Go here for more info: http://findarticles.com/p/articles/mi_qa3918/is_200412/ai_n9469571

Running 12 to 18 cells on the stock 600 motor will burn it up quickly, and I doubt the ESC would handle it anyway - do not try it! With the stock setup I'd not use more than 8 to 9 cells, and prop down if you try this. The tips in the above link will help you get going faster safely.

I would ask at Offshore electrics for the best 700 motor; they can match your budget with the right motor. Note that the shaft on the 700 is larger. The best ESC would be from RC-Hydros.com, although offshore has some others too.

You get what you pay for with cells. Top performance means spending more $$$, but for most sport running you can get by just fine on less-fancy cells. Remember that all the power in any boat is in the cells; lowest price cells equals lowest performance.

Battlepack cells are good, I've set SAW records with them. :cool:
