I searched and couldn't find much on the subject. One guy put a 600hp nascar engine in front of a electric shift and blew the lower unit at wot turning 7200rpm... trying to turn this old a drive that fast was just stupid...
I have a 351windsor stroked to 427cid that is just sitting in my garage collecting dust. It produces a ton of torque from2k on. It produces 450hp at 5400rpm and 520ft/lbs of torque at 4200rpm or maybe it was 3800rpm... It wont make that much pushing through the stock exhaust and I wouldnt go past 5000rpm So considering it is a direct swap for my current Windsor in the boat I was considering swapping them out. do you think the OMC electric shift is up to the power?
From what I have read the upper gear head is pretty bullet proof if you maintain it and I can get a rebuilt lower unit with a two year warrenty if this older unit pukes but will it hold up? I am takeing precautions to ensure a stable consistant power supply to the coils since that is how I lost the last lower unit. Other than that is there any reason the drive cant take this power if you aren't stupid with the throttle?
