TX71GT160,<br /><br />I think R. Johnson is correct.<br /><br />Those engines took a rare and very bulky tilt/trim system.<br /><br />It consists of a huge bracket with twin rams. It was NOT easy to install.<br /><br />You may want to consider A PT-130 system from these folks. (see link below) It is quite reasonable and they are built very well.<br /><br /> http://www.cook-mfg.com/
