Im sure many will scoff at this but I just thought it was nice to see others pushing the boundaries of powerboat racing. I would very much like to hear anything further on the technical side of things if anyone knows of any more.
Maybe, there has been various fishing motor cooperation over the years but at the last UIM four stroke meeting Mercury said they would not permit anyone to use their midsection or gearcase. Having said that it was several years ago and times do change.
Current favourite for 4 stroke would have to be 250 Etec , powerhead is standard but midsection and gearcase are not current production parts and come from the old OMC F1 project.
