Parts Problems - Volvo

[MASATS]

I need a few opinions and information if you will.

I have a project Avon 7.4m which has a Volvo 200hp diesel I/O with a jack shaft. The engine runs good. I cannot get the parts for the out drive or the steering. The jack shaft I can have made locally. I see three options I would like comments on.

Replace the old out drive with a new unit, which would require hull modifications.

Buy a transmission, shaft and underwater running gear and make her an inboard. Plug the transom hole.

Buy a pair of outboards, sell the diesel, plug the transom hole and put a bracket on. Would a pair of 115hp 4 strokes be enough?

Anyone that would like to weigh in I would appreciate your insight and experiences.
