4JH5E propeller questions
What size propeller suits a Yanmar 4JH5E?
It depends on the gearbox ratio behind it (documented installations most often run 2.32:1, 2.49:1, 2.23:1) 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 Yanmar 4JH5E owners fit?
Documented Yanmar 4JH5E installations run Autoprop H5, Varifold 3-blade, Autoprop H6 — the split follows boat type and usage rather than the engine itself.
Does the Yanmar 4JH5E come in shaft and saildrive versions?
Both are documented: 30 shaft and 52 saildrive installations. The propeller differs (hub vs spline fitting) so tell us which yours is.
Running a Yanmar 4JH5E?
Two minutes in the Builder — engine pre-filled, gearbox ratio checked against the fleet, verified by an engineer within one business day.
