No disrespect, but my impression is that you don't want to learn how to keep these old engines running and instead want it all fixed and reliable as a kitchen appliance.

Without mindful preventive attention, you will continue to have problems - mostly minor and easily repairable. Most of us on this forum get a feeling of self-reliance and satisfaction from expanding our knowledge, heading off problems, and fixing issues.

I don't know about your aptitude, but your attitude seems incompatible with A4 ownership. Rather than continued resentment that these engines need care, I would suggest you get a boat with a new outboard for ease of service. Problems will still happen, but knowledgeable service will be easier to find.
