Basicly there's not much difference between the automotive and the
marine versions of the engines. With exception that the I/O people
will select the heavier built engines that are used in pickup trucks
(thicker block webbing and 4 bolt main bering caps, Steel crank
shafts) but outside of that not much. Oh, the marine versions use a
different cam shaft than automotive and thats only to put the maximum
torque in a more suitable rpm range.
I run my 3.0 GM 4-cyl. at about 3300 RPM and the 350 GM v-8 at about
the same rate. Get up on plane than back it down to maintain the
plane. I don't run wide open. except to get out of the hole. But
both engines are capable of pulling 4000 rpm safely and sustained

Install brass freeze plugs and you're done.
I had an OMC once. I bought a short block (chevy) from an auto parts
store, they replaced the freeze plugs (they sell a LOT to nautical
types), and as far as I know, that engine is still pushing that boat.
I sold it maybe 15 years ago.
From my experience, it's the drive trains that give most of the
problems. Not the engines.

I didn't have any problems with my alph1 on the boat with the 3.0,
that is, until I hit a stump.
The stainless steel prop hub didn't break loose either.
Now on my 350 v8 the alpha (228) is having a shift problem, but it
could be an adjustment issue. But not sure yet.
Anyhow, on the Mercruisers, I would suppose due to popularity, they're
are quality after market parts on the market, so even if a person had
to replace the whole leg, it's still not a real kick in the wallet.
Of course, thats hypothetical ?; >

I've had only one pair (twins) of Mercruisers and I can't recall
specifically now what all went wrong (although I prolly still have the
file here somewhere). But it just seems there was always some seal or
boot or some such going bad which allowed salt water where it wasn't
supposed to be and that's when things would go to hell in a hand
basket. These were 4 cyl engines, 120hp each if I recall. They got
great mileage. But when those drive units aged, it was always
something.

Yup. Point well taken.

Depends on the boat, the demand for the boat, and its condition.
I sold my 2003 Parker 25' rig in 2007 for only 10%% less than I paid for
it. No broker, either. I wasn't hurt by the fact that between 2003 and
2007, Parker raised its price for the same model boat by nearly $20,000.
