The curse of my old boat continues...

So, the old boat has been up for sale for a while now.
After all the problems we had, and replacing pretty much everything, a new outdrive and then a rebuild on that one, it's actually been faultless for the last Year or so.

Chap expresses interest from Grimsby, sees all the pictures, I shoot a few videos for him, we get some shipping quotes and he asks to come and see it if I'll withdraw it from sale on the strength of a deposit after viewing.
He's coming down on Saturday, and as he's got an 8 Hour, 500 mile round trip, I nip down Friday evening just to make sure that the outdrive is still attached and batteries are OK.
And, of course, the %$^%$ won't start.
Phoned him, he asked me to let him know if I resolved it as he still wanted and if I let him know by 11am on the Saturday he'd still head down.
Couldn't sort it in time, but an RCC member on seeing me struggling with it, leaped into the boat, started it with a screwdriver and diagnosed a possibly faulty relay.
Oldgit happened to be wandering past at the time on his way for a relaxing trip out in his boat, he instantly flung himself into the bilge armed with a penknife to try and clean up the suspected relay before diagnosing it as the definite problem and completely knackered. (thanks chaps)

New relay purchased, fitted Sunday morning and the buyer is on his way down. (yes, he's keen)
Arrives Sunday afternoon, spends a couple of hours looking over the boat, likes it, so we head off for a quick trip.
Up to the section of river where the speed limit lifts, the buyer applies full throttle, turbo spools up, engine singing sweetly and.... carries on revving to the redline whilst the boat stays put.
Slightly incredulously, I asked if he could have caught the button on the control, I take over and get exactly the same thing.
Up to 2000rpm, everything is fine, above that and something slips and all drive disappears.

Red-faced with shame and apologising profusely I apologetically limp the boat back to the pontoons, well aware that it's getting late and he has a 4 Hour drive back home...

So, couple of questions.

1) What one Earth could it be? outdrive is a Volvo 270, reconditioned by IVSS marine in 2014, then rebuilt again 9 Months ago when an oil seal failed and let water in.
Propeller is a new genuine Volvo penta item, 9 Months old with about 3 Hours use.
Is there a rubber buffer in the prop like a cush drive in a motorcycle wheel that's faulty and slipping?

2) The buyer is a really nice bloke, and despite me advising him that the boat is cursed and to go absolutely nowhere near anything with outdrives, is still keen on buying it if I can resolve the problem.
However, I really want to steer him away from outdrives and can't think what to advise him to look for.
He's using it on the Humber, with the odd overnighter to Whitby. It's going to be his first ever boat, he wants something small, <£10K, a bit of a do-it-all with a diesel engine and knows absolutely nothing about boats. Pretty much, exactly the same scenario we were in when we bought it as our first boat.
Only thing I can think of is a later semi-displacement Colvic seaworker but, they're scarce, and probably over budget.
Is there anything else out there??
Although he doesn't want a petrol boat, is there something with an outboard that would fill that brief? The fuel costs would probably be offset by not having the maintenance and lifting costs of an old outdrive.

3) What on earth to do with the boat?
It owes me about £14K, it was advertised at £7.5K no offers.
Do I sell it as a spares or repair project and re-advertise it at £4 or £5K just to try get the thing out of my life?
Or, get a BSS put on it, move it up to the non-tidal river, pay the marina fees and get a marina to broker it as a river boat?
On the non-tidal river, pottering around at 4-5 knots, it's never, ever given me a hint of a problem. It chugs along, sipping diesel at tickover due to the massive prop that it's running.
99% of the problems I've had with it have been during, or after, pushing the torquey diesel engine through the leg that was only ever designed for a petrol motor.
I guess that by the time I've replaced the prop or had the drive rebuilt again, got the BSS inspection and carried out the work probably needed it would be around £1K (wild guess, ballpark figure allowing £500 for prop or drive rebuild then £500 for fuel lines, inspection, new fire extinguishers, gas lines, labour etc)
But, by the time I've paid 2 or 3 Months marina fees and the brokers commission, even selling it at a high price, I can't see me clearing more than £7K or so. (where it is the mooring are paid up until the end of the Year so it's costing me "nothing" where it currently lies)
I won't do any of the work myself, this thing has broken me over the last 3 Years and I'd far rather sell it as spares than set foot on it again. I've actually developed a nervous twitch whenever I see the thing soiling the pontoons at the club, rocking smugly in the tide...

