Hi Keith,
The parts I mentioned, you can get at
www.offshoreelectrics.com (among others) mail Steven Vaccaro and tell him what you have in mind, he's a nice guy and will advice you on what to get. (then you'll know what I mean, regarding "setting you back...")
Basically one 700 motor is enough, though there are people who have crammed two in this hull, resulting in a very heavy, overpowered boat that is hardly drivable, there's info and video's on the single and twin 700 version, do a search.
Rooski is right on the hull, it needs reinforcing, once it's cleaned out, either by ABS sheeting, or glasscloth and epoxy resin.
It's quite a bit of work, but you'll end up with a very quick boat.
Regards, Jan.
