Hello Hans,
If it comes down to picking between "store bought" inboard vs. outboard electrics keep in mind that, whichever you choose, working out a safe and secure battery installation will likely be the biggest part of the job.
The cost of an inboard kit vs. a serious outboard such as the 48V Torqeedo (I don't think you'd be happy with anything smaller on that boat) are in the same ball park.
If you already have the prop, shaft, stuffing box, etc. from the old inboard installation, an electric inboard installation is very straightforward and can be easily accomplished in a weekend if you buy one of the "plug and play" kits on the market. (OK, full disclosure... my brother owns Electric Yacht but I have no financial interest and am not here to plug his products)
If you don't have the prop and shaft and all that, it's a little more complicated but still pretty straight-forward.
I'm in the middle of installing a electric inboard into an Albin 25 trawler that had the original diesel removed by a previous owner in favor of an outboard. The only thing left was the shaft tube, which was plugged at the outer end with bondo. A used prop and stuffing box, new shaft, and new cutlass bearing came to about $500. About 2/3rds of that was for the new custom shaft.
Whichever way you go, there is plenty of collective experience to draw from on this group.
Good luck.

PS.
A word on minimizing prop drag, with an electric drive you can neutralize prop drag entirely by dialing in a tiny amount of power while sailing. Also very helpful in light air where just a little bit of thrust can help you through the lulls and create just enough apparent wind to keep the sails from slatting.

> >New to the group. I live in Florida near Tampa.  I have a Irwin 28 sailboat. The gas engine was previously removed and has a 9.8 Nissan hanging off the back. I've been interested in changing to electric but have been having a hard time finding a cost effective means to do so. In searching the internet I found this group, so here I am. I'm handy with tools and can build/assemble what is needed, just not sure exactly what is needed. My intitial plan was to strip the bottom of everything associated with the old shaft and fill in the stuffing box hole. I wanted to use a large electric trolling motor that could handle a large prop so that I could remove it when not in use and store it in a cockpit locker. My assumption was that I could get rid of the drag underneath to help this old boat to move in lite winds. On the otherhand, I'm not sure if it would be just as easy to put the motor inside. I am also looking for electric regeneration
> possibilities when sailing to charge the batteries from the motor being used as a generator. I have yet to find information if trolling motors can do this. Thanks for any advice. I have yet to dig thru the archives for any information yet.
