I've re-read my post and for the life of me I can't find where I said I was anti-boat. Judging from my experience and observing the little use boats near me get, it makes sense to rent. YMMV
Well, 'anti owning a boat' then. That's perfectly fair; you're allowed not to want to own a boat. My point was that some people do smile

Some people will take the plunge (not literally!), buy a boat, own it for a while then decide it's not for them. But they got the box ticked, curiosity sated and can try a sports car etc instead.
I am an anti ownership boater and I own a boat!

The reality is that, at least around here, you cannot hire a decent boat.

Okay, my prop was changed during the week. Honda didn't do the same size, so it is a slightly larger one.

Now, between 2-3k revs, the boat vibrates. To a point where the fender rails shake.

Is this likely to be a faulty new prop or further damage?

Eh? Honda should be providing the correct prop with such a new engine and an Engineer (marine) should make sure that it is correctly sized and fitted. Confused?
My old one is going back for repair, when swapped back I will see what is causing it. But what are the chances of a bent shaft?

The original prop is beyond repair. It should have been replaced with a new one with the same pitch.
As above, it is being repaired.

The marina has said they will swap it back when it arrives. But, if it isn't that, they cannot look at it for weeks. Which doesn't delight me.

A new aluminium prop is less than £200 and 10 minutes labour to change.

I’d have thought that would be the best solution.

As I said above, a direct swap was not listed apparently. Only one smaller or larger than OEM.

I don't suppose you noted down what size prop was on it originally? If you have, or if you can find out, then I can have a look on Monday in the Honda books to see whats available as well as what is in stock. It certainly looks like its a Honda prop rather than an aftermarket one, so don't know why a direct replacement wouldn't be available.

As for the vibration, it is possible that you have bent the shaft. It does take a fair knock though, and usually the ali prop is the weak link. The easiest way to check, is to see if there any change in the distance between the gearbox and the prop. There's usually a little step in the hub of the prop about 10 mm from the gearbox, so as you turn the prop it should be easy to see if the closing or growing. If its staying the same, then the shaft is straight. If not then the shaft is propably bent.

You may be best ringing the dealer you bought the boat from and seeing if they've got a prop. If they're a Honda dealer and fitting Hondas to Jeanneau, then if Honda really have stopped doing the size prop you originally had fitted, then they will have had to find an alternative. As Jeaneau dealers we get given a list of recommended prop sizes that they have tested for each model, engine manufacturer, and engine size. We dont just put random props on and hope they work.

Also changing a prop isn't a bad ability to have. I just use a 27mm socket on a 1/2" ratchet, but you can get dedicated wrenches.

https://www.bottomlinemarine.com/prod_cat/P_quicks... this one even floats!

You'll also need a large pliers to straighten the split pin, and possible a bit of 4x2 to jam between the prop and cavitation plate to hold the prop still. It's held on with a castellated but, so nip the nut up with the wrench, look to see if the hole in the shaft lines up with a gap in the nut, if not tighten the nut until the next gap lines up with the hole.
Gazza thank you. I may take this on myself - not that I have time, but the marina is pissing me off.

That's all very well and good but this a new boat which is presumably insured, so why isn't this being dealt with by the insurance company? LB doesn't need to start pulling props or measuring shaft alignment, just leave it alone and insist the engine is repaired to original condition.
I don't claim on insurances, usually. Certainly not for something trivial.

In a way the marina might be the last people I'd trust - you're a captive audience; they know you're a beginner and might be tempted to you fob you off. They might not know that you're plugged into a rather good info source. When the amber bullst lights starts flashing, then with your brains, it might be flashing for a reason...
There is also a side issue.

When in the boat today, we noticed on the plotter a track that showed our boat on an island in the marina. It showed a course directly onto an island, and it isn't something we have done.

If I've guessed atthe right marina the the Op is in, then the marina themselves are a Honda dealer. So yes a captive audience. We do have problems going to many marinas around the country to do warranty work because they have either in-house engineers or on site contractors that they favour and we usually have to pay to do work on a customers boat.

Op, is the position of the island where the boat pay have been hauled out to to do any work? Chartplottrs sometimes do strange things when turned on or are delayed in getting a GPS fix. They can draw a dead straight line from the last known position to the new position.
It's a dead straight line from water to island.

And no, that isn't where they would have repaired the boat. It's an uninhabited island. If the plotter is telling the truth, the boat didn't turn into the aisle and continued into the island.

When a chart plotter or GPS is turned on it takes time to acquire satellites. The more satellites it sees the more accurate the location.

If the startup location (with few satellites acquired) was inaccurate was on the island and then the location became accurate when more satellites were acquired the chart plotter would record a perfectly straight line between the two locations.
I haven't delved into the plotter. Is it possible to view route by date? Garmin it is.

On the dealer - just because they're a Honda dealer doesn't make them good. My local Jag main dealer is the last place I'd take my Jag to - they usually break as much as they fix!

On the plotter/island issue, I too suspect a GPS calibration issue - unless the culprits can actually drive a boat over an island.
Oh you have a Jaaaaag do you? Suspicions confirmed.

I'll take a snap of the plotter and post it up.

Only because Astons are too uncomfortable and Bentleys too big. It's a curse I tell ya.

IIRC you have on of those ass-engined Nazi slotcars?
I do, and I also have one of the above.

Here's a photo of the plotter.

Date/time stamp? Might help explain when it happened, albeit not who was at the helm?

Are you suggesting your boat was run ashore by unknown perpetrators?

Any news regarding the propeller replacement, as I'm sure you will have checked with the broker who sold the boat or Honda Marine UK?
I cannot work out if it's possible to display route by date on the Garmin. But I am wondering if it has been pranged, or if that's just GPS failing to get a location and making stuff up.

We are thinking of selling the boat.

The supplying dealer says they can probably get our money back.

We bought it to give us something to do during lockdowns and a period when we (correctly) predicted travel would be tricky.

The reality is, winter is coming, marina fees are due soon, as is the waterway licence. Next year, we've a child going through exams and in the summer sport will again consume our time. I also predict that travel will be easier.

So, is snow the time to sell?

If you can get out without losing any money and your sure you won’t be using it so much next year (I live in Newark and know you’re down at Farndon so know the river where you are, must get boring quickly) then I think you would be smart to get out even.

If however you think you might use it sufficiently then I can’t see you getting back in to the same boat cheaper for a while. I think prices will stay high for at least another couple of years.
A family breakfast meeting has decided the matter. If we get the right price we are going to sell.

Good luck w/ the sale. Tricky time of year to be selling as your buyer won't get much use for 6 months.
If you didn't get a sale and winter storage fees etc were going to be due anyway, would you keep it for another season?
Potentially.

However a broker called me on Friday unsolicited asking if I would sell.

I am feeling lucky.

Sell or list? But then again if he has a bit of yard space where he will store brokerage boats for free and generally keep an eye on them, what does it matter if you have to wait a few months for the cash.
He is telling me it's worth £5k less than the supplying dealer says.

Then he wants 7%+VAT brokerage.

I think you know what to tell him to do biggrin
The supplying dealer wants 8% +VAT.
