The common age related issue on any of the LS design engines is the Oil Pump Oring, where the pick up tube attaches to the oil pump.  As they age they get brittle and rather than suck oil they start to suck air.  When this happens you first see slow oil pressure build up on start and it gets worse slowly from there.  Common issue on all from the 4.8L to the 6.2L.   $3.00 oring and easy to replace once you have access, you can go in through the front or pull the oil pan I have done them both ways but do not worry about it unless you start seeing the slow oil pressure build issue.   I am betting in a boat where the environment is cooler and the hours used is far less you may not see this issue for several more years.  In Trucks it is usually somewhere around 100,000 miles or more when it shows up.  The Oil pressure sensors also tend to fail at the 100K plus mark so always change the sensor before changing the Oring.

Good move selling the old boat JQ, it seems like things go wrong with them just sitting and leads to repairs you do not want to do at this time so you moved it and all is good.  More space now to play with your new toy.
