I pulled my merc 165HP 4 cyl. It looks like a clean engine and already has the upgraded 4 inch cooling system. I cant decide if i want to go thru this one or buy the inline 6 from this man who says i can have the engine with about 100 hours on rebuild, the outdrive and all accessories for $800, located about 120 miles from me, or buy this donor boat with the 4.3 liter with everything for $2100 and i could put this motor in that boat and sell it! Open for suggestions. P.S. My boat is a 1987 21 ft. SeaRay Seville with cuddy cabin in excellent shape. How do i attach pictures?
