Definitely get it looked at before deciding anything!!!! New motors are NOT CHEAP BY ANY MEANS!

Thinking of replacing my 140 looper on a 19'6 alumacraft...cheaper to buy another boat.  >10k for a decent 115 four stroke.

Yup.. buying a motor isn't always the best way to go. I had to laugh the other night.. I was looking at used boats on walleye central and I saw a ranger for sale. They wanted something crazy like 30k for it... WITH A BLOWN MOTOR!!!!!!  And I think it was a 06(if I remember right)

Sounds like a blown head gasket. Maybe a cracked head but my bet is the gasket. Do a compression test to verify.

Head was removed and revealed motor quite corroded prob due to salt water, unfixable.

I've had it happen in my 75 HP Yamaha 4 stroke the first couple years I had it.  I had this issue when fishing multiple times one early season in March when water temps were in the 30's.  My dealer said it was likely due to the cold water wasn't allowing the motor to warm up enough and they had known of it being an issue with outboards run in Greenland in extremely cold water.  I haven't had the problem ever since but it certainly had me concerned.  Your issue is probably something totally different but just thought I'd share my experience.

Good preventive maintenance is the purchase of "salt terminator". It won't prevent a blown gasket or cracked head under certain conditions but will
surely prevent corrosion and build up of salt on your internal parts, especially your thermostat. Buy the kit the first time around, it includes the attachment to go on the ears for flushing. My 60 four stroke Yamaha is 13 yrs old and looks and runs like new.
