After an eigthy mile tow in 30 degree F my 2008 Optimax 200 (purchased new this year) would not go into gear after launching. My nephew was at the ramp and said to let the motor warm up and it will shift normally. His 2006 Opti 200 has been doing the same thing since new. I've owned several 2.0L and 2.5L carbed and EFI Mercs and none operated in this manner. Is this normal to 3.0/Optis?
