Rich, you are not going to be able to do it yourself anymore, call Ed's and ask how much you can do yourself to save a buck (tell him you are on a budget), the rules changed since I did it. And Bombardier ETEC never let me do it myself at all (cash and carry), same for Suzie, I did inquire back in 2005.
The dealer has to hang the motors, connect them, fire them up in water. I think. Even Ed's. In other words, you can't dirve your pickup into Ed's and have them load new motor(s) into the bed and drive off. Last time I checked, but that's how it used to be.
You will be able to strip old engines and controls, and perhaps even mount the new controls and pull the elec and mech cables, fuel, that's it.
How much they charge for what's left vs. how much you save I don't know. Dealer wanted about $1.5K per motor labor for the entire job.
So you may still save if they let you do a % of the work yourself.
Some dealers work with DIYers, some avoid them like the plague.
After I finished my job complete and even ran them in driveway, I did want to bring boat into dealer to have him go over everything (even though I didn't have to - already had the warranty cards), but he didn't care to mention a price and scope for this work after I called to schedule a visit in teh Spring. I was willing to pay but didn't like to go in without a firm price if you know what I mean.
So I didn't.
;' sit.
