I have the same boat and ballast as you and have upgraded to the acme 1847 and couldnt be happier... Its like a whole new boat...The hole shot is much improved when getting up esp for slalom and the prop just handles the weight better... I went w the 1847 bc its supposed to be a bit better on gas for long trips and as I have some... Other guys run the acme 1235... There are tons of threads discussing it...
