Here is a video link of Will
@JetBoatPilot showing how he recommends spraying down the engine. I believe he is using Corrosion X in this video (Red can, green substance). Corrosion X HD is more brown, and forms what they call a “self healing skin” the will not allow the salt to attack your hose clamps. There are something like 40+ clamps on each engine, just following each hose, and ensure you spray the clamps. The unseen area, is what’s under the swim platform - often referred to as the lower bilge here. Get a flashlight and look under there, you should find another 8-10 clamps (each thru hull fitting, as well as the exhaust (water box) - which kind of resembles a large round muffler. The silicone spray works as well, however in my experience does not have the staying power of Corrosion X, so what you save upfront on the can, you lose in time and effort in having to reapply frequently.
Another well regarded member here suggests using toilet bowl wax to seal the steering and reverse cables from water intrusion.
It will all make sense in time. Watch some videos, read up here, and ask away. Also pictures are helpful when asking questions. While I have a different model, I did upgrade my deck latches, because as
@Dixemon stated, the stock ones will pit and then become brittle from the salt over time.
If you haven’t already, go to harbor freight or the likes and get a water proof box with a gasket (I purchased a large “ammo box” from HF), and make yourself a tool kit - screw drivers, pliers, metric sockets or ratchet wrenches, as well a a knife - never know when you will have to cut a rope.
