Wiseone,
I think you might be waiting a while for a response, but to be fair, a guy down kiama way has a 6.4m plate boat with a 200hp e-tec (HO very thirsty, 200litres a day) that raises a few marlin but i have to say that the sound of the aluminium hull slapping on the water has got a little fish raising ability aswell it probaly sounds stupid, but who out there owns a e-tec powered fibreglass hull that catches fish on the troll regulary??
By the way the guy with the plate boat i was refering to is buying the same hull and installing a diesel sterndrive (80 litres a day) ready for next season marlin season.
I would love ride in your Black watch if a spot is available.
regards Matt
