I have the number one boat with the Evinrude on it. I have had it for over a year now (and owe Lee and Doug a beer for not getting them out in it for a demo when they wanted it) and it has now done well over 100 hours without a hint of a problem. The tubes are excellent and have worn well with several people climbing over them with skis/boards on, the ride still attracts positive comments from seasoned powerboaters and ribbers and the economy is exceptional (because of all Dougs comments about being light/quick to plane etc). Mine has a 15 pitch prop on it which means that it cruises at 24k at 4k revs and maxes at 37k which is fine for the Solent in most conditions and I have only ever wished for more speed when I am commuting on it (I sail a LOT from Cowes) and the water has been flat. It runs at about 10l/hour (as does the no.2 boat with the Mercury Optimax 115 because we met up and checked!). I am really pleased with and will probably only change upwards to another Leeway.
Sorry for the late reply but I have only just been introduced to this forum. To be honest I was aware of all the "providence" grief of the design when I bought it but didn't give a f**k if someone was feeling precious!
