2014 Spark 2up 90 ho Unresponsive throttle and flutter on back off


New Member
My 2up throttle response in touring mode is much less responsive than my 3up. Is this something that could be normal due to the expectation that the 3up would have more weight?

Also my 2up has a lag/flutter when i come off the throttle and RPMs come down. On the water it feels like a slight sticking throttle, on land its clearly a deceleration flutter. 3up is smooth up and down. Any ideas what could be causing this? both have identical idol RPMs.

Sports mode on the 2up does not experience the bad response....i forgot to check if the flutter is present in sports mode though!
