This powerhead does run but the #1 and #5 cylinders had poor compression and leakage numbers.

Compression Test:
90/125/125/125/90/130

Leakage Test:
22%/8%/10%/6%/18%/5%

This powerhead is clean!  It is from fresh water use and it is not corroded and there are no cracks in the cylinder block.

Here is a video we have of the engine running in January 2023.



You will receive this exact powerhead you see with everything pictured.

This ships on a Freight Truck so you will need to be there for delivery. Commercial address is best for this type of shipment. We will contact you after the sale to confirm the address and phone number for freight truck delivery.
