This is a VERY slightly used SEI lower unit. It may have 25hours. It also will come with a S/S 19p prop. 8spline drive shaft 25 1/4 from housing to top of shaft approx. It will fit multiple models. I put the part number from SEI in the picture. Make sure it fits your motor as return shipping is expensive and if your not happy with the product I will return your money in full. Other than RETURN SHIPPING. 

Thanks
