On Trackers web site this model is offered with an option for the Mercury 150 opti and the 150 four stroke. I am not sure about the weight of the opti but the four stroke comes in at 455 lbs. My question is would an additional 50 lbs hung on the transom make a significant change to safety or performance ? I have the come across a new 2017 PT 195 with no motor and possibly a great deal on a lightly used Etec-G2 150 which tips the scales at 507 lbs. Just looking at pic's of this boat it certainly appears bow proud as it is.
