Hey guys I have a 263 walk around with twin Yamaha 2 stroke 200 motors. I blew the cranks on the old motors (sheared off under flywheel) The boat is rated for 400hp. I am trying to figure out the best repower option. Do I go up in size? What kind of weight will this hull handle? Can the transom handle the higher torque of today's 4 stroke? Has anyone done a similar repower? What are your thoughts? Thank you!
