I have a 2006 2360 that is great, but am wondering what the future holds if I would need to repower. I know locally one owner who has repowered with twin yam 200s. I'm sure that is a perfect amount of power and balance. I would love to know if anyone has put one of the newer large singles on. The Merc 400R is 60lbs. heavier than my 2006 yam 250tur. I know the rating says, "300", but that's because larger singles have not existed until now. Given that the weight difference is negligible vs. older heavier designs, I'm sure the performance would be great.
