F1 300 efi

Anyone know anything about these

http://www.boatsandoutboards.co.uk/view/F148051/

Seems like a bargain to me? Are these the same motors that they run on the inshore F1 boats??

If it's a true F1 and done 4 hours it needs a rebuild.

If it is, it's an old F1 engine. No team/driver has had a 2 litre engine for many years. If I am correct......

2 litre engine, you had to rev it over 11k to make max hp.

a friend of my runs his 2.0l F1 @8500rpm on pump gas. Altered cilinderheads offcourse. I can assure you it still delivers enormous power.

When run @11000rpm on avgas, I thought it could do 15h and than a rebuilt... ??

i run the same engine on my bernico 19S.
the engine is bleuprinted and tuned,with altered cilinderheads (26cc) to run on regular gas instead of racing fuel.
rev limit is 8500rpm and it still delivers 280+ hp.
with the racing fuel cillinderheads it needs rebuilding after 15-20 hours.
only the hours above 6000rpm count for rebuilding !! so ive been told by one of the finest tuners of merc engine's in belgium.
i havent got a gps reading yet but the speed should around 80-85mph with a 19pitch 4 blade mercury offshore (vensura) prop

btw!! if anyone knows who selling this engine?
ive maild to the person 4 days ago and havent got any answer yet

with a 19" pitch prop and a 2:1 box and 8500rpm. you will be running about 65mph you,re going to need about 12000rpm to get to 85 with a 19" prop

I was in the boat while doing about 80 to 85mph @about 8500rpm... Prop was a 19pitch 4 blade

=> Think you guessed the gearbox ratio wrong mate....!
I know it's a Merc racing gearbox but I don't know it's ratio... (and I'm too lazy to calculate it... had a rough day )

A 1.62:1 ratio with 10% slip would be around about 85mph.
