We could speculate forever, but I think it's extremely unlikely it hydrauliced if it kept running throughout the 'spin', or whatever happened on that turn, it would be so hard to get any vasser oop 't' pipe whilst morta wer still alive like.

If I see Terry I'll ask abou the restart.

The importance of this to other V24 racers would be to find out whether the submerging caused the engine failure, or not.

Because IF you can stuff your motor as the direct result of putting the boat down into the water this way, (running or stopped) then theres alot to consider.

It always important to keep an open mind and let the facts make the case. Problem is; I am probably holding back the bits of evidence you want, without even thinking about it. Because I have used them and come to my conlcusions. I am no longer that open minded.

I spent the day with Cronky at the F.O.S, we talked about it now and then. He's the one who stripped the thing so far. I didn't look at the cam bearings but he said that all are totally unmarked.
The devistation without any trace of heat where it shouldn't be, the clean bearings including cam, no abnormal wear, means to me, it died quickly. The bits breaking out every where shows the chaotic force spreading out in shock waves.

Adrian was saying that three of the four pots damaged were on the same side as the dipping and the one on the other side was damaged as a result of the others, I didn't check through that stuff, its not my business.

Fair enough, let's hope whatever caused the devistation on Terry's boat doesn't visit too many others, it's an expensive game racing!

Water detection

Colin a mate at the marina said that water was found in the manifolds when they took them off over lunch today.

A.C confirmed this later.

I went and had a look in the heads.

Sure enough the port head, 3rd pot back, has a cleaned out port that is now rusting away, none of the others are in this state they are just lightly sooted.

Is it not a possibillity that the water entered the engine after the damage had been done. If the motor spewed it's guts during the race, then surely water could have gone up the exhaust whilst waiting or during the tow back to the marina. I would say thats it's highly unlikely that it would have entered whilst the motor was running!!!!

All IMHO of course./

Could have couldnt it.

The way the water / rust marks are in this Ex. port make it look as though water / some fluid went out at speed. Like streaks up a visor or windscreen. Its washed / eaten the soot off as its come out and left a P.H. balance that started the Casting to corrode in no time at all. Thats only in one pot though. The rod on that pot is the one that stopped the rotation, its stuck in between the journal and the block wall.

Two others snapped clean off . This Rod couldnt have hit them, its still in place. but the forward stretching of the crank may have knackered them. The way the gudgeon pins have been torn from the pistons indicates (to me) the diagonal movement forwards.

Any idea what the bores look like? (don't say 'round'!)

Boatmad investigation services

Of cylindrical origin.

Everything in the crankase region is lightly oiled.

I dont know that it will get pulled down any more for now, but shall keep an ear out for where it goes next.

HOW MANY INCIDENTS

ear to the ground rumors are that V3 had an alledged incident on the first lap which i believe is the one mentioned above, yet the boat went on for another 5 laps at least before it stopped, was there more dippings? or riser gasket failure which is also a popular prob.and would cause streaming like on a windshield and with a rough race like that there would have been lots of on off with the noisey pedal poss sucking back down the exhaust with the negetive off load compressions.

or just trying too hard to catch the ginger boat

What would one expect without a flexible link in the exhaust tween manifold and exit point through the deck on an exhaust that's 3' long or more!...summat's gotta give.....elementry engineering

Quite clearly if you prepair the boat correctly you should notice a smaller prob before it becomes a huge prob , several boats running this and last year have not had any leaking header gaskets .

Mmmnnn, interesting, but fixing a problem when it occurs, repeatedly, is foolish, when you could fix the reason it's occuring 'once'...Or even better, do it right in the first place, and not 'fix' anything.......all IMHO

As for the 'incident', if it ran for another 5 laps before stoping, I rest my case.
