I would add re-wiring the harness and any wires to the coil and engine.  Moyer 
sells a kit for that or you could just buy some marine cable.  I was having 
trouble with my engine stalling and not wanting to re-start for an hour at a 
time.  I really could identify with your stranded situations.  It turned out to 
be a bad wire...

You could really be out of this for far less than you think.  I know the 
feeling of just wanting it fixed.  I was at that point this year because of 
poor idling and blamed the A4 being an old technology.  I replaced the carb 
with a rebuilt I had done when I first bought the boat and before I bought the 
moyer and she run like never before.

It does seem like an electrical issue though.

Honestly, the Moyer swap would not cost $10,000.  The best thing about this old 
technology is how easy they are to work on.  If you take the initiative, remove 
the engine, then replace all hoses and filters and make sure the tank is clean 
or replaced while waiting for the new A4, the $ for $ investment would be very 
close between that and the outboard.  I've heard of people using their boom to 
hoist the engine up onto the dock.  I think these things weigh about 300 - 
350lbs.  Moyer will deliver to the marina and send you a crate to send the old 
one back.

The up side is you gain a huge amount of insights into your boat and engine and 
you would still be able to salvage September and October!!

Or, for far less but you could do the wiring and fuel system with the engine in 
place and see if it fixes the issue.  When the engine does run, does it run 
well?  If so, it isn't the engine, it is some support system, i.e. fuel or 
electrical, of the engine.

In the end you will be a better A4 mechanic than anyone you'll be able to find. 
 

You just don't want to throw the baby out with the bath water.

the 3 things an engine needs to run is good spark, Fuel and compression.  take 
those one step at a time, check the compression.  You can get a cheap 
compression tester from Harbor freight or the like.

http://www.harborfreight.com/catalogsearch/result?q=compression+tester

You can check spark the old fashioned way of pulling a spark plug and with the 
wire attached hold it near the block and crank.  This you may have to do again 
during an episode of not wanting to start.

I think you will need to replace the fuel system and clean the tank anyway if 
you were planning on feeding the out board fuel from the existing on board 
tank.  So this you should probably just do.  

Again, most of this is parts changing, out with the old in with the new and 
some peripheral vision during the process will help clean up some questionable 
issues along the way.  The problem with a "profession Marine Mechanic" that I 
have seen is, the cutting of corners and tunnel vision.  They just want to move 
on to the next project and call the current one done and don't tend to address 
adjacent problems while they are "in there."  I do far better work that anyone 
I have EVER hired to do work on my boat.  I have a very recent, long story 
about hiring professional that cost me 6 weeks of this season because they were 
sure they were right and I was wrong.  If they had done the job right over the 
winter and tested their work I'd have been sailing in May...

I think you should step back, take a breath, put your frustration aside, roll 
up you sleeves and re-wire that puppy and re-place all your fuel lines and 
filters and get that tank clean.

How do you get it back running after a non-starting episode?  I've heard about 
floating debris in the tank causing issues, blocking a passage during operation 
and then floating away after a while of non operation.  Or (as in my earlier 
case) as the systems heat up and expand, a faulty wire losing its, connection 
due to expansion and cooling and contraction repaired the conduit so it could 
start again until it warmed and expanded again...

If the block is OK and you have good compression and this hasn't been done
yet, I would get a price to upgrade to electric fuel pump, electronic
ignition, rebuild the carb (professionally), Install a good fuel filter /
separator and smaller in-line fuel filter downstream from the separator,
empty the fuel tank and change ALL fuel lines then refill with fresh treated
fuel. All that can be done with the motor in the boat. Take your time and
find a good mechanic that has experience with this motor. Can't imagine that
would be more than a couple $K. Certainly less than a refit to an outboard.
Just about any engine can be made to run reliably. Since the advent of
ethanol, fuel has become a persistent problem. Getting rid of the points
will remove the potential for a few problems, too.

Just a suggestion. Good luck!

Paul:

I hear you and feel you pain.  Been there.

Just don't underestimate the cost of the outboard route.  Even with a
combination of yard/DIY/Ebay I can't see this being less than a 4k project
and will easily top 6k yard alone.  That includes removing the A4, removing
all the associated systems and filling in some pretty big holes.  Beef up
the transom, buy an electric start outboard, a decent bracket and engine
controls.  None of this will add a dime of value to your boat. 

Electric is interesting but really doesn't like being away from dockside
power for more than a night.  That is likely an 8-10k project. as you still
need to remove many of the components and upgrade both your charging system
and batteries.

Repowering with diesel is going to be in the same range. at least

At the end of the day, I suspect the choice really comes down to a total
rebuild vs. time to sell.

Just an opinion.

John
