Looking for any info on my new project. Title says horizon 20', interior mfg. Tag states "holmes mfg." Who designed the hull etc? Its a true tunnel with tri stepped sponsons ...it has a 20" transom and I will be powering it with a 1982 modified 2.4 formula efi offshore built by diamond marine to 270hp. 24p 15" chopper. Motor is built to handle 10k but would like to make it last. I am unable to post pics but feel free to text 2313841954 for pics. Any info would help. Thanks!
