10ga. wire in red & black colors as advertised. Product came quick & unharmed. The wire itself is perfect for finding its way through the contours of my vehicle becaue of its "rope-like" feel (unlike a stiff wire). Would buy again, because so far, so good. Hope that helps.

Old Merc Inline 6s - 1500, 1400, 1250, 1150
This is the second time I purchased from them. The kits are good quality, and impeller is durable. Pictures is the initial one I purchased from them two seasons ago. It had hundreds of hours on it, plus me accidentally cooking it for 3 mins without water hooked up to the engine - which is why I purchased it again. Given 2 seasons of use and my recent screw up it held up well.
