300/440/550 550PP or 550 Reeed Crank any difference?

[EightySeven550]

Hello all,
Is there any difference in the crank for a 550piston port or a 550 reed motor?

Thanks all,
Andre

The piston port cranks had replaceable rod pins and the reed cranks were not. But the cranks are interchangeable.

cranks are identical from 1986 until 1994.
the 3 piece cranks elmol refers to were used on early 550 and all 440 iirc but they would still work on your boat.
only very early 440 and 400 cranks with the double rear bearings will not work
