I know a marina that is doing a repower. I took a pair of 454's out. one is counter rotating, compression is decent motors have about 2000 hours. they are complete with clutches. I think the clutches are 72 seriers velvet drives with a 1.98 ratio. motors can be had for a decent price. I think the guy is asking 5K for the pair.may golower. I did see ATF in the bilge so I suspect at least one of the cluches may leak or when he replaced the port trans oil cooler the fitting is not tight.I think they are 1990 motors.<br /> but they are full fresh water cooled and the risers were replaced a few years back and still look ok from the outside.
