Propeller fell off!

[macattack101]

Hi all
On holiday up in the highlands and went astern with mucho mucho gusto to avoid hitting a buoy and no drive as the prop went for its own holiday. Thanks to my mate on his sib he rescued me and the prop.
The prop had come off over the nut and pin sliding off its rubber cush centre with no damage to prop or shaft.
The issue I have is that the brass lock thrust washer was not fitted as with it on the castle nut will not go onto the shaft enough to allow the split pin to be fitted by a country mile. The rubber Cush is fully in the centre of the prop. I have only recently put it on and been lucky that I have lost it next to the beach.

Photos below shows what was left


Photo below shows with everything fitted and the nut is just on





If I take off the stainless washer forward of the prop then it would fit but need advice please

Cheers

Not the right hub for the engine?

^^ What he said.
Make & model of prop?
Where did you buy it from?
Was the prop sold as right for your engine?
What do you mean by brass thrust washer - is this intended to fit over the prop to stop it coming off?
What fitting instructions came with the prop?

(If its a Flo-torq prop this shows what needs to be present:

The hub was sold with the prop from steel developments for Honda bf115 engine.
It could be the wrong hub which would explain all the issues.
The brass coloured thrust washer is in the picture with the prop fitted.
It has fitted in order :-
stainless thrust washer
hub/prop
brass thrust washer
18mm nut washer
Castle nut

I will get the box it came in out of the bilge in the morning and see if that will help else old prop goes back on for rest of trip.

As you've got the old prop with you - wise move - compare the dimensions of the two.

I've had a couple of props and hubs from Steel Developments and they have always been spot on. Julie is really knowledgeable and helpful and I'm sure that she will advise appropriately if you give her a ring.

If you can't get the pin on, you don't need the spacer (what you call a brass thrust washer.)

Had a similar problem replacing a prop on my F115; but the other way round: the new prop needed about 3/8" of space taken up, so had to buy a spacer to make up for that.

Doesn't say anything about why yours failed though.

Found the problem, there were 2 forward thrust spacers fitted which took up all the shaft space. One removed and all greased up with the reverse thrust washer fitted and boat clocked 35knots racing across to isle of eigg in brilliant sunshine and flat seas. Happy days

It looks a cracking day out there today.

We are heading to The Old Forge in Inverie on Sunday for a bar meal.

Don't go too fast into the harbour as I got a row.....was also told there is a charge for being over an hour.
You have to book for lunch as they only serve food after 6:30 which we hadn't so we had a quick pint.
Saw 2 dolphins on the approach to the harbour which was cool.
Weather has been fantastic all week at 25 degrees.
Have a good trip

*they are a little touchy about speeding in the harbour at the minute, its not long since a local lad lost his life when he ploughed into the pier at full speed in his RIB.

*the chef is coming in at 5 for us. It helps being a "local"
