Re: pro team 170 bass tracker 20 hp mercury info please.
my buddy has a similar tracker w/ console and a 40hp and its a SLUG. So I can imagine how slow yours is. I know w/ jet drive outboards we use a ratio of 25pounds per hp (at the power head, jets lose 30% at the pump) to figure out what size motor would be best for a given hull (weight of hull,gear, passengers, and motor combined). Not sure if this ratio holds true for prop driven boats as well. if so a 20 hp will only effectively push around 500 pounds of boat, motor, people, and gear. In most situations, going w/ the boats max hp or 1 motor size down is the ticket.
like stated above tracker keeps the price down by putting too small a motor on their boats. I know a few guys that went through this.
