Hi, Im new to this list and I find it very interesting and informative.<br />Im in the process of getting twin 200hp engines and Im stock between Yamaha 200 HPDI and the 200 Mercury Optimax. They are both fuel-injected engines. The Optimax weight more than the Yamaha but the Optimax has more power. Im gets a 26-foot opened fisher. If any of you have any information related to this matter I will appreciate any help I can get. As you know these engines are very expensive and I will try to do my best in deciding what engine is best for me. Thank you.
