    Had some issues at first with the motor but Power engines really stepped up and went above and beyond to correct the issue, Shipping was very timely amd packaging was perfect.
    Follow-up from: r***a- Feedback followed up by buyer.- Feedback followed up by buyer.
    UPDATE: Fantastic customer service when dealing with the issue I initially reviewed on, I will state I posted a review before giving them a chance to correct the issue and That was unprofessional of me to do. Shipping was extremely quick and instal was smoot except the timing issue we faced. However Power Engines has been very responsive and a pleasure to deal with I would definitely recommed them to anyone.
