Model 70ESL75B 70HP Johnson<br />Looking for info on obtaining and installing T&T. Wondering if there is an aftermarket bolt on product available for this. (like an electric screw driven type assembly) If so any info on what and where would be appreciated.<br />Would like to get some idea of what T&T would fit on this motor (model year range ie 55 to 115HP Johnson from 1974 to?? or whatever)<br />Any help with this would be greatly appreciated.
