They are fine if looked after. There was an issue with the engine to gearbox drive splines on the early engines where fretting could lead to a loss of drive but this is well known and so most engines would have received attention however it is worth checking,. This wasn t so much of a problem if fitted to a saildrive as the flexible prob hubs absorbed torque variations and acted as dampers.
I think an improved starter motor also came on the scene to improve starting. The usual starting problems especially in the USA seem to be due to folk being unfamiliar with the cold start procedure which for some reason was ommitted from the operating manuals of engines sold in some parts of the world though the system was fitted to the engine.
There was a 2003 T engine of around 45 Hp which was often fitted where the turbo was not required and so would foul up prematurely. These can be more of a problem.

cold start procedure for Volvo Penta 2003
I have trouble cold-starting my VP2003. I've resorted to shots of ether, which isn't a good solution. Tell me more about the cold-start procedure. I haven't heard of this and there's nothing on this in the manual I have.
One suggestion has been to install a glow plug. Is that a good idea? If so, where do I find the proper glow plug?
A compression test a few years ago was ok. The engine has been lightly used.

The Volvo cold start procedure is:
In neutral, set the throttle to full speed. Pull out the stop cable and then push it home. Reset the throttle to about about quarter to half speed. Then crank the starter motor.

Switch ignition on first though.

I have the 28hp installed and apart from the normal engine problems there are the splines on the drive shaft to look at, easy to remove the box and check, because the shaft only engages part of the drive so some splines will look brand new and if your'e unlucky the drive part will have deformed to nearly points instaead of flats, can easily be modified for abour £500, there are several companies in the UK that do the mod. compression issues are common on these but can be easily checked with the right kit. Cold starting is also an issue if the start procedure is not followed, luckily I am in the med and rarely have this problem but UK boats will need to use the start procedure. Check the intercooler tubes for blocking, they are very small tubes that get fouled up but the end cap is easily removed and a coat hanger, or similar (wire typre) usually does the trick to free up any gunk in there.
good engine and has not let us down (yet.!!) parts are readily available, there are a couple of suppliers in the UK and stock genuine and pattend parts at reasonable prices.
what is she going to be pushing along?

Doug, try and stay away from that stuff, I have seen lister, cummings and petter engines that become reliant on it and will not start without it.........not good

I would suggest you do not back off the throttle as described above by this amount as there is a serious risk of untripping the cold start detent in the governor linkage. It is much better to readjust the throttle as the engine catches and hold at a fast idle.
I am surprised how many manuals do not mention this procedure which sets the fuel pump governor linkage to deliver extra fuel until the governor kicks in.
If you move the throttle to zero before starting then the cold start will unlatch and have to be reset.

No glow plug needed if the procedure described by others is followed. If problem persists, then check compression values again. If low, take the cylinder head off and grind the valves in. Can make your engine seem like new again. Look here for the manual which explains all. http://members.dslextreme.com/users/j40ed/volvo_penta_2002_worksh.pdf
