I have an 18' Signa Runnabout (1974) that I would like to convert to an outboard motor. It was originally set up for inboard. Anyone out there have any experience in this sort of thing? I've never done anything like this before and I would need to know the process pretty much from the basics.
Thanks,
Paul

I converted a 18footer inboard with a 135 omc to a 200 hp mercury outboard. I found no problems doing so, just use common sense.
1. I removed the engine, and stern drive.
2. I filled in that large hole, while plywood, then fiberglass filler, then fibercloth, sanding, then paint. on the outside I put 1/4inch stainless steel plate across the whole rear end. On the inside, I also put 1/4 inch plain steel inside, thus I used stainless steel bolts,washers, and nuts, mostly in the 1/2inch range.
3. The hardest part was re-treading 1/2bolts for my use, this took a air-torgue wrench like for removing nuts off of studs from a car tire and a heavy duty vice. I also cracked two treaders because of the force and the number of bolts I did around 40 of them. The boat does not leak, the boat goes like a bat out of hell, my new transom, is a jack plate made in flordia. good luck, and it was fun doing the boat. joe stachyra
