Installation Flexibility

Purpose designed for marine use, all standard version PRM gearboxes have output shafts vertically offset from the crankshaft centre-line. However to cater for the installation demands of the widest range of hulls, both the PRM260 and PRM750 are available with an in-line configuration, while down angle options are offered on the PRM750 (8deg) and PRM1000 (10deg), excluding the 4-1 ratio versions.

PRM80, PRM120 and PRM150 units are suitable for use with left-hand (anti-clockwise at flywheel) rotating engines only. In standard form, all other PRM gearboxes are built for use with left-hand rotating engines, but can be converted simply to accommodate right-hand (clockwise) rotation engines by turning the oil pump through 180deg.
