ORDER INFORMATION: SEND ALL PARTS REQUIRED FOR MODIFICATION VIA UPS or FED-X TO:
GROUP K • 4597 CALLE DEL MEDIA • FORT MOHAVE, AZ. 86426 • (928) 763-7600
ABOUT SHIPPING YOUR ENGINE: UPS & Fed Ex both carry up to 150lb.(easily enough limit for any twin cylinder pwc engine). Many customers opt to construct a framed plywood box with angled base pads so that the motor can be screwed directly to the box for shipment. If sent in this way, we can return-ship your engine in your “good-condition” box. If no “preferred box” is used, we will bill $25 for packing for the return shipment.
Upon receipt of your engine, we will perform an initial teardown and evaluation before contacting you with estimate information. Please note that engines with heavy corrosion damage may be considered “non-serviceable”.
