Just baught a 1976 johnson 70hp seahorse. It needs a foot, what years, and hp range will fit? Also what should i expect to pay for this foot, and what should i look out for before buying it? I do alredy plan on resealing, and installing a new water pump before i install. Baught it for 40.00 from a reliable friend, and he says it ran perfectly, so i don't have much into this. Thanks for the replies..
