Our outboard is an Evinrude 225 HP, 1994. I would like to know if operating the boat at low speed (maybe not even reaching plane speed) for a small trip (6-7 nm plus return) would cause damage to the engine ? My wife went through surgery some weeks ago, and even when she is now well recovered, I would like to avoid jumps/bumps in a trip we are planning to the beach/islands next saturday.<br /><br />thanks
