Re: Please explain differences in correct/incorrect Chrysler 35/55 series.
Well, models numbers would tell you but I don't have them and never really paid attention to them.
The 20, 25, 35 series engines were single carb two cylinder engines with about a 1/2 inch drive shaft. Prop was 9 inches diameter with an 11 spline shaft and a pin drive.
the 35. 45. 55 series engines were also single carb, two cylinder engines. The drive shaft was about 9/16 diameter. Props were 10 3/8 inch with a 13 spline shaft and pin drive.
The 55, 60, 65 engine series as far as I know, were never made in short shaft versions--that is, I have never seen one--But I certainly have not seen them all. They were twin carb two cylinder engines with a 5/8 inch drive shaft. Props were , in the early units, the same as the 10 inch props for the 35, 45, 55 and later units had a closed hub 15 spline prop with a thrust washer Just like the later larger Force engines.
So: Ask what size the prop was and most likely you will get the correct shaft.
Hope that helps some.
