Re: Repower from volvo engine?
An interesting question.
Pull the h/x and take a close look at the innards. Just because something is "original" doesn't necessarily mean that it's bad; you can clean out any calcification, and may be surprised to find that it's perfectly acceptable. You could either buy your own RydLime and clean it yourself, or take the tube stack to a radiator shop and have them do it in their boil tank.
Ditto the suspect injector. Pull it and have it pop-tested at a diesel shop.
Engine mounts and exhaust riser are fairly simple fixes.
I'd think you could do all of the above for well, well less than $5k.
Don't forget that a repower is probably going to cost you at double of what the new engine price may be. In addition to the engine, there's all the rest of the stuff that may no longer fit (exhaust hose, muffler, prop shaft, transmission, prop), possibly having to modify your engine beds, material handling equipment rental, labor for anything you sub out, etc, etc.
I'd be inclined to set aside (or start contributing to) your own repowering fund. If the Penta dies, replace it. Until then run it 'til it breaks.
All the best,
