed
for $13k, and with an alpha- you should be able to get a spanking new (SEI) outdrive along with the engine. it's just a matter of looking around.
what is your boat? what kind of facility are you going to need to swap? I built a gantry and put a winch on it- 16' high and 14' wide... I repowered and slapped a new SEI A1G2 for a total of about $5k...
if you're already set up with a SBC (you are) it's a matter of pulling and replacing...
pull drive... pull shift plate and throttle cable... pull battery leads... pull main harness... pull fuel lines... pull two bolts (transom plate) and two buts (engine mounts)- yank that rascal out of there... there is no reason the engine can't be pulled in less than an hour... it isn't hard at all with the right facility.
drop the new engine in... if you're dressing a long block, do it with the engine on a stand(s)....
now this will be controversial... but... if you currently have MPI, you can either send the PCM off for flash, or, you can use a calculator and install bigger injectors... the difference will only be a pound or two tops- or, if you like cc's per hour better- the difference between 235cc and 260cc or so... and the kicker is you may need to do both (flash+injectors) anyway.
You can do this with a reputable engine for under $10k if you slow down and miss the fall pull outs.
I got a great deal on my 99 270 back in '08, buyers market. My rationale was to put a $13K engine in it as an upgrade opposed to drop $75K on a used boat that would depreciate and have mysteries, eg bellows, transom leaks, etc.
I am in the Northwest. You didn't say what type of boat you would do this too so likely more info here than you need. Just some considerations I ran into. I did a twin engine re-power on a Pachanga in 2012. replaced twin 350 mags and gen I Aplha drives. I got bobtails (both engine and outdrive) with Mercury Marine 357 4V Alpha's (275 HP) and gen II Alpha II outdrives. Went from both right hand to counter rotating props. I had the dealer do it. Labor was actually not bad. Took them forever though and as others noted, I did in summer and might have save a bit had I done it through the winter. My cost installed $34K. 3K was labor. I did extras like steering/exhaust, risers, so my guess would be 8-10K for a single 357 4V installed using existing drive and not a lot of "other stuff" with the swap. 15K for bobtail.
Considerations -
Exhaust -I had to pay an additional 3K for a custom stainless exhaust collector because the old 350 mag risers were spaced (2-4 inches?) different that the new mercury marine 4V alpha motor.
Steering - Consider switching from Cable to hydraulic steering especially if you up the HP and run in the 60s or above.
Drives - What are the gearings of the current outdrive(s)? If you go up to a 383 how will the current outdrive handle the power and how will the performance be affected? Can the current outdrive handle 330 HP?
Warranty - Going through a certified Mercury Marine dealer/shop will get you at least a 2 year warranty. Mercury Marine was running a special back when I did it and I go an additional year of warranty for a total of 3 years. BTW - Who ever does it, take lots of pictures before it goes in. Even good mechanics 'break' things they may not always tell you about. In my case, several things. Also, discuss up front the follow-on wringing out the bugs after then install. Get a commitment they'll cover this under existing cost.
extras - Plan 10-20% more that you expect because they're going to find other things wrong as in my case, the exhaust collector problem.
The Mercury Marine 357 4V or the 383 Scorpion are great engines. The 383 is "mostly" a direct fit for a 5.7L or even a 454 and puts out same or more horsepower. There are LOTs of things to be wary of when you do this kind of thing. The more research you do, the better decisions you'll make.
block cracked etc ?
So the final verdit on this is they hope to have it done by next Friday.
Total cost is going to be 15,532.
That's the 383 stroker with freshwater cooling + a 600 dollar new riser. I've heard the motors are supposed to come with these, but my mechanic says they dont and when I called mercury they also said they dont.. so oh well .
It's pretty pricey, but the guy went an picked the boat up, hauled it to his place and is trying to get it done the week before labor day. The estimate is 30 hours of labor, we chatted about that and he's hoping it's no more then 25. We'll see how it goes.
So I guess I now own an almost 40,000 fiesta vee 270. hah!
Go Steelers!!!
opppps gotta go my wife says i cant play anymore.
ALL sources on various sites on the net say it does. Why is my mechanic saying it doesn't and why would two different merc customer service reps say it doesn't. I don't get it.
Here are the part numbers right off my invoice:
1. Engine - part # 8M0109404 @ 11,650

2. Risers - part # 864929A2 @ $600.00
http://www.mercruiserparts.com/864929a2-kit-3-riser
More specifically, here is what I think (not 100%sure) a FWC 383 looks like, I don't see where the 3 inch riser goes that isn't already included.

If this is a direct order from Merc, that's too bad, looks like the thing wont be there till next Wed and if I'm being charged 25 hours of labor there's no way it'll be in the water for the long weekend.
