    Yamaha hands down, dont even look at the others. I used to own 3 f12x, 2 I sold last season and replaced with F-15x, the exhaust manifold failed on 1 hours after we sold it. My 3rd F12x had the...

    Cheaper, 4 valve vs 5 titanium valves. Yamaha had a bad batch of rods in 2016 or 2017, but these engines are strong. They can make 300 hp in snowmobiles with the stock rods.

    Ya, thats the way to do it. Its a shame there's not really any mods for the F15X either anymore, I picked up a mint one with only 40 hours last year. I plan on keeping it for a while.

    Ive been looking too, I just picked up 2 15x and sold 2 12x that I've had for years. All I've really found is the macsboost, but at $3900usd for the stage 2, doesnt seem worth it to me.

    Just get your 60hp tuned to a 90hp. I had a guy come do it for 150 bucks, and it would have been 100 if i brought him the ecu or the ski. I was just lazy.

    Great fabrication work!

    I commented on your old thread about the reliability of these etec motors. I would highly recommend rebuilding this motor before you put it to use in the water. A set of...

    What do you have for a/f gauge or are you just gonna run some race gas mixed in each tank? I believe you will be running lean if you turn the boost up at all with the pipe.

    Cool thanks for the reply.

    I know you cant compare different brand impellers, so I was mostly curious about the solas 12/15 vs 12/17.

    I see alot of people complaining about lack of RPM with...

    The Spark has plenty of power to pull up a skier. Just if you have someone good on the skis or a wakeboard, they will be able to pull the ski sideways a little while doing carves. No big deal.

    These sled engines with 160 hp are super strung out. You cant run an 800 etec at full throttle for very long. Check the snowmobile forums, when running down a...
