What do you do if you throw a rod?

There is a boat that i want to buy and it is great condition for cheap. It's cheap because it has a motor with a broken rod apparently. It is a Yanmar 22HP engine. That's all i know.

Where do you guys buy rebuilt engines?
How much should i expect to pay for a rebuilt engine?

So far my research suggests around 4-7K for one but wanted to know if any of you had any experience shopping for motor replacement.

The boat is 1981 37' Seidelmann Sloop

Well kind of depends on where you are. Might want to mention what country you're in. Engine prices and what's available vary a good bit in different parts of the world.

Re: What do you do if you throw a rod?

A lot of people in the US really like the Beta Marine diesel if you have to repower. I think $4-7K may be a little on the low side if you're replacing with a similar size engine. Might be able to come in close to $4K if you do the work yourself go with a used engine. Could easily go $10-12K if you go new and pay a boat yard to do it all.

PLEASE don't pay $7k for a rebuilt engine -- or even $4. Please think about this -- diesel engines survive a very long time, and then they impale themselves and die.

I have friends who bought a rebuilt engine. Then, less than a year later, they bought a new one. For $7 you can get a new , 3ym 20 hp Yanmar. Installation would be about $3k here and you'd be set for life.

For that size boat -- it would only be a little more to get a 30hp.

high efficiency 20hp electric motors are about $400 brand new, and require no maintenance.

But then you wouldn't have the charging ability for the batteries.

Can they push a 37' Sidelman -- against a strong current and/or opposing waves? That's not a small boat.

When you add the batteries and the solar panels and wind gen or internal combustion powered generator and the controller and the wires and the batteries and mounts and connection to the shaft, it costs a LOT more than a simple repower. a LOT more.
That may be the single most misleading statement that I've ever seen on sailnet.

Re: What do you do if you throw a rod?

I just removed the offending rod, piston and lifters. Ran fine for a year or so. Kinda loped along like a Harley motorbike. It was a four cylinder Kubota. Plugged the crank oil holes with a safety-wired screw. Stuck a fuel return line on the injector line.

The beta marine 30hp diesel engine is 300lbs. :eek
It can't be easy to install such a beast. Crane?
My 50hp outboard was 200lb, I could barely move it.

Re: What do you do if you throw a rod?

Installed my Beta 38 by myself ... no help whatsoever ... in remote Palau ... while at anchor ... from a rubber dinghy ... minimal tools ... took a couple of days ... no big deal. Friends at the YC bar helped me get the engine from the truck to the dinghy. Removing the old engine, cleaning and painting the engine room took weeks.
