Correction!
RH is a "standard" rotation engine; prop rotates clockwise as viewed from the stern. The LH is an odd rotation usually one engine on powerboats with twin screws.
Also be aware that some transmissions will reverse the rotation of the shaft relative to the engine rotation; so you need to check either the driveshaft while the engine runs or the prop pitch to determine if the driveshaft is LH or RH.
My boat has a 4-108 with a B-W Velvet Drive (1:1 IIRC). The shaft rotation is RH.
