I have a tired original 3GM30F also in a J/35. Do you remember who you got it from? This seems like a simpler way to go than the newer Yanmars, but a Beta is looking pretty good at the moment.I got a rebuilt longblock 3gm30 for my J35 from some outfit in MI about 9 years ago.. 3200 shipped to MD. local yard put it in for 750-800 bucks.. it's still going strong.. thru a rod in the old one down near Solomons and it got me home on 2.. had to keep dumping oil in it though.. went thru a case.
The Hoye Tractor site used to have you put in the Yanmar part number and it would give their part. I just looked and now there is a marine engine page then choose your engine. Since it's Chinese products the prices maybe affected by the tariffs going on if you are in the USA.Any parts cross reference? I looked and looked and couldn't find any. Whats a 3GM30F in tractor speak?
I don't think you understand what I meant.I'd say that's bullshit. When you're dealing with the stressed rotating components (pistons, con rods, cranshafts???) you can't just pick up something that looks right and "grind them to fit". Things like these have very fine tolerances and have to deal with increase in dimensions as temperature increases.
I have nothing against going to a bearing shop and buying generic lip seals and SKF bearings for my Yanmar raw water pump - but what you are suggesting is nuts.
While what you're saying is true, I think the problem with old Yanmars is what DrewR said. You won't find a cross referenced parts list anywhere. I posted a thread on this a year or so ago and no one had any idea. I had hoped maybe an old timey diesel mechanic would have made up a list with cross referenced Yanmar industrial/agricultural part numbers, but no such luck.I don't think you understand what I meant.
For example, there is this company called BMW. Most people know about them because of their automobiles. Do you know that BMW has a marine division too? The BMW M20 block series was available in BMW cars, boats and Lincoln (yes, Ford, Lincoln, Mercury) cars?
Companies like Bosch, Siemens, Valeo, ZF, Getrag, Lemforder, etc.... All they do is make parts --or "stuff". VDO makes great gauges --and you can find VDO gauges on all kinds of cars. Think about Brembo brakes. How many current car manufacturers tout "brembo brakes" in their advertisements.
Some company makes rings and Yanmar buys them --but so does John Deer or Kohler or BMW. I could also be totally wrong. Yanmar could do everything in-house... But I highly doubt it. Half the engine parts in my car can also be found in a Range Rover, Lexus, Nissan, Some Fords and Subaru. (maybe more that I don't know of)
That's Alf Holzer in Bayfield, WI. Rebuilding marine diesels is what he does, all the time. Most of the engines on this page are his remans.this is old email I found... that's all I have for the engine source...

Here's a 2GM20F rebuilt for $4450 + core. Might reman yours for less. Presumably he has his supply chains pretty well sorted. Also does Volvos, Universals, etc.
Good to know! We have a doubtful MD6a we're not sure what to do with, & a Holzer reman (Yanmar) is a serious option. My instinct at this point is: if we're gonna put money into engine work, put it into something other than a raw water Penta with a cracked block.and I will say he was a pleasure to do business with...
