always trailering.

it's a short drive to the ramp but the first trip starts out w dragging it from MI to TX

I did all of it on my 2013.  Only time it went back to the dealer was to trade it in.  There are a few more items on the new boats that may or may not be a bit more complicated, i.e. coolant, fuel filter, etc. that I will take a crack at when the time comes.  I am on a lift year round and try to avoid taking the boat out of the water unless I really need to...  The biggest challenge is being enough of a contortionist to be able to reach all of the components.  Doing it yourself saves $$$, but also time off of the water in my opinion.

Outside of the maintenance schedule, just looking around for problems.  For example, a couple of years ago on my 2013 if felt a bit of a clunk / slop when checking to see that the prop / shaft was rotating freely (by hand).  This led to to find all 4 coupling bolts pretty loose.  Quick easy fix that prevented an issue from becoming a problem.

Who here does their own service?   Are there things that need to be done that are not called out in the maintenance schedule?   Thanks in advance

The part I am looking for looks like the red cap shown on this picture (the one circled to the right):

I believe it's this linked below, and any 3/8 id hose from the auto parts store will work.
