Hi all i have purchased a princess 32 gone to put new props on and been told that the props should turn in opposite directions but both my legs turn the same way is this ok and if not wot can I do to solve the problem

cheers topcat1
 
rotation

Does not make any difference to us both ours turn left handed, and we run straight as a die, no bother. Others will say they should counter rotate, either inwards or outwards but believe me you will be fine.
 
my family as had 2 boats both running left handed prop's.with no problem's with handling
apart from she will turn one way better then the other due to the prop swing.
And again when mooring up you dont quite get the back end to kick in when going astern.But you just get used to it ,so you no longer notice it.
 
just another point.
i believe that someone purchased the right to the enfield leg,and he is the only one who supplies the parts/labour on them(i could be wrong).so he more or less can charge what he want's.
i am sure i will get shouted down if i am wrong.

Yes the props should counter roatate (handed props), it will handle odd if not.
For better control rh prop to stbd ( as your boat should be), for above displacement speed rh prop to port.(lifts the stern at high speed)

I have spare second-hand parts to do this job if you need them, (selector cover and selector rod) but you need to dismantle the lower case and the selector cover. (not too hard)

Sonic supply the parts for mine as bob knowles is only interested in selling a new leg (and will want to take your arms and legs in the process!)
If you want parts / help, send me a PM
 
princess 32 legs

I have a Princess 32 0n Volvo 270s one of three in our marina.I have never seen a 32 with enfield legs as far as i know all 32s had Volvo legs some Projects had Enfields. I wonder if thay are not the original legs which is way thay are not handed.What engines have you if thay are the orignals thay will be Volvo 4 or 6 cylinder.32 is a great boat i have been all over the east coast & Thames in ours.Got cought in a 8 once scared the cra*** out of us but not the 32.
 
Don't know as 32's were turned out with Enfields, but early 32's had 270 legs, later ones had 280's. The legs were not handed, the props were. It was just a case of where the gear selector cable was connected that determined if the leg was a counter rotating one or not. Not all 32's were turned out with Volvo engines though, some were fitted with Chrysler Nissans and some with Perkins. I've also seen one with 2.5 Di transit engines and another with XUD9 Peugeot diesels, both almost certainly fitted to replace the petrol Volvo lumps. After all these years i dare say there's a good few other engine conversions been made.
 
Princess Legs

The Volvo 4 cylinder 75 hp diesels are Perguot xd190 engines as i found out when i refurbed the heads on mine.Perugeot head sets were a third of the price of Volvo,all parts are readily available as Perugeot .Volvo told me parts were no longer availabe.i have just phoned a fellow Princess nut he says pretty shaw Enfield legs were not fitted to Princess 32 only Projects.But thinks that if the props run both the same way you will lose quite a bit of power
 
Yep your right I have been informed it is a project 31 it has Perkins 4 107 and Enfield 130 legs. Will it do any damage with both props turning the same way?
 
Enfield - Princess 32

For what its worth my Father in-law has a princess 32 and it definately has enfield legs on perkins 4107 engines. It does look to good an installation to have been bodged and converted so we think it is original. I could be wrong.....it would not be the first time and no doubt will not be the last.
 
as stated before topcat no real problem's running the same handed prop's,our old fella's boat as had left handed prop's fitted from the 60's and its still going strong.
just the slight handling qurk's as i stated before.
you get use to it.
enjoy the boat!

the Princess 32 & project31 have the same hull i think i read Princess bought the hulls of marine projects then bought them out People often get the 32 mixed up with the Project 31.Yes i agree i dont think you will do any harm.Have a great time with your boat.
 
You can see a specification sheet for the Princess 32 at http://www.princess.co.uk/heritage-docs/Princess-32.pdf.

This lists Chrysler Nissan 100hp, Perkins 4.107 and Volvo 145/280 engine options. It is quite likely that the Perkins engine would have been supplied with an Enfield outdrive.

Although the document only lists twin engine options they were certainly available with single engines too. Other engines and drives were also available such as Volvo AQD21A and AQD32A. I have twin AQD32As and these have 270 outdrives.

In the early 70's a shortage of volvo penta drives forced the fitting of enfield (actualy Perkins mk2) sterndrives to the Princess 32's, by this time the Project 31 was also fitted with Volvo units as standard but had to revert to enfields.

I have also seen Fairlines of the same era fitted with enfields for the same reason.

As to the OP's question/ It will be ok as it is, but better if it were handed as it should be.

If it makes no difference then why do all the manufacturers fit handed drives?

I must strongly disagree on this one. I mean, it's true that extremely fast boats (and I mean it: 80mph+) can gain a little in top speed with props spinning in (r/h port, l/h stbd).
But, and it's a big but, even such boats are often rigged with props spinning out, because that improves handling. Even at speed, not just when maneuvering! For boats simply capable of normal "above displacement" speed, props MUST spin out, period.
And btw, props spinning in actually lift the bow, not the stern. That's in fact the reason why they allow to squeeze a tad faster speed out of a hull, AOTBE.

Yes I agree, props turning out is the best way in 99% of aplications. If both turn in the same direction then power/energy is wasted correcting the bias and this leads to a slower boat that uses more fuel and is harder to helm albeit to a minimal amount.

But on racing boats (High speed) with some hull shapes turning in can create high pressure below the hull and provide lift to the stern (like an aircraft wing works). the lift to the bow comes from the force prop thrust creates and these forces together reduce drag = more speed.
