My other son and I are looking into a new (very fast) planing boat in the 80 ft region for him with surface drives. Having looked at and tested the Arnesson type surface drives, I found an very old post about Seafury Surface Drives from Down under. They look much simpler as far as maintenance and operations are concerned. I would like to hear the opinion of our fast boat specialists about this system, especially in a multi engine enviroment (i.e. 3 engines). Would be very nice to hear from somebody with personal experience (Reliability, performance, Noise level). We have no other knowledge than some pictures, videos and their website.
