I would like to install a kicker motor this winter. I have my eye on the new four stroke Mercury 9.9 Pro Kicker, looks like a nice fit. At around 107 pounds I think it would work out well. Electric start and remote shift/throttle. I would like to steer by connecting the kicker to the main engine.

Transom is the 25" notched.

Any information on how the motor is installed (secured to the boat), shaft length and the steering is set up for this boat would be much appreciated.

I have the 8hp 4st installed on my 17 II outrage, its the same engine as the 9.9 . I think you must go at least to the 15hp 4st. asaf

I disagree with last post and think you will be very happy with the 9.9. I run a 9.9 Yamaha HT 4st on my 24' Outrage with plenty of power. It will move boat about 7 knots at WOT. I doubt a 15hp would move it a knot or two faster. The hulls want to push too much water above that speed. I run a 25" shaft bolted directly to my transom right next to the main engine. The deep vee is such that plenty of clean water is available to the prop. The cavitation plate is above the hull bottom but it presents no problem because the engine will not plane the hull. I have never had a cavitation problem and have run the boat in ocean swell. A dual binnacle throttle makes a nice clean instatllation at the helm and I run a tie bar between the front of the two engines. This set-up works great. Take a look at the kicker installation article on this website.

Good luck,

the new merc 9.9 is 210cc disp. the yamaha 9.9 shares the same block of the the old 9.9 and 15 hp of 323cc disp. this is a much stronger engine.

Appreciate the input as always. Had a chance to take a good look at the transom yesterday. Looks like the motor can fit right on the transom as you stated aquanut. Hope so, would make installation easy.

Yes asaf, the 9.9 Mercury Pro Kicker is a smaller displacement engine, but it has the bigfoot gearcase and gear ratio, plus a big four blade prop and power trim. It is designed to push heavier boats at displacement speed. At 107 pounds with power trim it is a nice fit. I would also like to stay with Mercury because that is the make of my primary power, plus my Mercury dealer is excellent to deal with.

The kicker installation articles are excellent, will certainly use as a guide for the install.
