depth gauge,hard start

[lake dweller 9]

Has any one have issues with there depth warning going off in deep water, mine will alarm and say 1-2 feet when we are in 30+ feet of water then it goes back to normal? Other issue is when engine is hot it has a pretty long crank time before starting,it died once at idle but then fired back up. Boat is a 16 s211 with the 343 I just did fuel filters ( both of them) and added 30 gallons of fresh gas.

On the depth warning, happens all the time.  I'm in 200-300' of water.

...and my temp is 10 degrees or so off. Dealer says supreme is supposed to have a software update for some of these issues, but it has been a long time coming.
