I'm interested in adding a kicker [or auxiliary] engine to my 1989 Whaler 27 Full Cabin. She currently has twin 2005 Mercury 225-HP OptiMax engines, and the hull is rated up to 600-HP. I don't think weight should be an issue. I am concerned about throwing off the weight to the port side and affecting ride and stability. There is currently a kicker bracket on there, and I'm following up with the manufacturer to see if it would be strong enough to handle the 120-lbs weight of a modern four-cycle 9.9-HP. If not, I will need to go with a new bracket to replace it. These look nice: .

Will 9.9 be enough to push this hull? The main use for the boat is slow trolling for salmon. I'm also wondering if I should [connect the fuel for the auxilary engine] to the main fuel tank, or install a small separate tank for just the kicker. Maybe if I put [the separate fuel tank] on the opposite side [from where the auxiliary engine is mounted] the weighting [problem] would be solved. I'm also planning to install the binnacle throttle and an auxiliary wheel on the transom so I could work the rods and the kicker all from the stern. This would make the kicker a completely separate entity from the main engines which would be nice in my head but maybe I am missing something.

Current bracket can be seen on my flickr account below:

Before you invest in a separate steering system for the auxiliary engine, test to see how much helm control it will have. I would think that you'd get better control by turning the twin outboard engines as just rudders when they were not running.

My brother in law has a 1990 Outrage 25 powered with a single 275 Mercury main. He uses an electric start Mercury 25 as a kicker. I use an electric start Evinrude 15 on my Outrage 22 with a single 200 main.

We have both found that, in a stiff breeze, there is nothing like plenty of directional power. Both our kickers are light, older two strokes. Both are set up with steering and controls at the console.

I would want more than a 9.9 if I were in your position.
