1996 ShuttleCraft 15? ? turn PWC into ?Jet Boat

Slide your PWC into the ShuttleCraft that turns your PWC into a jet boat. See www.shuttlecraft.com for more information.
I bought this used late last fall and put the following into it last summer: Rail kit for wider/newer SeaDoos (I have a 2004 GTX), new battery, marine radio/cd/mp3 plug, new speakers, master battery switch, battery tender (to charge without removing battery), and bilge pump.
All work done by local marine shop. Fiberglas in great shape ? no holes, scratches (a few small spider cracks around the cleat area). Interior was in great shape until we power washed it ? and created a few tears.
The plan was to use it for a year, and have everything redone - from gelcoat to new vinyl. ShuttleCrafts also feature running lights (use at night), large storage compartments, and cup holders. Over $4,500 invested ? must sell ? too many toys. $1,500/reasonable offer.
