Re: How much does a 1970's 70 hp Chrysler weigh?
I would first take off the hood so it doesn't break if the engine gets away from you. Then I would back up the truck, with the tailgate down, real close to the boat at 90 degrees to the transom and a few inches away from the engine leg, After loosening everything holding the engine on, the two of you should lift it off the transom and let it slide under control, down onto the tailgate until it is resting on the "support plate" on the edge of the tailgate. This is the pan shaped plate that the hood sits on. next, grab the lower unit, lift, (which, depending on the height of your truck may be resting on the ground) and just roll it into the truck and slide it forward into the bed. If the steering goes through the clamps, you may need to slide the engine sideways to remove the steering cable so leave room for that. Use a blanket or two or even a small sheet of plywood--big cardboard boxes etc. so you don't scratch the tailgate. A few ropes wrapped around the block make it easier to handle. With two people, (One standing in the truck and one on the ground) it's a piece of cake.
The engine clamps are bolted through the transom so you will need two 9/16 wrenches, and one person in the boat and one outside. In the well they will be either tightened by hand screws or a 9/16 hex screw. Steering--depends --maybe 9/16, maybe 1/2. Flat screwdriver to remove control harness wire. Depending on how the control box is mounted to the boat, you may need only a screwdriver or, you may need a screwdriver and several smaller wrenches if it is nutted in the back. Ignition Switch will require either 7/8 or 15/16 wrench or a big adjustable. Control cables are connected to the engine by quick connect fittings. no tools necessary. Starting cables 1/2 or 9/16 depending on solenoid nut and ground bolt. Fuel line may be held on with a wire clamp needing a pliers to remove , or a screw clamp. It should take about 15 min to 1/2 hour to remove everything and get the engine ready to dismount.
