I have a 2014 Bass Tracker PT190 with a Mercury 90 Four Stroke Motor. I can only achieve a top speed of 33 mph. That's with full tank, two people, and normal amount of fishing gear. Other things I have read, seem like I should be able to move faster than that. Motor starts fine, idles, and runs fine. Far as I can tell. Original style prop 13 x 19 blackmax.
Any thoughts?
