i have a 16' aluminum deep-v. It had 50hp mariner on it with 15P prop. I traded the 50 for a 75hp. I was going 'start' with a 17p on the 75 and go from there, but the prop selector here http://www.mercurymarine.com/prop_selector says for me to start with a 26P. That seems very tall to me, and quite a change from the 15P that was on the 50. Where would you start? The boat alone is probably weighing between 1200-1500lbs. The 50 would push it about 26mph, and pull my son on a tube around 12mph (he said it was fun, i didnt believe him) anyway, i'll be doing mainly fishin, but the motor will see a fair share of watersports too. Whatcha think? oh and ah, no i dont have a tac yet, the harness has the "grey" wire in it, but i cant locate a model number for a tac that will "plug n play".
