hello to you all. can anybody please advise on a question of weight. i have a mayland 14" boat and run an 15hp evinrude as main engine and used to use a 4hp evi two stroke as back up. i have recently bought a honda 5hp four stroke as back up. back up engine sits on an aux bracket bolted through transom. can anybody please advise whether the honda(27kg), and the 15 evi' will be too much for the transom.many thanks for any help.cc
