Definitely NOT an insert pump. Both cables in the wrong spot AND the water line on the wrong side. But it's set back far enough to look like an insert pump. Then again..... I saw a boat last week that had an E pump with a C bowl conversion that included the cables and what not. It's possible it's and E with G gear on it. It might have been on Adam's Witchcraft, that or that other guy's Taylor SJ that was out there a couple of weeks ago. One of those two had a morphidite pump/bowl setup.
Don't think it's anything like that though. The water tube is a bit hard to move. 12JG has the water tube on the same side as a A, C, or E. I can't find a diagram, but what about a 12JB?
