This is a powerhead from an early 1990's Mercury 25hp outboard motor. Never saw the motor run as it was low on compression when I bought it. This powerhead is complete, but will need new rings and rebuilt. No holes in the block and very clean. This is from a part-out so check out my other listings as I do combine shipping. This is a 7-day no-reserve auction. Buyer to pay shipping. Message me with any questions.
