Hi,
I have two Johnsons, a FD 18hp and a QD 10 hp both MY 1960 in my basement, the first with a stuck and corroded PH, the second with a cracked gearcase.

My winter project would be to join the good parts and create a Franky 10 hp "bigfoot" (using some QD 1957 parts), equipped with the original ’60 plastic upper cover.

I bougth all the needed 1957 throttle and gearshift linkages, so mechanically the project can work, but unfortunately I discovered the 18 hp front handle is different shaped and the QD lower cover cannot fit.

My "B" solution is now to swap also the front handles /cover mount plates (The "C" plan will be to make a custom "shell" cover :rolleyes: )

Before I disassembly all the legs unnecessarily, does anyone know if the QD handle can fit on the FD steering/exhaust housing?

QD steering handle, or the tiller handle? The tiller handles are the same, but the steering handles are different….
Kind of confused with your explanation….I would guess that the QD powerhead will fit on the 1960 midsection without much modification, you may need to change some of the brackets that the vertical throttle rod is on…
Again, I’m guessing that the shift detent rod will fit properly on the FD midsection, seeing that the earlier QDs were on this midsection, but don’t know that for sure…
Again, I am assuming both these engines are 1960 vintage with the fiberglass hood. If not, then all bets are off due to the powerhead mounts for the older aluminum hood….
Post some pictures if that will help….Don’t know why you needed to buy 1957 linkages, but I’m guessing I am not understanding the swap completely…

I am not understanding either! I don’t think anything will fit using these two motors. The 18 has the five bolt lower unit the ten has the four bolt. Hood physical size is different. Better find another ten or 18 to do your swapping!

Guy,
You are fighting a easy swap, Find another powerhead of the same or close match or what ever is broken.

Well, the QD powerhead "should" actually fit onto the FD midsection, because 55-57 QDs were just that, the smaller powerhead on the larger midsection. So, I’m thinking the later QD powerhead should bolt up to the FD midsection and be able to use its larger gearcase….
The difficulties stem from trying to use the newer style powerhead (fiberglass cover) on the older style midsection that had the clamshell hood and relied on cover mounts found on the head and intake manifold.
Needless to say, there is no guarantees here, but I would be pretty confident it will work out…
But, again, I’m not quite sure I understand what Enrico is asking, and am hoping he will post some pictures…

Well.
It is not easy for me to o explain in English, but I hope the photos will help.

FIRST: I know it would not be a problem to find a FD spare PW … Very hard is to find a QD gearcase here in Italy… but my real target is to create something new…

I found no problem to fit the QD PW to the FD leg without the lower cover. The pattern is essentially the same, only for the QD front stud I need to use a bolt/nut assembly.

No problem also for gear lever and gas. Just I used the linkages from a 1957 QD.

So when "naked", the engine could work.

Also the drill pattern of dampers in the lower cover is the same, so potentially I can swap the covers.

The problem is that the FD’s dampers front mounting plate is wedged instead of plane as in the QD, and the QD lower do not fit correctly on the flange on the upper leg. In this way, the base of the carburetor tap the lower cover and the PW does not fit correctly.

I would like to use the QD mounting plate, but to do this I have to swap the front handles as well.

My question is whether anyone knows if it is possible or the dampers or pivot rod mounting points are too different.

OK, I think I understand what you are referring to….
Can you use the original FD pan and engine cover? If not, I’m thinking that bracket will have to be changed which means the powerhead must come back off. But, I’m not sure that the QD support will bolt up to the FD midsection….
What do mean by: PW?
What handle do you have to change if you use the QD bracket, the steering handle? Are you saying the lower cover will hit the steering handle if you use the QD bracket support? I don’t know if the QD steering handle from the smaller midsection will bolt up to the FD midsection…
In any event, seems like you will have to remove the powerhead no matter what changes you make…
Very interesting project for sure! I’m sorry that I did not consider that bracket when I assssumed the powerheads could be swapped out…
Again, could you use the original FD pan and cover with the smaller QD powerhead in place???
Please let me know if I am not understanding your problem, thanks for the pictures…
I am thinking you are referring to item 108 in this diagram:

Hi, Fleetwin.

I checked and the QD part [108] ( pan mounting bracket ) bolts up on the FD leg, but collide against the FD [78] handle, and is this part [78] I would swap…

That makes sense . . . 😀

Never tilt the motor by pushing down on the tiller.

Cool, so you can just use the steering handle and lower cover mount bracket and you will be all set, correct??
