Advice Please

Hi All,
Firstly thank you for letting me join this awesome forum!
I have a 3.0 MerCruiser inboard and can’t seem to get the engine to crank after sitting for 4months.
Battery good as have kept it charged, no corrosion on cables to starter solenoid, starter relay clicking when turning the ignition switch.
When turning the ignition switch, there is a fan type of noise coming from the engine but does not crank.
Do you think the starter solenoid could be the issue or something else?
Appreciate the advice

sounds like the starter is spinning but not engaging...could be solenoid or gear...or ring gear on the flywheel...

Changed the whole starter motor/solenoid and all good now. Suspect it was rust or starter solenoid. Thanks all, just in time for Aus summer happy days!
