Re: 1978 Chrysler 65hp

Thanks Frank, I probably should have been a little clearer. From what I can see, the kingpin is attached to the lower cowling and the powerhead is attached to the lower cowling by only 2 nuts. I have already removed the lower leg mount and leg cover. It seems the the only thing stopping me from slipping the lower cowling with the kingpin and bracket attached, over the leg is the engine mounts and those few things that I listed earlier.

I will attach some pic later today, when I get home.

Cheers.

Re: 1978 Chrysler 65hp

let me see if I remember: The cowling is secured by a rubber gasket between the powerhead and the lower leg. I believe it is also secured by the two rubber bushings and nuts that you show in the photo. Depending upon the age of the engine, there may be a match plate between the engine and cowl or (on the early ones) the block may bolt directly to the lower leg with a sealing gasket. If it bolts directly to the leg, there are nine bolts under the lower leg that secure it to the powerhead. One bolt is hidden under the idle relief in the rear of the leg. There is the front motor mount that secures the powerhead to the cowling. The front motor mount obscures the top of the kingpin and must be removed to drive the pin out.

So, you are looking at a complete dismantle to free up the kingpin and swivel yoke.

Thanks Frank,

I will attempt it this weekend, will let you know how it goes.

Re: 1978 Chrysler 65hp

I just dismantled one today and if I were going to keep the engine , it would not have been fun. The kingpin was a press fit into the cowl with a nut on top. after removing the nut I needed to hammer with a 6 pounder to drive the kingpin out. I also needed to wedge a wood block behind the swivel yoke so the kingpin would clear the lower part of the midleg. Of course, the engine block was already removed. The midleg had a plate which held the cowl gasket and of course, the rubber isolators sheared. Thus, if I were repairing the engine I would have had a lot of work to do..

It doesn't usually work, but have you tried pumping a lot of grease into the swivel and heating it a bit? Not too much heat or you will melt the internal plastic bushings.

G'Day Frank,

I couldn't wait for the weekend, so being my own boss, i took half a day off and went for it.

I removed the starter, starter solenoid, choke solenoid and baffle, this gave me access to the front shock, after loosening that off and removing the top exhaust port, I was able to lift the complete powerhead and leg out off the swivel plate.

That done, I the moved to the king pin. This was tough! I ended up jamming a jimmy bar (crowbar) between the yoke and plate and while putting upward pressure on the bar, I hammered the kingpin up(no heat), I took a few good wacks, and it eventually freed up and was easily removed.

A good cleanup of the kingpin, bushes and port, some new grease and reassembled. Now it swivels with barely a breath.

Thanks again for all of your help, time to sit and drink some beer. It wasn't easy lifting the powerhead with leg attached out of the swivel plate while still attached to the transom (I'm 5'7", 70kg wringing wet) so I've worked up a bit of a thirst.

Glad it worked out for you. Hmmm! 70KG. That's about what I weigh--It doesn't matter about the size of the animal in a fight. It matters about the size of the fight in the animal. LOL
