Universal 5416 marine 20hp Diesel and transmission.  Year is unknown. Have had the unit for almost 20 years. Supposedly ran when I obtained it in a trade for partial payment for services.

Local pick up only, No shipping, but delivery within a 100 mile radius is possible for $300.00.Unit is listed locally in Miami.Thanks.
