I have digged out this FB big boat from the storage after 17 years, it measured at length 52" and 26" wide. repainted it and my friend put a standard 26CC Zenoah on it to try, but it is not rising at all.
X-470 octura prop,light load on motor,tuned pipe set at 12.5-13.5 inch to center band following pipe from flange to center band.stock motor will handle this,set strut level at 1" depth from bottom of hull!
