Turbo Advice Please

I can't see the point of having them rebuilt just to save 30% of the cost of a new one. In this case, I'd give it a clean, refit it and budget for a new one in a few years time.

I'd second that personally. VP ones seem to be rather close to the salt water and corrode quickly and you end up chasing your tail. But as in my original post you'll only know for sure how much it's gone with a boost check. Volvopaul is correct a new one will make a big difference but I also wouldnt want to be changing every 2-3 years to save that 0.5 bar of boost. YMMV

It's not new. However, I found a local turbo place that is familiar with this model and I am going to let them take a look at it for possible refurb, so maybe it'll become as new!

All depends on time and cost - as usual... Figure I may as well while it's off and the boat isn't going anywhere.

The manual says to leave bottom oil line off and run engine with starter motor only with stop solenoid off. Did you go that far or just fill with the syringe?

Even if not new why wouldn’t you do such a simple thing as priming. Also suggest doing an engine oil change at the same time so you have nice fresh stuff going through. I didn’t run the with starter motor only because on my KAD43 it’s not obvious (to me) how to turn off the stop solenoid.

Also for interest I replaced mine after 15 years of corrosion, it only has 400 hrs on the clock.

Also I went new after a few horror stories on here of some refurbs blowing

any record of increased boost / speed with the new one ?

Just clarifying condition. I agree, why wouldn't you. But dripping some oil into the feed is not exactly the full engine manual procedure. I was wondering how close people actually got to that procedure.

Oh yes!
The worn turbos (and my overweight boat due to toys) really struggled (sorry no data)
New turbos totally resolved the problem.
I only did a pressure measurement after fitting the new units but from memory I got 27psi which was a little above the spec of 25psi (there is a temperature correction graph so I only guessed at air input temp which could account for my above spec result)

The old elevated EGTs leading to exhaust turbo tip burn out .
Overloading , bottom fouling , stern gear mis hygiene .......you know the rest .

Another VP turbo thread .

It’s not your egt that damages the Borg warner units like this it’s the fact that on a sterndrive boat the waterline is up the exhaust pipe about 2 or 3 inches away from these parts , the casing just suffers from pure corrosion and nothing else .

Shaft drive versions don’t suffer as quick as the have 6ft or more of rubber hose pipe to keep it away from salt water levels .

When taken for repair the whole exhaust housing is shot blasted to give an indicaction of the severity of corrosion usually around 3 to 4 mm dis from the housing leaving a big gap around the fan .

ive seen some really crude attempts to re manufacture the housing by boring out and fitting a sleeve , the last one I took to my local repairer absolutely pissed themselves with the repair and just fitted a new housing and fan m this company even trimmed down the fan diameter to fit the sleeve they fitted , no wonder the boat didn’t perform .

Makes sense as this is on shafts. Rough idea on refurb costs Paul? Fan and housing?
 
Case of boat with a VP 60C. 255HP
A turbo was removed and a turbo refitted , it might have been a new / refurbed or the original unit. Only the skipper knows.

First trip out. Fine while at tickover but a very short time after going into a fast cruise something thing got red hot and caught fire.
By the time the skipper realised something was wrong, it was too late.

4 new pistons and liners, all new bearings and complete rebuild of cylinder heads and valves.
Engine had to lifted to release con rods etc. A real pig of job.
All down to a faulty turbo and/or installation.

Clearance looks on its last legs perhaps. Probably as important is to have a smell at the bearing oil chamber. If it smells of burnt oil...send it off to AET. Great service. If you let it get too bad...you’ll need a whole new casing, the lot. You’ll be £1500 out of pocket then...instead of a few hundred quid.

100 boats on our moorings of all flavours .If it going to happen, its either already happenend, about to happen in the near future or has happened recently and is bring fixed as you watch..
Virtually all our members would rather die than spend money paying somebody else to fix their boat.
Easy to spot. Piles of dismantled boat visible ,some of it on pontoon.
The only expception would be those with the misfortune and lack of judgement to buy a boat with any of the big advances in boat engine control management.
This normally is signified by a white van parked in our car park, with a discreet VP decal on the side.
The white coated chap inside filling in a form justifing the Kings ransom they are about to charge.
He leaves the journey in his SATNAV memory, knowing full well he will be back , to fix the same problem.
He will replace something different this time and charge another fortune.
Experience tells him not to erase the journey from. his SATNAV.
Helpful advice always on offer. 10 different skippers offering 11 different solutions. 11 of them of them total .............. :)

Not bad at that price. I thought it would be over a grand? Tempting...

Aslo be careful you do not have the same engine as Mr Googler and you will need to check your part numbers match. I suspect your turbo is different as the kads have a smaller turbo with their supercharger design. I think your turbo is bigger.
