Coho Lips:
Dont know what type of boat you have, but how the stern of your boat is configured helps determine what your options are. I have a Century 2200 WA which has an integrated pod/grid on the back like a Striper. Had my boat in Jenkins Marine in Victoria this spring getting some work done, and also had them put on a new kicker bracket, which was made by Adventure Marine Mfg, and was really surprised at the difference it made to the kicker performance (4 stroke 9.9 Yamaha HT. There is a little bit more to it than just bolting onto the back in that, how far it is postioned from center, and how low it goes etc.. to get the best performance. There is a mathematical formula for figuring out all of that stuff, that good marine mechanics know.

Boats run on Gas, not Thanks!
