The early small K Models on back burner for moment.
Attended an outboard club meet Saturday. A fellow I did a favor for gifted me with a Mercury KF7...well not exactly...items had been removed and it looked like a salty but was assured its condition was from being left in a wet boat house for many years.
Separated tower from powerhead. Tower looked promising after cleaning and rolling over prop shaft.
The powerhead was another matter. I noticed the Champion spark plugs were J7
and J11 which raised suspicion motor had been ill before it was hung up.
When flywheel came off I noticed half the ignition had been removed prior
to many years of corrosion. Another sign motor had problems that took it out of service and were not repaired. At the moment powerhead is mostly stripped down
except for exhaust cover which was left alone because 3 screws were stuck.

New to me technique: used Dremel tool with abrasive cutoff discs to cut long
slot in key that could not be removed by other means. The slot was not deep
enough to go thru key into keyway so no harm done to crankshaft. Stuck key
was then driven out with nail set used as punch and small ball peen hammer.

Although I intend to complete tear down of powerhead it is likely as bad
inside as it looks outside. I am awaiting a friend to return from "Up North"
to advise and assist as the larger Mercs are more his flavor than mine.

I have been looking into subject of straightening crankshafts. Not sure if
it is something I can handle. A set of V Blocks needed to test and determine
high spot of run out.
