This is a good powerhead, complete with pistons, crankshaft, connecting rods, bolts, and so forth (as pictured). Please note that this will need a new base gasket and spark plugs installed prior to use.

The motor had a burnt wire on the idle speed control assembly, part number: 87076A4. but still had good spark. The wire could more then likely be fixed and will be included with it. One of the switchboxes has been replaced with a aftermarket replacement. The studs have been removed for shipping puproses but are included. The starter runs good without any whining noises. This is a full dressed powerhead and should be ready to mount and run short of the idle speed control assembly. The carburetors are stamped with WMK-41. We would recommend rebuilding them prior to use. This will come exactly as pictured and will make a great replacement!
