4108 propeller questions
What size propeller suits a Perkins 4108?
It depends on the gearbox ratio behind it (documented installations most often run 2.14:1, 2.74:1, 2:1) and the boat it pushes. Power and max RPM set the optimum diameter; the ratio converts engine speed to shaft speed. The Builder runs the numbers and an engineer verifies.
Which propeller family do Perkins 4108 owners fit?
Documented Perkins 4108 installations run Autoprop H5, Varifold 3-blade, Autoprop H6 — the split follows boat type and usage rather than the engine itself.
Does the Perkins 4108 come in shaft and saildrive versions?
Both are documented: 60 shaft and 1 saildrive installations. The propeller differs (hub vs spline fitting) so tell us which yours is.
