No problem putting an emergency standby kicker on a 225 Freedom. I purchased a 2008 225 Tournament in Singapore last year and moved it up here to Phuket Thailand. I'm in the process of installing a Yamaha 9.9GMHL High Thrust on a Garalick Bracket this week (23/4/12). I saw another GW225T at the Ao Po Marina in Phuket with the exact same installation. The resort that owns the other 225 had the GW dealership in S'pore cut out the recessed part of the swim platform where the swim ladder normally rests. The Garalick Bracket is then thru bolted directly onto the port side of the transom with two large 3" x 12" S.S. backing plates. An access panel/inspection hatch has to be cut into the cooler/fish box to fit the bolts. For fuel, a T-fitting is installed down-line of the Racor water separator. The swim ladder can then be repositioned over to the starboard side of the swim platform.
The stern of boat will tend to sit a bit lower than normal with the extra 125lbs bolted onto the back-end but I have offset the aft C of G issue by moving the two AGM batteries (130lbs) forward, above the deck, under the helm. This not only helps balance the C of G, but also provides much better access to the batteries with access through the hatch where the tackle box once sat.
All boats over here on this side of GMT have to have some sort of back-up. With no SeaTow or Coast Guard over here, the Andaman Sea/Indian Ocean is not the place to be adrift.....with the tide going out, the sun going down and a storm on the horizon.........
