Have been kicking this around as a winter upgrade.. Worth the $800 problems??

Good info here.

gives you better midrange and also if you have a soot problem on the transom after running it for the day, you will have significantly less. My props will only turn 5300 right now so I'm not taking advantage of the 6000 rpm rev limit, probably best on stock springs
