    I am considering buying a 1985 sea ray 390 express cruiser. It will need two new diesel engines. I'm wondering what engines will fit in it and work and what engines are recommended. Any information will help. Thank you.

    I would think, if it needs 2 diesel engines, let alone anything else. The boat should be free.

    Low price. I'm trying to see if it can be done - and should be done.

    There is a great group of 390 owners on here. Several have done major restorations. FrankW owned one for many years and knows them inside and out.
    Listen to what they say. They know what they are doing as regards to the 390. Search for the old 390 forum thread. Thats is a good place to start. Good luck. JC

    390EC's are great boats, but you picked an early year that tends to have problems with rotting seat bases, rotting cockpit side walls and wet stringer due to improperly sealer limber holes. Add to that the cost of 2 fresh or used 3208 Caterpillar engines and you can probably find a decent 1989 for what you would have invested in making a 1985 model seaworthy and safe. The 1989 and 1990 models have fiberglass seat bases and resin sealed limber holes.
