I have a 11ft 97 Mercury Quicksilver with a 15hp 2stk. Mercury motor of the same vintage. I love it and use it about 3 times a week in the Rivers, Lakes, Delta & San Franciso Bay surounding where I live. I also have a Hydrofoil install and I stand by the preformace of this part as it is the best upgrade you can make on a inflatable. It planes almost instantly (about 1/4 trottle 5-6 knots), with a top speed of about 24mph and remain on plane at slow speeds and get better fuel mileage. I'm planning in the future to get a 4stk. and at that time I will upgrade to a 20-25hp for a little more top speed and to help out with the weight of my 3 dogs(85+lbs. each) that sometimes join my wife and I.
