Not at all ... works good. Thats how I did my Superboat. Bought a 6" ran it for a while, decided it wasn't enough and added 4" .

The big hub wheel we talked about the other day ... does it have a flair ring at the back .. ??? If so, chuck it in the lathe and cut it off as short as possible. Big hub adds length to the gearcase (stability) and without the ring it won't add any additional influence to the handling.
As always, tell the princess I said howdy ... :thumbsup:
P.S. How does she like her new boat .... :leaving: :D
