To seahorse and brian03,<br />Thank you for the info on this engine. You should also know that the lift pump and main fuel pump should be upgraded also. An evinrude tech. said my ecu was okay. Should I be concerned that it could go at anytime and just pay the expense and get it upgraded? How can I tell if it has been upgraded? Are their any signs that an ecu is about to go? I would also like to hear back from anyone who has this engine, to let me know what they think about it. I will also pass along any info I find out about it. Thanks for all your help.
