No real diffence in the pan persay . The diffrence is on the inside . The v-drive pan sits in the boat backwards which means in a marine pan app. there is going to be baffles for oil control and will be realative for each application . A v-drive pan also requires that the oil pump pick-up be extended to the front of the pan and therefore the baffles keep the oil to the front of the pan as well . A jet pan , pick-up , baffles are set-up more like it would be in a car . Can I confuse you any further ?

Well said!, Did someone quit drinking?

Another difference is that jetboat guys always use used stuff (read cheap) and Vee-drive guys only use top dollar, brand new chiney stuff.

J/K beerjet, well, not really...
