Outboard Powered 330 SS
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 OUTboards.
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
Mike

I would go with the 300's, if you can swing it. This should be interesting to follow. I think I have seen a go-fast boat converted to outboards, but not a day boat, like the 330.
Post pics as you can.

There is not enough omph with 2 300s to make that thing jump on plane and do 50.
i would go for triple 225 or 250 Yamahas and never look back.
my dad has a single 225 yamaha that is 13 years old and has a good 4000 hours on it but hard to tell because the hour meter quit years ago.
Had to put a new lower unit on it a few years ago because it lost a shaft seal from a fish line wrap.
I had to rebuild the exhaust but that was because of a bogus year of component manufacture.
But all in all the motors are relentlessly reliable and low maintenance.
I would never hang anything else on my outboard transom after my experience with them.
Wheer do you live?
I take it you are somewhere over in Europe

Highly doubt 300s will push that boat to 50mph easily. I agree with that weight trips are a much better option. Basing this on a 30 scarab sport which is a much lighter boat than a 330ss running at 60 on 300s. That boat is 4000 pounds heavier than the scarab based on a dry weight of 9700lbs. Maybe a set of the merc 400s would be ideal for that.
