1998 Mercrusier for Alpha stern by Mercury Marine! Looking for a working engine on the cheap, or a salvage engine for parts, don't miss this offer. This engine is in working order and was running when it was removed for a re-power of my boat. Here are the specs: 2 barrel 5.7 Liter 350 cu in 210 HP Disclaimer: This engine had salt water intrusion. The root cause appears to have been rotten exhaust flappers that allowed water back into the engine from the exhaust. Water was pumped out and the engine started right up. Sold as is minus riser blocks.
