well i know i want to fix er' up, i have done a lot of reading and the A4's seem to be good motors... BUT only if you have a GOOD working bilge blower. the A4 that i have has rust on it nothing to bad or thick, so i will ospho (this acid we use on the schooners) to clean the rust off after chipping as much off as you can, you sand it, then ospho, then wash with water, then prime/paint! i will have to re paint the whole thing. replace all spark plugs, rebuild carb, change oil, put in inline fuel filter, change oil filter(s) and flush the thing with fresh water. replace any fuel and water lines needed. new prop? this place has a new 3 blade prop for the A4 that sounds great and is $310 not to bad, but for now i will use the old prop. it seems easy to find parts for the A4??!