Another option would be to list it on ebay on a weeks auction, 99p start price, no reserve. The financial loss would be almost total, but the value to my mental health would be high!

Any advice, ideas, thoughts, a sympathetic smile with a cup of tea, very welcome...
 
Ah, the parable of the unlucky git! Quite normal for unexpected things to go wrong during a sales trip. I'd say it's the prop' hub slipping if they have the same rubber hub as outboards. Persevere with the sale as the new owner will never have any problems again, it's your luck that is the problem so he'll be fine. Speaking from experience here by the way!:confused:
 
+1 for the prop hub. Had it happen on one of ours on the last boat and took me a while to figure it out. Replacement prop and your potential buyer should be happy, particularly as it sounds as though you have been completely up front with him.

Not sure about your thoughts that the 270 drive was only designed for a petrol engine. We had 270s on our first boat, which had twin diesels.
 
If it's the hub that's spun,you don't need an entire new prop,you just replace the hub in your existing prop
 
Many thanks all, what I'm reading from this is to lift it out, set fire to it and walk away. Sounds like the best option :)

Apologies, I will calm down at some point...

Really appreciate the advice, logically, it can only be the hub, it must have been faulty from the factory.
I don't thing there's any point asking about warranty, Volvo Europe were completely out of stock when I bought it so I had it flown over from the states.
I shall give steel developments a call on Tuesday :)
Thanks again,

Chris
 
If it isn't the hub, it could also be slipping cone clutches in the out drive. Thing to is test with another prop if possible to see if the same thing happens.
 
Feel for you on this, have been close to there myself.
Must say I was thinking cone clutch also (assuming the 270 has one).
You have to forget what it owes you and concentrate on what it is worth and with stuff wrong that wont be much.
So see if you can fix it and go with the current buyer?
By the way when I sold my last boat recently the buyer mentioned he had found my posts on the forums about the boat, dont know if your boat can be cross referenced to your post but if it can a potential purchaser may not be encouraged!!!!.............

That was in the back of my mind, hence leaving the name of the boat out!
But, I did leave the potential buyer under no illusions, and did point out the amount of aggravation we'd had with it which, as far as I knew, was all sorted out.
i don't want the current buyer to have it, he wants to take his son out to sea on it and I just don't think it's suitable, or safe, for that.
Went to one of the non-tidal marinas this morning and had a long chat with the manager about the best way to move it forward.
I need to get it it sorted either way, but it looks as if the best thing is for it it end up with a BSS and live out a happy retirement pottering around on fresh water.

Plan is to put the leg in gear, raise it, then wait for it to dry out before venturing onto the mud and trying to force the prop round against the resistance of the gearbox.
If the nose cone turns with the prop, it's the outdrive. If it doesn't, it's the prop hub.
 
So, a small diesel engine like a KAD32 produces something like 375Nm at peak torque.
Running through a 1.95 gearbox reduction in the leg, I make that about 730Nm at the prop.
Let's be charitable and deduct 50Nm for losses along the way.

That's still 680Nm ... :eek:
How big did you say your biceps were?

Yep,I don't think turning the prop by hand will be a valid test,you won't be able to put enough torque through the system.

Take the prop off and give it to a prop shop and ask them to check it.
 
I did query that with the broker, he seemed to think it would be possible.
I've no idea what torque it does kick out at 2000rpm, I know it's rated at 140hp at 4000rpm so probably making most of its torque by 2000.
2.5 litre turbo charged, charge air cooled turbo diesel, I guess the figures for the KAD32 are probably not too far off. Either way, it seems quite likely that even with my not inconsiderable weight behind it, I don't stand a hope in hell of replicating what the engine is putting through that large prop.
Plan B then, mark the hub and the nose cone, repeat the run and see if they're still aligned?
(can you tell I'm trying my hardest not to spend another penny on this bloody boat unless I really, really have to?!!)

Thanks all,

Chris

So it is personal! I thought it was! Good thing I accidentally gave it a couple of hefty kicks as I scrabbled aboard yesterday to retrieve some tools :D

Ah, didn't realise that, although this is a turbo diesel and I'm sure the 270 is only rated for 130hp.

is this still the lancing marine set up??

Yes, that's the one.
