I have a Moomba Mobius xlv 2007 with the indmar 325HP engine. I have had it for about 2 months. I noticed last night when setting up to pick up a downed rider that when you back off on the throttle and you are looking for neutral it seems to rev up a little as you go into neutral and then takes about 2 or 3 seconds before it drops in to idle. I am not sure that is a new development or not. I may be out on the water tonight or tomorrow, anything I should look for to help diagnose a problem. All other operation away from neutral seem to be OK. going from neutral and into reverse seems to be normal. The boat does not move in either direction in neutral. Maybe I am over vigilant.
