This Pro-Pull chain puller (rammount.com) is similar to the Walter, but chains connecting the two plates weave between overlapping propeller blades. The plate between the shaft and strut fits up to 2 1/2-inch shafts. For larger shafts, chains hook around propeller blades with hooks (shown here tie-wrapped to chain ends for storage).
Hydraulic propeller pullers are typically a variant of chain puller.
