Here's the deal I run two E7 300 mechanicals in a boat. For my setup they work great. I'm needing a few more horsepower. I don't know too much about motors, but was wondering if I need to buy a set of 350's or 400's. Or could you soup them up? I want to stay mechanical. Mine are 96' motors. Any help would be greatly appreciated

Got any pictures of your engines? Never seen marine mack engines. Seems to me the easiest way is just to swap the pump injectors and turbo from a 400. Maybe you could buy a couple of 400s and swap out the parts, and have a bunch of replacement parts as a bonus.

Timmy,

Now that you mention it, I do not remember working with any pump other than RBosch for the E7 (mechanical or electronic).

And you know how all trucker stories start...."you are not going to believe this but....".
