25 Seafari progress and re-power question.

Honestly I would greatly consider not going with a bracket and spend the bracket $$$$ on notching the transom for a 30" motor. I don't think there is any question that doing so would greatly improve ride, handling and the ability to hold plane as well as staying close to the designs CG.

As far as going with either a 300 or 350, both are great engines as a member here commercially operates twin 350s and they are nothing less than magical. I agree the 300 will do the job but the 350's duo prop lower unit will provided considerably better fuel economy as well holding the hull flat in nearly any condition. That said, if you are totally committed to running a bracket I would only recommend the 300 due to weight and even more suggest going with the 300 v6 merc which is even lighter.

Weight distribution is going to be a big success driver for your build. Carl originally installed a ballast tank on these hulls with I/Os so be mindful of this during your layout as going with an outboard will provide challenges to be overcome by the design.
