Engine Lifespan

[PeteSmith]

Id like to know when buying second hand engines what constitutes "High / Coming to the end of their lifespan" and "Low / plenty of life left in them" engine hours.

for example would people class "Evinrude 225 engines" made in 2005 with 700hrs on them as "Early / Mid / or late in their lifespan"?

I understand this all depends on servicing etc, but all things equal what do you think?

I think a lot of this is down to personal view.

I would class 700 hours on an engine as Mid Life however if you were to speak to some of the americans that are running 20-30 year old outboards with several thousand hours on they would probably think 700 hours was relatively ealry in the engines life span.

What I think will be interesting to see over the coming years is how long these modern engines especially the 2 stroke DI's last in comparisson to their more oil hungry predecessors. Trying to meet all these modern emissions requirements I am sure will take its toll on the engines in the long term.

A lot also depends on how the engine lived it's x00 hrs use.......

Rib Voyages Etecs have passed the 1800 hour mark.. so 700 hours doesn't sound to much..

1800 hours on an ETEC or a DI used commercially? Perhaps, but trouble free? I seriously doubt it, if my experience is anything to go by!

Leak down test tells a lot.

To take the nail out when buying second hand engines, perform a head compresion test to see how much life span rests before an engine overhaul. Specially if the amount to pay is big, ask a engine service center to perform this test. Don't have at hand the optimum compression life span rates (pressure measurements) prior to overhaulling.

leakdown test is best, compression test next best.
