3 Retrofit installation
3.1 Installation preparations
Theinstallationcanbeperformedwiththemastinstalledontheboatorunstepped.Someminoradditionsto
theexistinggearcutoutarerequiredtoallowttingofthemodiedgearwithclutchadded,andmotorunit.
Installation Cut-out drawing per Mast section

withthexingholesonportandstarboardsides(e.g.winchhandlepocket,cleats).
Thisinstructiondoesnotcoverhowtoroutethemotorconnectioncablesoutofthemastasthismay
beuniquetoeachinstallatione.g.masttype,mastheel/basecongurationandindividualpreferences.
