Sorry for the delay – work’s been in the way of lots of things lately.
On the newer 618T’s the batteries are under the back carpeted storage hatches on both sides of the engine new 618T layout. I didn’t like the carpeting as they will get wet (it’s a tiller) and then you have more weight to overcome. On the older (prior to ’09) models the batteries were under the back rigging area – just below the motor handle.
Kurt Turner is the guy to talk to on this. He owns a 618T and has put it through the paces. He’s had wheel boats prior when he was fishing tour events so can give you a good pro/con on this. He should also be able to weigh in why he chose the 618T vs. the 620T. Here’s an excellent feedback he provided on the 618T on another site 618T thread.
If you want to discuss 620T’s or a demo ride let me know – that is what I am currently running – but I am in an ’06 hull w/ a 150 E-TEC. I didn’t like the full layout of the newer 620T’s and was skeptical of the new hull in ’09 (batteries in the bow could potentially have a negative effect on speed as you need to overcome the weight w/ bow lift and could be an issue in larger waves) which drove my purchase of an older hull that still had the 150 rating.
Specifically on the 618T I want you to get a test ride and pay attention to your motor choice. Everyone would appreciate a 115 hp rating with a hydralic steering sytem on this hull, however a direct injected two stroke with the extra torque for a better hole shot will clearly show it’s benefits when you have a full load of fuel, gear and fishermen. Additionally look at keeping to a 24V system to eliminate another battery weight along with the $ savings of a battery and 24V motors are usually less expensive.
If I can be of any further help don’t hesitate to reach out to me via PM or [email protected].
