I have a 5.7L (350ci) Mercruiser with what I think is a frozen steering cable. I am attempting to remove the cable , but the radiator reservoir and heat exchanger are mounted on the rear of the engine right above the clevis pin on the end of the cable with not enough room to lift the clevis pin out. My first instinct is to pull the heat exchanger, but that would involve removing the u-bolts holding it in place (hard to get at) and disconnecting the hoses on the underside (REALLY hard to get at).......Any other ideas would be appreciated.
