One option you have is to sell it locally. If it's in good shape you should be able to get $1000 for it...always someone looking for an early bolt on replacement.

Trouble in the Drink
 

I'm not really sure where to start. I have a 1988 Scarab Excel 28 with a Bravo 1. Took the boat in to have it looked at after some problems. The seals in my lower unit were shot and I ended up with a nice water oil mix. I'm not sure whether to sell the boat as is or fix the problem.
