I would guess that an idle problem is related to either a vacuum or fuel leak.  You could try spraying some starter fluid around the base and seams of the carb with the engine idling to see if you get a bump in RPM.  Fuel leaks may be harder to deduce, but double-checking the float level is a great place to start.

I have an 02 Sportster and have been having carb issues as well. Your carb is likely a Holley 4160. I can't for the life of me get my carb to idle consistently or run well in low gear despite a rebuilt a few years ago. Just ordered a new one from Holley two days ago. Luckily, if you need a new carb, the 4160 is on sale from $900 down to $625!

I believe if an Indmar your carb will be like this one:  idle speed adjustment is done via screw 175/176 in diagram.  Google Holley carb and lots of info at your fingertips.

Great looking boat and set up.  Congrats on the new purchase!  You are going to find yourself loving all the new tech and features!  (I will spare the jokes on the Kent St flag....Can't read, can't write....LOL.  MAC educated from OH here, as well  ...)

I have never pulled my bags.  My boat is dry racked - so I may be less susceptible to water / rain and all.

I am thinking in all four boats we have owned, the depth finder has been good and never needed calibration.  Our dealer does an AWESOME job in putting ten hrs on them before delivering.  I.E. all these types of things are worked out prior to me pulling away.

I think I'll just go to the bar and buy some pull tabs rather than doing anything with rec vehicle stocks.

It's not all bad.  Patrick Industries stock went over $100/share back in January while things were slow.  Started a steep increase in October last year while the RV industry was really slow.  Can't rule them all out.
