On the tour boats we now have Suzki 90's. 1300 on one set, 800 on the other.
We considered E-Techs, could not get any commerical applicantion feed back, so we stayed away. We we considereing Yam or Suski and selected the Suski.
Previous power was Honda, one boat had 90's got 5,500 hours on them. The other had first Honda 115' they failed, bad heads, factory replaced with 130's. We ended up with 5200 hrs on the 130's.Did not consider Honda, we had a lot of issues. We run in shallow water, a lot cooling issues. They showed a lot of rust early on.
Could not find one commerical use of E-Techs in our area that would give us any postive feed back. Our application is much different then most, we go every day, and a multitude of different operators. We did get good feedback from several rec users, that was not sufficent for us.
Good luck
