Quintrex 481 Fishabout Pro Testimonial

We are enjoying the boat. It is a great all rounder and we have spent many hours fishing & towing the kids. my only regret is that I didn't realise I could have got the 90hp Evinrude on the boat. I feel this would of suited my needs better. Could you supply me with a price to change over from 75hp to 90hp. Thanks,
