I have a rebuilt gimbal housing including rams from a 140 hp alpha 1 mercruiser. I bought the whole outdrive from fishers of men from a boat he was parting out for a friend. I only needed the lower unit. The lower unit was fit right on my motor and was in excellent condition. Has run with no problem. everything appears to be in the same shape on the housing. did not pressure test the rams, but as I say unit was rebuilt. asking $250.
