Hit Rock Motor Wont Start

[Charlie0821]

Hi All,

This weekend after a great day out on my pontoon I hit some rocks on my way back to the slip. The engine shut off and wont start back up, the prop and lower unit have no visible damage. Any idea of what could be wrong and how I can diagnose it before I have a repairman come look at it? The motor is a 2012 Mercury Outboard 50hp Bigfoot. Thanks!

You hit a rock and no damage ?------Check lower unit oil for metal bits on the magnet.----Maybe there are internal engine issues .

Does it crank? Does it crank over too easily/fast? Check your flywheel keyway - it could have sheared off .... Longshot.
