Pusher or puller????? The answer is in the engineering. You can make either/or out-perform the other, its all in how you want it to run and what you are expecting out of the boat. I like the puller set up personally, and I have no problems with heating or with the handling on my set ups. I can turn them in any radius I want...tight water-nuts or long sweeping turns. The key is finding what works best for you and how you want it to run. Some build for performance, some build for pleasure. I guess what I'm trying to say is....just build and tweak, you'll find what works best for you. The other factor is getting to know your boat and how it acts and reacts.

Good luck with your projects....Have FUN!!!!
