    The Numbers and letters stamped on the fly wheel are not original, the P 35 carburetor was used on the P 35, P 40, P 40, P 45 . Since it doesn’t have an underwater exhaust it’s not a P 45, can you get me the casting number of the cylinders and a better picture of the motor including where the gearcase connects to the lower tower ? Most likely it’s a P 35 or P 40 but if you’re lucky it may be a PR 40 which is more desirable. I’ll let you know more when you post the cylinder casting numbers ….Randy in Tampa 😎

    The only numbers I can find on the motor are these on the powerhead H 10 and H172 plus where the powerhead connects to the shaft 8628 and maybe a 4 but could be just a gouge in the metal. The transom clamp says P 8 on one side and H 7 on the other. I have sent a picture may be the wrong one. ( camera acting up )

    The cylinder casting numbers are located behind the muffler,Should be a number like H145, H146 etc ….. if I get a chance tomorrow take pictures of one of mine to show you 😎

    Randy, I pulled the gas tank and lo and behold from the back left jug H146 and right H145 . The motor seems to be all there except tiller handle , welsh water plug end of cyl and horn or something on the end of carb. Was this a South Bend motor ? The man that gave it to me said it was used to run whiskey across the Detriot river ( good story )

    A Lincoln Head Penny will make a nice substitute for the water jacket plug. Find a nice old one.

    I like the Whiskey story!

    The carburetors originally came with the air horn they’re extremely hard to find, don’t remember where they’re made soon as I get home I’ll look at mine and let you know

    I can’t help you with the casting numbers,but if the number stamped on the crankcase flange is read as 86284,it would be a 1928 motor crankcase.That would make it a P40,I believe,and likely a South Bend motor.According to my parts book the P35 and P45 had different carbs.The P35 carb is shown with P35 cast on the carb.Also the list shows the P40 having a release charger,but that might have just been the later ones.That’s all I got.

    The P 35 cylinders are unique to the motor, the P 40 and the early PR 40 are bushing motors, The later PR 40 and P 45 or roller bearing motors and have higher compression due to the cylinder heads being padded inside and the timing is different, it’s my understanding that they all use the same carburetor but I could be wrong again all mine my P 35, 3) P40s , and 3) PR 40s all have the same “P35” carburetor i’m not sure if there’s any differences , as for my 2) P 30s have a different carburetor, I do not own a P 45… Yet. Needless to say they are all cool motors and not common, get it running and enjoy it and then pass it on to someone else who will enjoy it …. as far as the compression relief goes I believe it came out in 1929 I have a PR with a compression release cylinder not sure if they came standard on the P 40 but I heard it was an available upgrade 🤔

    Thanks for the info I still not sure by your comments if it is a P35 or P40. the H146 and H145 casting numbers are they unique to the P35 ? the 86284 serial number would make it a P40 1928 back out to recheck serial numbers.

    My two P35s just have H1 and H2 as casting marks on cylinders.I think it’s a P40.

    During Prohibition Rum Running was a lucrative and dangerous business. The purple Gang, the Mofia and the FDA were in constant battle with one another. When we first moved to Detroit, we lived across the street from Fox Creek which routed Detroits treated sewage into the Detroit river. Mom was nervous when Dad was away seeing his Evinrude dealers and kept a pistol under her pillow. (Until the day she found me playing with it) One evening while checking house security while getting ready for bed, she saw some men seemingly hiding in bushes across the street. She immediately called the police who sent couple squad cars. It turned out this foiled a sting operation by the FDA to arrest some rum runners who saw the commotion and turned tail and got away. Mom was commended by the Police for doing her civic duty, but Elliot Ness’s Detroit compatriot was not pleased . . .
