[OMC-Boats] Replacement Alternator

Took my Prestolite ALK-5206 alternator to a local alternator shop for a test.  They advised it was heavily corroded inside and not repairable due to it's age.  Hmmmmmm.....Really?  Anyway, they looked up a replacement advising $322.00 with tax.  OUCH!   If I order by 2p they could have it tomorrow.
 
I did a google search.  Go2Marine sells a NEW API alternator for $210 with shipping
http://www.go2marine.com/product.do?no=76823F%a0.%a0 The downside is I wouldn't get it till next week.  $100 saved is $100 spent elsewhere and it bugs me to miss another weekend. 
 
Of course I could always get a longer oar for only $35-50.00.......

3)  As far as your Prestolite Alternator:  These come up on ebay once in awhile. If you find one at a reasonable price, you can practice rebuilding it yourself and you'll have spare. The are fairly simple and easy to work on. If you search the internet under ALK-6207 or OMC 383443  you will find many of the parts are still available (including the solid-state regulator) for this alternator thru BRP/OMC dealers, amazingly.  One nifty feature of this Prestolite-OMC design is the external regulator is essentially water-cooled, by heat sinking the regulator to the thermostat housing.  With an internally regulated alternator the solid-state electronics are exposed to higher operating temps which can get quite high. especially if the alternator is operated under heavier than normal duty cycles.   Just remember to have your ALK regulator checked out along with your ALK alternator. The regulators rarely failed unless someone as incorrectly re-wired or
 abused the system with a 2nd battery and switched the alternator under load.
