Hi, I've recently swapped a force 120 for a merc 125 saltwater 2 stroke on my 2002wa trophy. I've read in a few places the rev limit is between 4750 and 5250. Just looking to see how high you guys are taking your motors up to . dont want to blow her and she's running really well. One other query - i had also heard that the second two cylinders are supposed to kick in at around 17/1800 revs but mine doesn't kick until 21/2200 revs. Could it need adjusting back down or would you just leave as is. Many thanks

Re: 125 saltwater rpm range

Did same swap a year ago. 1990 Force 120 to a 2003 125 SW. 2 cyl to 4cyl happens around 2200 RPM. I don't suggest sitting around 2k as the motor can be jumpy at the transition point.

Good motor.
