G'day insideout, sorry mate just sortin out the platie boys Mate the 5.2's are a kickarse boat. A little boat with a big heart. Ive been out in some ugly conditions (3 metres 30 kts) and always felt safe. With the 60 high thrust yammies which im upgrading to, fuel economy is roughly 22 litres/hour for both motors, or 1.6klms/litre. Have a read of this if it works ill see if I can find it. I hear the sailfish 5.5's are a good boat I cant comment, id say go for a run in both and go from there. I'll see if I can find this.
