Like i said, its your choice its just what the service manager told me.
The problem as he described to me ws the engine has about 10 more HP. When you load the system down with the V1702 it will bog down and you know its working hard, with the extra HP you won't notice its under as much strain as the engine will not bog down. Sure there are relief valves to protect it from too much load, but heat is still generated. Like i said, your choice, i was just repeating what the service guy told me. He has been working on 743's since they first came out, so i may know a thing or 2

With that said, i personally agree with *thetool* i can't see it being that much of an issue, just watch your system temperature.
