More of a rant than anything because I'm so aggravated but lost our port coupler today while idling out of our marina tho get gas for a 3 day trip we had planned. No dramatic failure, just a clunk and a stall. Started back up no problem but temp was slowly rising and no thrust. Confirmed at the dock I could spin the prop in gear with a wrench on it so the coupler has completely let go. Not that inboards don't have their issues but I'm really sick of the i/o nonsense.
