That is a cool web site but the only reason I can see to restore a GT150 is to make it as "much ilke" the original Bond as possible. It's never gonna be a great perfomer, there are a lot better 15 footers out there. However, the boat does look cool. I wouldn't waste the money on a new ETec specifically for this boat, besides it would be a little to heavy. It would be easy to find either an original 135 cross flow V-4 or any "bubble back" V4 and convert it to a 135. I'd look for an original Glastron runabout steering wheel, shouldn't be too hard to find.
