Any idea how fast this would go? :aaahhh:
 
It's reputed to do 138mph
 
Has it ever been seen on the water (at speed that is)?

Whose boat?
 
Martin Mainsbridge (online racing) It's been kept in the water at Ocean Village.

Everyone who I've spoken to who's seen it running says that only seen it run around 60mph!
 
Certainly better looking boat than the Aluminium cat that he had built back in the 90's - but how would you like to keep those engines running / fed?
 
There's a simple answer to that one! I wouldn't:aaahhh:

It's also reputed to be getting a new transom.

That boat rolled over about 2 years ago,it was laying at Extreme marine in Florida ,I bought 2 propellors from that boat.(15x34 cleavers 3 blade)
The owner was driving 90 mph with 4 friends aboard,and trimmed in too far,he wanted to make a turn ,when the boat rolled over,nobody gets hurt besides a few bruises(thats what I,ve been told)
At that time that boat was green,Larry Goldman ,the owner of Extreme marine said that the boat was sold to the U.K.
There was some damage on the deck and sides,and all the engines where under water.
I believe its repaired and sprayed in different colors in the U.S
but don,t know for sure.

I don,t think it can run such speeds,with 1,62:1 ratio at 6800rpm for the 300,s the propshaft is only turning 4197 rpm
with the biggest props available from merc 15x36 labs it should run 129 mph with 10% slip ,and 124 with 14 % slip,it could run 143 with no slip(theoretical speed)
Mine cat is having 16 % slip,with 7800rpm ,1,87:1 ratio,and 15x 34 pitch cleaver 3blade (lab finished)
I want more speed also,but having trouble already with accelerating ,and some more people in the boat.
I even think to buy a set 15x 32 labs to have stronger acceleration,and hope my engine,s will rev some more to maintain topspeed.

I have seen the boat in action, and anchored in Christchurch bay, according to the owner it does go over 100mph, im sure he said 130mph max, but i cant remember. Some friends of mine managed to blag a spin on it, all four engines were running, cant remember how fast they said it went.
