Formula 330 Outboard conversion
I have finally given the go ahead on the outboard conversion of my 330 SS.
I am sure there will be quite a few eyebrows raised on this one, but believe me I can not run inboards where i am.
Without going into detail , 33 feet boats can ONLY be moored in ocean salt water in humid temperatures and all year around.
There are hundreds of boats moored right next to each other so the electrolysis is rampant.
Fortunately , the very low cost of the transom/bracket work and electricall rigging work locally , allows me to sell the inboards and offset the cost of the transom and electrical work.
That leaves me now with the choice of outboards.
Not looking at beating the original speeds or winning offshore races, but hoping to be able to reach 50MPH or about with the inboards.
Now need to decide if it can be done with 2 x 250 verado's or if 2 x 300's are needed.
From my internet searches I have seen conflicting info of (hull extended bracketed) outboards versus inboard engines.
Anyone care to pitch in ?
All positive advise appreciated.
Thanks

You might want to start with just checking in with some bracket manaufactures just so see what is requried. Also do a serach on this board for Bracket conversions. Good Luck and I think you might need Triples to get that thing up on plane. I also think the 330 swim platform would need to be modfied otherwise your props will be set way back from the transom. Also if you look at the new searay they hide the outboards insde the boat where the normal engine woudl sit you might look at this option. I always like a project but I am not sure if this is a good one for the money in my opion but good luck.

thanks Boomer.
I have spent about 6 months researching online an spoke to all the usual bracket makers like Armstrong , StainlessMarine etc.
There are 5 boats here at the bay and they have all been converted adding fiberglass and setting the engines back.
All of them seem to hold up but not sure on the performance , i am already looking at 2 x F350 's...
On another note I am still not clear on the sterndrive versus outboard deal , there is conflicting info online.
To me the boat originally had 2 x 320HP sterndrives , so my expectation were that the much lighter 2 x 300's would suffice...no clear examples anywhere where a comparison has been done on game HP sterndrive vs outboard.
Will post pics when project commences...
