Volvo engines (For Crazyhorse) - Page 2

Yes I am a bit Strong willed at times and maybe a little outspoken so I will take your comment as tenacious a compliment.

So are you running two engines?

And what hull are they in,Im interested as we seem to be the only two ribs running the same engines on rib.net anyway.But with very different drives.

Im also interested to see weather we can help others who may be contemplating the same set up as if they speak to some in the Trade they will get what they want to sell em.

What speed will it do with those engines and drives?

Dirk Diggler · 27 January 2003, 17:27

JW, excellent choice of drive, I have experience of it myself but on a petrol engine, 8.2GSi.

The only problem I had was the mechanical indicator sticking when the boat was left in the water for a few days. Easily remedied, a wiggle with one hand.

They used to have a built in "weak link" between upper & lower shafts, broke it once due to operator error. No big deal, replaced in a couple of hours.

Well the good News is the Engines have arrived safely and it looks like all the electronics ,Radar,GPS,Navtex, 2nd station Chartploter etc are all there.

So far so good.

One engine, predicted speed ...I reckoned about 50mph, Volvo man reckoned 52mph after he did his calculations. The engine is going into a Humber Offshore Pro. Got the bare boat just over a week ago. The engine is due on 27th so it should arrive any day now. Just extended my garage as a boat house/workshop. All the steel, suspension etc., for the trailer, is here as is the radar, plotter etc. So, I'd better get welding and fibreglassing pronto.
Dirk, I believe the protection device is still part of the current drive. Is it worth carrying a spare? How did you break yours?
For anyone who might be seriously interested. My present boat will be for sale shortly. It's a 6.5 metre Humber, 200hp + wing + full electronics, 6 wheel trailer and lots, lots more. Will post it in Ribs for sale when I'm ready to sell.
So, Crazyhorse, you now know all there is to know.
Cheers,
JW.

FYI

All Volvo KAD engines on Duo props must have Stainless Steel props or you leave yourself open to the blades disintergrating as the alu props cant handle the torque.

SS ones give you extra speed and more fuel economy.

Not True

Volvo have only just started selling S/S Props with there engines - as standard- If you hit something HARD with your S/S Prop the prop stays Ok - and just smashes your gear Box- Alu Prop - Blades break - bung new ones on.
I always operate with Alu Props.

You Must be thinking of the Yamaha Inboard - they are the ones that the props cannot handle the Torque - my mates on his 5th

Errr no sorry Pete, I even have the Volvo memo to prove this.

KAD engines have so much torque they bend the alu props causing them to pit and eventually come apart, I have seen it first hand as it happened on my boat and also a Princess, luckily I caught mine in time the guy with the princess didnt.

FACT

Used daily - used commercially - 1800 hours later,No Pitting, No Breaking, Nothing wrong in any way with the Alu Props - Maybe on a different boat eg a Princess,(which is allot heavier) but not on either of the volvo's I have.
Given the choice would not want a stainless prop, as said more breaks than just the prop if you hit something - Maybe just different set ups for boats other than a RIB?

Maybe should not put your foot down so quick, then you will get less torque?

True RIBs are alot ligher so would not get this problem as much but I have SS props now so am not worried. Glad I had them fitted tho as I picked up a hesian sack which would have ripped my aluminium blades off I reckon.

We have a Stainless Duo Prop and by reading what you have said then aluminum spare is the way to go.This is good news as it will be cheaper. My next problem will be where to buy the Alli Duo prop for a Kad 300 at the right price?

Interisting posts re the Yamaha and although Mr P doesnt seem to have any trouble to speak off, I decided it was safer to go with Volvo,as also there international back up is very good and most parts available in most countries, although some of you have recieved bad local service.

Thanks Seafaryskie for your imfo as it shows the difference of oppinion based on others experience is very helpful and can realy be of assistance.

And we can all contribute differing oppinions and all providing the motorvation is one of help and not bloody mindedness.

Cheers.

Charles you may be popular with some people and you have some obvious good organising skills.

But Please dont try telling me what to do. I live by my standards not yours.

Charles · 28 January 2003, 20:27

Still cannot spell! You need a chill pill -much too highly strung.......

crazyhorse · 28 January 2003, 20:30

As I say I live by my standards not yours.

In your own personal opinion?

seafariskye · 28 January 2003, 20:37

Agree with you completely - take a spare out with you - Aluminium is fine - this seems to be an old wifeys tale about this prop carry on--- before anyone trys to disagree - it is proven with time and experience - the best way- surely.

The way Aluminium props are sounding - from some - hit a bit of seaweed, and they are knackered - Bol*~^ks springs to mind- have hit allot worse, and no bother at all.

TIME PROVEN - which is surely the best.

which is what this is about - the best engine, proven IN A RIB

Seafariskye, I will not ever listen to Bull##t and I can see neither will you.

Alloy props are standard issue on petrol engines and they do a lot more revs with the same HP.

I do wish people would be carfull what they say as far as advice goes, as you could loose your mate a lot of money?

There must be some people on here that realise this is a great opportunity to genuinly help each other, and not allow each other to go with the flow,Purchasing and running a rib for any length of time requires sound advice,and not a load of Bull,from those that prefer to take ,rather than give any genuine imfo or prefer to pm each other more than post.?

Thanks for the Imformation and my boat will be a better boat.

And its a good un I promise.
