The First Two 336 Models
 

My investigations reveal:-
336 prototype, N34273, c/n 633, F/F February 28, 1961, was
fitted with two x Continental GO-300-C of 175HP.

336 prototype, N........, c/n 636, F/F August .. , 1962, was
fitted with two x Continental IO-360-A of 195HP.

336 production models with c/n 336-001 on, were fitted with
two x Continental IO-360-C/D of 210HP.

Can anybody confirm that this info is correct?

Registration and First Flight exact date required for the second prototype.

Any additional info welcome.

Alll 336s were produced with the IO-360A rated at 210hp for 5 minutes and 195hp max continuous power .

336 engines
 

Were we ever able to resolve the issue of which engines were in the 336? Was it the A or the C/D? As I recall, they all had the A engine but I'm not at all certain of that.

I believe davidh's response was correct. IO-360A, 210HP for 5 min, 195 HP max continuous.

Though I've misplaced my copy, if I recall correctly, that is what is in Scott Smith's book as well.

Dear Sirs,
As a proud "SKYMASTER" (Not Super Skymaster) I offer my input.
Yes the first Skymaster was powered by the smaller continental GO300 enines rated at 175 HP for takeoff (same as used on the Cessna 175 variant of the 172). This was also only a four seat aircraft with minimal baggage space.
On speaking with prospective clients Cessna decidied to go ahead with a major redesign to include the Continental IO-360A engines(and only the A model, unless you have an STC!) and a larger cabin for up to 6 persons.
There never was a prototype of the larger model with Cessna simply producing Serial number 336-001, N1701Z, in late 1962 for sale in early 1963.
A variety of options were available including full pnematic deice boots, stretcher set ups, camera ports, tundra tires etc.
The rear cooloing fan is of course a rather obvious difference to the later 337's. However the 336 and 337 do not even share the same type certicate, and have almost no interchangeable parts.
The greatest change that occured with the first 337 was the addition of a higher wing incidence (I believe 5 degrees) which did a nice job of reducing the very nose high flight characteristics of the 336. This can be greatly reduced with a Horton STOL Kit.
Anyway, just my thoughts.

N3804U, still going...
 

After all these years could She still going! Thinking back the year was 1964 yes 1964 and I just dug out my old log book. I remember the new airplane on the flight line a Cessna 336. If I remember correctly it was owned by a colorful gent by the name of Willie Palmer. I was working at the FBO in Portland Maine as a charter/instructor pilot. The entry in my log book is 7/23/64, :45 minutes dual. Wonder how many times I crossed paths with Her over the years flying for good old Delta Airlines from 1966 thru 1996... Think I will look Her up! guy, the old DC9/727 driver...

(looks like they may be using Her as a spray airplane!) guy.

Dear Sirs,
N3800U is indeed based at Brookley Field, Mobile AL (KBFM) and is owned by some branch of the local government.
The last time I saw her on the flight line was in 2000. At this time she was outfitted with an ultra low volume spray system for mosquito control. Speaking with the pilots she was not seeing a lot of use, but appeard to be in good flying condition.
I am at KBFM perhaps every month and have not seen her since.
It is just good to know that a few still are in hiding to be saved for the future.
Regards
