I've recently re-powered from a Force 120 with an in-line 10 micron separator mounted on the motor well. During the sea trial with 3 aboard I didn't notice this phenom, but the Optimax, at 5700 rpm's begins to miss after 2-3 minutes with myself only aboard. I cut the throttle for a bit and the engine goes back to normal, but, when I get it up to @5700, it again begins to lose power. The outboard idles fine and gets the boat on plane in a jiffy, but the high-end problem has me a little puzzled. I pulled the cowling off and there is a 2nd spin-on fuel filter. Is the reason for the high rpm miss the 2 in-line fuel filters? Should I by-pass my old separator?
