That is a good question- and the answer I got is no.At least from what I was told. A 10 amp rectifier is for a regulated charging system,while a 35 amp is part of a non regulated system. Apparently for it to work you need to change the whole charging cct over non regulated as it can wreak havoc to your power pack,which is what the previous owner of my 91 Evinrude did.
I am still looking for a reasonably priced power pack.....
