Hi, my first post/question. I just picked up a pontoon boat yesterday and it has a 1997 50 HP, J50ESLEUS.I don't see the S suffix listed anywhere. The manf date is 04-97. The only reference to this exact model is on the NADA site and it says no tilt/trim. Did this ES motor not come with a tilt trim? Any info on the S production compared to the R production run would be appreciated. Thanks
