25" shaft vs. 30" ETEC on my 1978 23' CC

[EagleOCNJ]

I had an opportunity to get a sweet 2007 250 etec with under 200 hrs with an old boat thats not worth much. Its mounted as a single so i hoped it would be a 30 inch shaft, well it wasnt..... its a 25 on a bracket.

My seacraft has a raised transom and has twin 25" shafts. I intend to switch to a single and will need a 30" shaft. Do I have any options? I dont want to cut my transom back down, and a bracket job would be quite a task.

Is anyone familiar with the kits where you add the spacer and add to the driveshaft? They are between 600 and 800 plus Ill have to pay labor. Apparently the 250 etec has a 2 piece driveshaft, and the kit would make it a 3 piece, so the manufacturer reccommends installing a whole new one which may be costly.

I realize that Im kinda screwed on this but what are your thoughts.>>>
