You have to adjust the idle with a scan tool then. In neutral, adjust the mechanical stop so the IAC rest between 0-20 counts (have to let it stabilize). Then, in gear, it will go between 80-140 depending on prop and gear ratio.

You must also clean the IAC filter (on Whipple kits) a minimum of once a season, otherwise it won't get enough air and will idle all over the place.

thanks, I'll try it

No problems with mine but it does help to pause between shift manuevers. i.e do not go directly from forward to reverse, pull to neutral for a moment then back into gear.

Chuck,

Give me a call tomorrow at the marina. I had the same issue with one of the boats we had in the shop.
