4JH2E propeller questions
What size propeller suits a Yanmar 4JH2E?
It depends on the gearbox ratio behind it (documented installations most often run 2.62:1, 2.63:1, 2.14:1) 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 4JH2E owners fit?
Documented Yanmar 4JH2E installations run Autoprop H5, Autoprop H6, Varifold 3-blade — the split follows boat type and usage rather than the engine itself.
Does the Yanmar 4JH2E come in shaft and saildrive versions?
Both are documented: 79 shaft and 1 saildrive installations. The propeller differs (hub vs spline fitting) so tell us which yours is.
Running a Yanmar 4JH2E?
Two minutes in the Builder — engine pre-filled, gearbox ratio checked against the fleet, verified by an engineer within one business day.
