Default Dreaded 7-3 code

I bought this motor used from OS a little over a year and I've loved it. 26 miles offshore on Saturday I got the alarm and this code and also a message about checking the throttle assembly. Engine ran rough at idle and would only make 5 kts. Once we got into cell range (15 miles) we were able to pull it up on the internet where a THT'er had mentioned leaving the engine off for around a minute. I had only turned it off for a few seconds (lesson learned). That cleared the code and we cruised home. The problem repeated one more time later that day but the next day we went to the sandbar and had no repeat problems. That same THT'er said they never had the problem recur while others said it's a TPS sensor. Do you have any insight on this?

7-3 if for an electronic throttle valve(ETV), its possible it could be hanging up on you. Its the large butterfly air intake on top of motor, could be corrosion, dirt, etc. build up and causing sticking. It could also just be malfunctioning. If it still has warranty, it is a covered component so we could just change it out to prevent getting stranded again.

Engine ran fine for a couple weeks after first throwing the code then last weekend we heard a whistling sound like air being restricted (stuck butterfly as suggested above maybe?) and today it's going into limp mode each time we slow to idle speed so looks like I'm going to need to bring it down to OS.

Sounds that way. Give us a buzz so we can get you on the schedule and see what your schedule will allow.

Big props to OS here. They diagnosed my problem on this forum, got me on the schedule pronto, I dropped the boat at 9 am, they confirmed the diagnosis and fixed my problem (under warranty) which was a new throttle body, and serviced the lower unit with new oil and a new water pump, all by 2 pm. Then I was out and on the road back home. Their confidence in the Suzuki aftermarket warranty process (I'm in year 5 of the warranty) was very comforting after I had read some stories on here. OS is a quality operation with quality, prompt service and great prices... and as a result they need a bigger parking lot!

Thanks for the shout out, much appreciated. We are definitely tight on space and the parking lot gets jammed up real quick with boats coming and going, sorry if it made for a tough situation pulling in.
Thanks again, Mike

No problem for me at all. Your guys are amazingly fast and agile at moving boats around. They had to move 4 to get mine out and it took them like 7 minutes.
