Default twin vs single outboard

Hey guys,
My v20 came with a 140 evinrude bubbleback that needs a rebuild(Scored piston). I have a extra powerhead already bored 030 over and I was going to hone and deglaze the cylinders and give it new rings. I have all the parts and was going to rebuild it and put it back on..before a craigslist ad caught my eye for 2 85hp Mercury i4 outboards, both running, for 600$. While I love the thought of having twins, I THINK that...
a) I'm not sure the transom would appreciate the extra weight
b) Fuel economy would probably be much worse than with a single 140 or 150.

Trying to talk myself out of the idea before I end up with more un-used outboards sitting in the garage..

thoughts?
thanks
MJK

I would (if I could) rebuilt the rude and use the money you saved for that IPOD ready stereo.

I think I'll be sticking with the rude. I also called the seller and it didn't seem like they were in good condition anyway..

bought a nice pioneer ipod/mp3 ready receiver and set of clarion marine speakers yesterday

"2 85hp Mercury i4 outboards, both running, for 600$" sounded a bit "too good to be true" for decent motors.

Hope you get your boat running soon and that your stereo sounds good!

Me too..the boat was in surprisingly good condition for what I paid for it. Stringers, floor, and transom are solid!! The cuddy was a mess..the PO screwed 1x4s down as a sort of floor and the thick wool carpet on the sides will be coming off too.
Because I'm paranoid about old or improper wiring (longg ago boat fire...good story ) re-wiring everything, dual battery switch with charge isolator, fuse panel, etc. One 2,000gph pump(overkill, maybe!) for the aft bilge and one 800gph for forward of the gas tank, just in case. Andd bought Red LEDs for deck lighting from ScarabChris at thehulltruth.
I've been working on the engine whenever I'm home, last weekend I rebuilt carbs, fuel pump, new brushes on the starter, and cleaned up the heads, and re-painted the engine cover and decorated with OEM decals from Nanas on ebay. New piston, rings, water pump, and thermostat are next.

Aside, any idea what kind of fuel economy I should expect from the 140? WOT is probably around 14-15gph hopefully less cruising..
