Hello Clanton,<br /><br />You're a gem...you answered a problem I had a few days ago and it cost me a mere $0.53 to fix the boat...what a hero. During your answer, you mentioned that if the engine was a great running engine (Evinrude 60hp) that you'd suggest upgrading the cooling system...well sir, it is, and I'm interested in anything you have to say. Can you recommend a good service manual for my boat and / or engine (Eagle 351 boat). Thank you again...
