Question Bernico 21 - Evinrude V8 300hp

Hi guys,

I'm still looking for a 21ft project within my budget. Next week I'm finally gonna go to Holland to take a look at that blue Phantom 21ft hull....

In the meantime : Following boat is for sale : Bernico 21ft with tuned Evinrude V8 300hp. It's equipped with all the goods, trailer included. Boat is known as 'Tazmanian' in Belgium/Holland, it's ready to race in f1 & f2. You can find pics below... Maybe someone knows this boat ?

There seems nothing wrong with it, but it's for sale for a very long time now. No info on how it handles in corners and acceleration. My biggest concern is the engine. slightly tuned, 40-50 hours since rebuilt. Rebuilt done by Nico Bertels himself, with invoices as proof. Never raced. It should do 150km/h = 93mph.

I would like to have a good idea of the fuelconsumption.
I guess it should be double the V4 I'm running now ?? How much can this "light tuning" (280->300hp) affect the fuelconsumption? I read somewhere these V8 's were taken out of production because of the outrageous fuelconsumption... They are also heavy, but should be ultra-reliable. Don't know if all this is true... I'm thinking of putting an EFI 2.5 on that blue 21ft Phantom : How would the fuelconsumption of the V8 Evinrude compare to a EFI 2.5 260 or 280 ?

As always, every comment is appreciated !
T.

You said every comment is good?

Please don,t get this wrong ,before I start something here.

It will never run 150 km/u.
What prop is mounted on?
It should be a 30 pitch to come close to those speeds.
I,ve had a 23 raff with a 300 Johnson ,some mods done ,and it topped 119 km/u.
power in stock form was +- 270 hp ,they were build very bulky ,and power to weight ratio is not so good.
As for fuel consumption at full throttle only ?
remember a two stroke uses about 10% of its rated horsepower in gallons an hour,(full throttle)assume it produces 270 hp ,its 27 gallon /hour,same as a 260 EFI-280EFI,but those weight almost half of it.

What you could do is :take a GPS ,step in and you will found out.
If it is indeed running that speed ,buy it and go racing .

Yeah... you're probably right on the speed. I saw it advertised on different occasions... And I remember a "sudden drop" from 150km/h to 130km/h.

Only info on the prop is the picture. Looks standard Raker-like...
Also, thanks for your fuel comment, didn't know that 10% rule !!

Anyone else wants to share comments ?
T.

PS : Are you the Bernico 26ft cat owner in Holland ?

Yes I own one ,there is another guy who owns one also here.

The big V8 two stroke is not so relaiable ,mine threw a rod through the block.
I know from a few guys overhere that has been use the 4,0L ,s also that they tend to break so now and then.

Are you familiair with skiracing?there is a guy in Belgium that uses a 3,6 L omc block in a Z drive set up in a 19 ft Bernico.
That boat rocks.

I always thought the weak link on the V8 OMC OB's, was the lower unit, particularly the propshaft. I think there are hundreds of propellers, with half a propshaft in, sitting on the ocean floors oround our shores.

That's one great looking boat you have !!. There's been one for sale on the internet for quite some time now, think it's also on the Bernico site...

I'm not a ski-racer, just recreational enthousiast. Doing some wakeboarding and waterskiing on the Schelde river in Belgium at www.costazela.be One of the boat friends over there is Frank Meirsman. Maybe you know him. Owns a white/blue 19ft Bernico 2.5 280 EFI 165km/h named 'Ghostbuster'. Madman! He 's a driver in waterskiraces, also in Holland. Also races twins I believe.

Don't know the 3,6 L OMC Z drive guy... sadly enough
Maybe this can ease the pain : this ad showed up since yesterday

Thanks Jon ! Now I come to think of it... I saw some Evinrude V8's at the club in the past. One tuned upto 400hp (or was it 480hp??), which drank fuel like no other... Another one had some mechanical failure. Nico Van Ackelyen was testdriving it to check the problem. I was told (somewhere on the forums) the weak point of my evinrude V4 was also the lower unit. I guess it runs in the family, ey...

Conclusion : Evinrudes V8 = heavy, fueldrinking, and unreliable ?

Guess I should stay away from that Bernico 21ft then...
It's currently for sale for 8000€, price dropped from 8250€
Think I saw it sold in the past for 6500€
Currently highest bid is 6500€

This is not relevant for this thread, BUT On the Deauville Ralley with Twin 300 promax engines I averaged 66 gallons per hour - or 33 gallons per engine per hour!

I have 4 V8's hanging in my barn. Dont know what they consume, but they ARE huge and sound mean, maybe they're already broke, but i have lots of spares ;-)

Do they turn many rpms safely?

That aint a 300 v8 in the picture, thats a 225 v6, or an older 235, it certainly aint the v8 though, it has the wrong midsection for a 20" v8...

I already told him that 2. I think its a 235 v6. My hoods are way taller than the one on that boat.

V8 midsections are much stouter.

I'm cutting mine (from xxl to 15inch, open exhaust), welding them back together is hell because they are that thick and huge. Alu is a great conductor of heat (7-8 times that of steel) and the bigger/thicker the piece gets, the more difficult it is to weld it.

V6 are much smaller and look more elegant, just like this one.
