I got a 2010 Tracker 175 TXW with a 90 hp Optimax, From what research I have done 2010 was the only year that the 175 was offered with a 90 hp motor. Even the new ones I looked at only have a 75hp motor and you have to pay extra for the 75, 60hp is the standard option. Did I get lucky finding this boat with the 90 on it? Also can I expect 50 mph top speed with my setup? The ones with the 75hp seem to top out in the low to mid 40s depending on the load and conditions.
