This is a wonderful and hard to find engine. I have completely disassembled this engine and run the parts through an ultrasonic cleaner. The internal components are all in very good condition, pistons, cylinders, and lower gears are all in good condition with little wear. The outside could benefit from some light polishing but is still very nice with no major flaws. The engine turns smoothly and has moderate compression.The carburetor needle is the only missing component. If you intend to run this the internal gaskets could probably use replacement and the through bolt at the bottom of the crankcase will not tighten all the way, it is not a major problem and chasing the bottom hole with a tap should easily correct it.
Good engine, no hidden surprises. If you have any questions please contact me. The item "Vintage K&B Allyn Sea Fury Twin Model Outboard Motor Engine Nice" is in sale since Friday, October 16, 2020.
