On the spec page, the 4825DF engine shows a bore of .85 and stroke of .8 and the size is .48. If you do the math with the listed numbers the size works out to be .45. So is the engine a .45 or is the numbers wrong on the spec page? If the bore was a .875 and the stroke stayed the same then the engine would be a .48. Also I am wanting to build an outbourd using the .48 piston and sleve if it is a true .48 size. My next question is will it fit the Pro outboard case?
Thanks,
Bud
