Diagnosed problem of rough idle of a Suzuki DF115A on FD196, I need fuel tank knowledge.
I have a 2020 FD196 with a Suzuki DF115A. I just completed the 20 hour break-in and service. At or around 10-12 hours noticed a rough idle condition which progressively got worse. Took the boat to an authorized Suzuki marine dealer, with a complaint of rough idle. The technician took the boat out to test it and said he didn't see anything abnormal, $150 dollars later. So I realized I would have to find it myself. I tracked it to the down tube in the fuel tank having an air leak. The area is extremely tight making things difficult, but what I need to know is the construct of the down tube fixture. From my observation it appears that it must be installed/removed from the inside through a larger access hole. If this is a case the I need to know to decide if I want to do it myself or not. The problem apparently unknown earlier because with a full full tank the problem might not manifest itself. Another question, the boat is now just over a year old, will this problem be covered under warranty? Hopefully since it seems it was probably there the entire time. I don't want to risk using the boat in case the air leak suddenly gets worse and leaves me stranded. HELP PLEASE!
