Man hours to replace Volvo engine?

Does the same hold true for 290 Dp with 431b's?

I was under the impression that should it be needed the engines could be changed with the boat in the water.

Seemed logical that you just unbolted it at the Bell Housing, what would be the repercussions of doing this?

Ian you can remove some engines if you can get at all the bell housing bolts but beware as you lift out the engine you can upset the rubber o ring seals and you then get a sinking ship!, while the engine is out the proper volvo way you cando all sorts of jobs as you have a free engineroom, like the exhaust pipe/ orings etc, you also chnage the waterintake hose and do a proper service to the drive, bellows, gearshift cable etc.
 
My KAD32 came out in exactly the way described by Volvopaul, so you have your answer in a nutshell
,
Next job for me is to remove the mercruiser engine starting with a seized hinge pin, unless anyone can tell me how to get the engine out and the transom plate off without removing?

Which pin are youn talking about, to take a merc engine out is easy.

Remove the drive, 6 nuts, 2 rams pull off drive with shaft.

Disconnect all parts from engine, undo coach type bolts on front feet, undo 19mm or 3/4 bolts at rear which go into transom inner plate, lift out engine.

I always take off the manifolds and risers to make more room first job.

Undo all cables wiring for trim switches etc label up, then undo transom shield bolts on the inside, push out outer shield which is still the whole assembly, easier to work on steering swivel etc if need repair on the bench.
 
Thanks for that VolvoPaul, if the boat was out of the water I would drop the drive off but it was just a thought that if the engine needed to come out somewhere there were no lift out facility's.

Hi, thank you for your reply, the pins that i am referring to are the ones under the trim sender and the trim position switch, we attempted to remove these to replace the bellows in April, but one of them was so stuck that the special tool sheared off,
it is a mercruiser 485 engine with Alpha 1 drive which we are removing, it would make the job a whole lot easier if we can remove the engine and transom plate with the bellows housing still in place?
 
Mercruiser engine removal re Volvopaul

hello, undo 19mm or 3/4 bolts at rear which go into transom inner plate, lift out engine.

Paul, do you mean the two that go straight down or should i be looking for some that go front to back/? thanks

The 2 that go down.

If you have sheared the 14mm splinedrive bolts id warm up the alloy casing, it will then free off as alloy expands quite easy, then drill a hole in the middle down the bolt, insert a good quality easy out tool.

I wouldnt go down the road of takin out the engine just for the sake of one sheared bolt.

Another way around it is to cut through the bolt with just a single hacksaw blade and remove the gimball housing, you can then see the sheared bolt easier in the transom shield.

Thanks for the answer,
I am not taking out the engine to replace the spline drive bolts. i am re powering with KAD 32, but i was unaware that I could get the merc engine out without removing the Gimball housing,
I feel happier now with your explanation so will start tomorrow now that the shed is finished,
