Presuming you were looking to buy a used boat, which engine would you rather
see in her:

Remanufactured Perkins 4-108
New BetaMarine 1505
New Yanmar 3JH3E

These are all adequate to the job of pushing a 16000 # boat at hull speed,
so the question is one of your personal preference.

Thanks in advance,

4-108 for sure

We just finished puttind back in our 4-108 after rebuilding. I am happy with
the engine but. If we would have been able to afford it(twice what the rebuild
cost) I would of gone withe the BETA. Not the 35hp, thats too small for us,
but the 42 would have been perfect. Their job of marinizing the Kubota is top
notch. Love the Perkins but, It would be nice to have a more modern, quieter,
simpler engine. That said the new Perkins runs great.

Perkins. Forget those high rpm Yanmars...

The only hit that I know of about the 4-108 is that the operator's
manual introduction for bleeding the fuel system starts out with "For
the operator who is unfortunate enough to run out of fuel," and ends up
with "If this doesn't work, call for professional help...You do have a
working radio and did remember to pack some flares, didn't you?"

It's a real dog to bleed.

Lower rpm = longer life
Higher rpm = shorter life

The Perkins 4-107 in my sailboat takes less than 10 minutes to bleed.
The electric fuel pump between the tank and Raycor filter make it easier to
bleed. I leave the pump turned off except for bleeding.
As a bonus, if the fuel filter gets clogged, enough to cause the engine rpm to
fluctuate, you can turn the elec pump on, and restore adequate fuel pressure.
Before replacing a rusted fuel tank, the filter would get clogged and cause
problems. When motoring into the wind going out an inlet, I would turn the pump
on as insurance. Now with a new tank, I just use it for bleeding.
Don't let the feer of bleeding a Perkins influence the choice.
"Run it slow, run it long"

I put an electric fuel pump on my 4-108. It's the pulse type that
allows fuel to be pulled thru it when it is off. To bleed I turn on the
pump, crack two or three fittings and I'm on my way.

Not being personally familiar with the other choices, all I can say is
I've had a 4-108 for the last 5 years and it's been bulletproof.

It's never taken me more then 15 minutes to bleed mine, and that was the
first time I did it. Now that I have it down to more of a "science" and
can do it in under 10 minutes. And now that I've installed an electric
pump on it, I can bleed it in around 5 minutes.

I am surprised by the nearly single-mindedness here for Perkins and not a
mention of the Yanmar. In other venues I've been hearing negative and
positive views on the Beta products; some think the Yanmar vibrates and is
too noisy, but there have been no complaints about reliability or
suitability for the service.

Thanks everyone.

I have lived with the 4-108 for about ten years (twenty years ago) and
took the Yanmar's big brother, a 4JH, around the world in our Swan 57,
Swee****er. I'd pick the Yanmar in a second.

Among other things, a 3 cylinder has inherently less vibration than a
4. (In a three, the pistons are 120 degrees apart, while in a four,
they are 90 degrees apart, so that when one hits top dead center, its
mate is at bottom dead center.)
