I have a 2015 Hurricane Deckboat with a Yamaha 115HP OB. I have lost all power. Anytime I hit the throttle the whole boat vibrates and wants to stall. The boat will idle fine. Any idea what could be causing this?
Could be so many things. Easiest of them all might be if you have a remote fuel tank and vent is closed. But just a guessing game without basic trouble shooting as Scott above says.
