Ranger/Yamaha 200 Pro V


I own a 1994 Ranger 492VS with a 200 Pro V. I read one of your posts stating you have gotten older Rangers to run 70's. Everything on the boat is stock and I was wondering what kind of mods I can do to the engine/boat without spending thousands of dollars that might get a few more mph faster. I was told there is a carb. mod that will gain approx. 25 horse, is this true? Any info would be great.

Thank you,



It's true, there is some power to be had from your 200.  The carbs are already as big as possible. The same as the 225, the 200 uses the pro V150 tuner and a change to the 225 excel pipe is worth a few horse. Mostly, we try to make them like the 225 (they are only 10-12 horse apart) and work on jackplate/prop setup. I have several 492's running in the low 70's, but need more info. on your current setup to make any calls on the next step. Hi-compression heads are a no-no from a reliability standpoint with "lake" gas.
