I have this exact same ski, it's an old ski now but still a great one. I bought the RPM kit I have done the air filter and the intake grate and got 2mph on top end with those two. I have 3 more mods to do on it, will do the prop and the free flow exhaust and then will send the ride plate off to Jims to have it modified, I am excited to see where it will end up.

ok, yeah i have the stacks and filter already. I have been wanting to get the solas impeller but from what I have gathered I may need the exhaust too.

Those would be minimal if any. These mods are what is called a RPM Kit which basically improves airflow on the high end and gaining you a few hundred RPM which in turns equals more top speed. Bottom end will be untouched except for what the impeller may help with.

It should net some nice gains if you do all 3. Somewhere in the 3-4mph range.

Did you notice any performance gains? I have an 05 fx cruiser ho. Already have the velocity stacks and air filter. Been thinking about doing this for some time along with a solas prop. Whats your take on it?

I'm getting a 2007 used Yamaha FX HO, i want to do the same, did you do of these mods yourself? Thanks

Hi can you remember the part number for side exit exhaust kit ??

what keys are needed for the Yamaha FX HO 2007 to start it

I am mainly looking for bottom end gains

Sound better be4
