Re: E-tec and Optimax
no optimax is not the same as evinrude d.i.<br />mercury are using what is refered to as an orbital engine. back in the 80's o.m.c. looked at orbital and ficht technologies and decided to go with ficht<br />e-tec is the next generation d.i. technology motor its a simpler design than ficht motor because it uses less parts<br />probably the best thing you could do is to go to mercury's web site and then to evinrude.com and compare technology's for yourself<br /><br />hope this helps
