Want this question answered?
freeze plugs are located along both sides of block also at rear behind the flywheel.also have smaller freeze plugs in heads these plugs are used to fill holes that are left in the block and heads after casting at manufacture. the holes are there to facilitate the removal of sand used in the casting, otherwise the blocks would be a solid lump om steel with no water chambers contrary to them being called freeze plugs, they do not stop an engine freezing and certainly do not come out of block when coolant does freeze if this happened we would not get cracked and broken blocks in boat engines that were not winterized in time for the winter and most boat engines are just a marinised car engine

2003 for highway applications. It's still in production as a boat engine for Mercury Marine.
If it is a 2 cycle engine, it has no oil filter. If it is a 4 cycle engine, the filter is located under the engine cover.
Mercury outboards are best. Johnson Sea Striker series is good too.
Mercury Marine uses a lifting eye that threads into the flywheel hub for mounting, and removing, the engine.
To fill your Mercury Outboard Trim boat motor, lower your engine to a 45 degree angle, Make sure your boat is level. Remove fill screw, and add the amount of fluid required to fill.

Perhaps the spark plug system is not sending electricity to the spark plugs.
No, a marine engine is going to use corrosion resistant components in the cooling system and the freeze plugs. Also, the camshaft will be designed to meet the different power needs of a boat as compared to a car or truck. A car engine to run be used for the majority of the time at half or less of the RPM that it red lines at, where a marine engine is most likely going to be derated to run at "top speed" for the majority of the time which wil be well under the red line RPM of an automotiv engine.
