Hi,
I have got a tohatsu 2st 25hp that i purchased new late 2005 this is on a 12 ft inflatable.During 2006 i only managed to put 12 hours on the engine,so i only just got pasted the break-in time and still running on 25:1 ratio of oil.
In that 12 hours i managed to run the engine at wot a few times with myself my wife and daughter in the boat and notice that it was only revving up to 4600 rpm(measured on a tiny tach)and 25mph(gps).Is this dew to 25:1 mixture?As i don't want to start changing props yet.The pitch on the prop is 9.6 x 13".
