My alternator is no good so we are looking for replacements.
SkiDIM.com recommended this alt for $175

We think switching to a more comon (GM 10SI) alternation is better. Dad has a 10SI in the shop and the case appears to be a direct fit. There are many available on ebay that are marine/coast guard approved - lots of them in Mercury stern drives. this item number appears to be the best price ($60) with shipping of $12.00.
We are looking at this one:

We are also having an issue with our electronic ignition and may have to replace it. Inside the rotor is a cap with magnets. The sleeve that holds the magnets in came unglued and we are not getting spark on a few cylinders.
New electronic ignition is on sale at SkiDIM for $70

We sent Pertronix an email to see if we can get a new magnet sleeve - will need to wait for a reply.
