How difficult if the two engines need removal to repair?

[Boater On Thames]

Just viewed an old 1995 Princess 480. Found engine oil leaking quite a lot. Also found the two engines outside a few inches is the fuel tank so there is not possible to see or fix the outside of the two engines without removing the engine. In this case, the only way to check and fix it is to remove the two engines. How difficult will that be? Feel not right if every repair needs to remove the engines. What do you think? Thanks.

What engines ? Straight six volvo’s or V8 CATs , normally all the floor will come up for access, unless the sump has to come of I would have thought most jobs can be done without engines being removed, even if some other parts need removal for access

Buy something else. Remember your last boat.

Expensive enough to find another boat to view !

@andy59 They are Volvo Penta TAMD72.

@Scala @superheat6k Not going to buy that boat as there are a whole lot more other problems such as windows leaking, etc. Just want to learn something more. Thanks.

All depends exactly what needs doing ?
If its the sump gasket or rear main seal , front main seal and the motors are pretty aged then removal might be best .
This also depends on wether the builder actually forward thought it through and designed in - ease of removal .ie access hatch‘s large enough and space over for a hiab jib to go .

Then there’s a shed load of “ while you are in there “ stuff not just on the engines like clean all the coolers , replace the mounts , replace the black pipes , replace the fuel pipes , replace the G box hydraulic pipes , replace the battery connects , re paint the bilge , Then ask your self what else can be moved now the motors out ….eg the geny ? The tanks ( Bouba s predicament ) .
Do the shaft seals need replacing ?

Really an engine out jobbie in terms of yard gear and time can easily end up a mini machinery refit .
For what something that started out trying to replace a weepy a £20 quid oil seal that’s been dripping for a decade? Ends up a £20 K job all in when you have finished.

Here is a vid of a boat were motor removal is pretty easy.The cockpit furniture is bolted down from underneath and can quickly removed to expose the hatches which are massive .Most FB boats the hiab goes through the rear patio doors , and some fancy furniture / galley etc needs dismantling .

A first timer at a boat show will be oblivious to the question you are asking …..mesmerised by the width of the owners mid cab , hypnotised by the IPS joysticks ,

If you want to stump the sales teams at boat shows you only need ask two questions ,
1 - what’s the dead rise ?
2-Show me how you get the engines out ?

As Scala says….remember your last boat!
I see you had the boat up for sale OP…
How did you sort the fuel tank issues you had…….?

Princess 410.
Leak in fuel tank.
First problem getting the boat out of the water.
Next finding somebody to do the job and them fitting in to their work schedule.
Both engines out and might as well replace the other tank as well and as the engine room is empty ,a wiring tidy up and paint job.
Took ages to get new tanks fabricated and nothing major could be done until they were ready and back in place.
Boat was ashore for at least 10 + weeks.

Went to see a 410 recently where a previous purchase survey had revealed two leaking galvanised water tanks that needed replacing.
Had the new owner replaced them as result of the survey, nope.
Still there with the split seams weeping gently away.
Suspect the cost of work involved put a stop to that.
All the bits you could see on the outside of the boat had been nicely polished and the interior like new pin , mind.

Just taken my two Kad300 a out my cranchi 33 endurance this year. 25mins for both engines out. DIY Job (other than the hire of the crane.

sunpad off, engines out.

about a week of planning and disconnecting/ figuring out what goes where but overall straight forward. Key of course was the fact thatit had been designed with being able to take the engines out in the first place!

Blue Moon ?

Nope.......................... a P 410 on our moorings about 4 years ago. Skipper lost virtually the whole summer. Hauled out and repaired at Medway Bridge Marina.
To add insult to injury the boat had have a gearbox replaced the following year, was cheaper to buy a new/secondhand unit than to have the old one rebuilt by that company in Queenborough.
