Re: new boat owner what should I grease
You will need to let folks know what kind of rig your have. Probably a stern drive unit since you posted on this site. Mine has a zerk for the Gimbal on the stern drive and two for the trim.
I also have a zerk for the drive shaft in the engine compartment. Then there are the steering, fuel, and shifter linkages than need lube.
The drive lube, trim lube, engine oil, and steering fluid all need to be checked, replaced or topped off.
But, based on personal experience do not forget to check your trailer brakes if you have one.
