Re: cheap sailor, inboard vs outboard
This is a common dilemna for those with older boats and inboards that are becoming questionable.. in most cases the cost of repowering is much more than the value of the boat, and the 'new repowered' boat will never be worth it's residual value PLUS the new engine's value... at best you'll probably sell the repowered boat sooner than a similarly priced boat with the original engine..
So... what to do? Slap a bracket on the transom and hang an outboard as you've suggested (you might try a search here on the subject)..
Two major issues.... the prop is now behind the boat rather than under it.. you'll need at least a long shaft version, probably an extra long shaft (25") and even so in big chop the prop might come out of the water with alarming frequency.. losing drive when you need it most. The other issue is aesthetic.. nothing ruins the lines of an attractive boat like an outboard hanging off the back. On the plus side you can take it home to work on it.
With the Vega specifically it looks like you have a rather high cockpit coaming aft, and as a tiller steered boat reaching the O/B from the helm will be a problem.. you can add shift and throttle controls, of course, but you'll lose maneuverability because the rudder can no longer redirect the propwash. You can regain/enhance maneuverability by 'steering' the outboard, but that will be awkward to do. Another issue here is that if you have the motor swivel loose enough to steer, torque and vibration often cause the motor to drive itself off-center and you're constantly having to correct that.
It's not an ideal solution, but for obvious reasons it's often done.
