Here is your feedback on ATK engines; I used to sell remanufactured engines years ago, and in many cases you do get what you pay for. I would NOT recommend an ATK engine for ANY application. Many of them are assembled down south, and they are a pain in the *** if you need to file a labor claim when it fails. For a marine engine especially, not a good fit; when you consider the load that you have a marine engine under. Jasper does build a good engine, but they are way overpriced and you are paying them for their "warranty". If you want cheap, buy it from Autozone, and you will get the same ATK engine(or the option for an ATK, they also sell a PROFormance engine, which is fairly good), and at least if you buy it there, you have a brick and mortar facility that you can talk to if you have an issue. If it were me, I use a local rebuilder that I have a great relationship with, and he does a tremendous job. Try to find somebody that does some performance engine rebuilding locally, or if you want the number of my guy in Missouri, he can ship anywhere I believe. Also, Blumenthal's in Oklahoma City can ship just about anywhere, and they do a damn good job. I think their website is
www.blumenthalautomatics.com. Good luck, don't buy that ATK!
