I use Wix filters from a truck parts store.

Re: Universal 5424 Diesel

EPA requirements will block getting parts from the tractor dealerships. Can't even get an injector anymore from them. Fresh news from my Kubota Tractor dealer and parts supplier. They said for every tractor replacement engine they have to prove to the EPA and Kubota the old engine is destroyed. Parts are just as hard to prove use.
SAY WHAT???

mtugrad1985 kubota engines are top. Issues with modern EPA requirements will block getting parts from the tractor dealerships. Can't even get an injector anymore from them. Fresh news from my Kubota Tractor dealer and parts supplier. They said for every tractor replacement engine they have to prove to the EPA and Kubota the old engine is destroyed. Parts are just as hard to prove use.

That said, there is an easy out. I just had this discussion today to replace my M5424. The M5424 is either the 922 or 905 block. (25 hp)

$25,000 fully installed by a top flight marine shop in Michigan, brand new Universal motor and transmission and all new goodies. They told me Universal won't allow a DoItYourself install.

$12,000 do it yourself replacement with the Beta Engine (Kubota Marinized by Beta), very nice unit.

Buy a full replacement long block from Kubota Industrial engines. $3700, approx.

order your replacement parts from the Industrial Engines dealers as well.

So, i'm going strip the old motor of the manifolds, heat exchangers, pumps, etc. then marinize an off the shelf brand new Kubota. And put in a thrust bearing and CV joint system, mounting the motor and the trans level, cutting down the stringers.

I hope that is not a lot of hours...I'm a week away from buying a '80 Cal 31 with 5424 that was installed as a rebuilt engine in 1999. 4700 hours on the meter and I'm hoping that included the original motor.

Sir, me kindly requesting spreadsheet for parts conversion for my Universal 5424 24 hp diesel.
e-mail is igor130@hotmail.com.
Much appreciated

Re: Universal 5424 Diesel

On the subject of gauges, it is de rigueur to bypass the ammeter in the instrument panel, as the Universal wiring is unable to safely carry the alternator charging current. This makes the ammeter rather useless.

I replaced mine with a voltmeter - much more useful

Re: Universal 5424 Diesel

Gee, for a 33 year old boat, 2,440 hours doesn't seem very high...maybe even a little light? 2440/33=75 hours per year, huh? Check to make sure the hourmeter is actually working. Realistically at that age the kind of use it's received is probably way more important than the number of hours...how does it look? Original or sixth owner? Decent engine maintenance logs or none? I have a 5444 with over 3,000 hours, and just finished redoing the cylinder head, replacing the "water flange" that the thermostat sits in, overhauling the heat exchanger, and replacing the gauges in my instrument panel.

I think the Kubota's are good little engines, and the Universal marinization bits seem okay too. That said, you have to be ready to do a little detective work figuring out the Universal/Kubota parts cross reference - search Google for "Kubota parts" and you'll get a bunch of hits (Kumar Brothers sells a lot of aftermarket stuff). Shops & mechanics used to working on Yanmars, Perkins and Volvos may not be enthusiastic to work on it, but they are pretty simple engines. How much of a DIY'er are you? I replaced three gauges in my panel with nice new Teleflex gauges that are nicer than the originals for $160, and it took maybe a day all told, including changing a bit of wiring.

One thing I learned is that compression and leakdown tests can tell you a lot. OTOH, my understanding is that the real value of oil analysis is tracking changes, so a one time test isn't all that informative. SOME of the marinization parts on these engines are getting pretty scarce (like exhaust manifolds), and even finding these parts used can be tough, but I think most things could be MacGyvered. Good luck!

Re: Universal 5424 Diesel

Lots of tractor parts are available for that engine (the non marinized parts) at deep discounts to the cost of marine engine parts (sometimes as much as 90% off). If you buy the boat, PM me and I will email you a spreadsheet with crossover parts numbers I have put together. There are some issues with decreasing parts availability (search for M-30 and heat exchanger for an example) but they don't seem too bad. 2500 hours doesn't have to be "HIGH" if the engine was well maintained it may have tons of life left. Frankly, the Hurth transmissions seem to be the biggest source of complaints I have noticed (I have had no such probs myself -- KoW). Look for smoke, it should probably run @2800-3000RPM at the top end. Cost to replace has more to do with the set up of your stringers, motor mount, etc. New Kubota is probably under $8K to purchase . . . with basic install maybe $12-15K -- installed with bells and whistles probably run you as much as $20-22K.

blowinstink,
Could you email the spreadsheet for the 5424. I am looking for some cooling system gaskets that I cannot find through the marine stores.

The heat exchanger has been replaced (don't know when, yet!)

Even tho I will have the boat surveyed, hopeful finding a surveyor with that engine knowledge, what are your thoughts on what to watch out for regarding this engine: Parts avail...cost to replace...transmission issues...you know, all those same question to a new boat owner.
any PROS or CONS
Thanks

That is not a lot of hours at all. The motor, if well maintained should be good for close to 10,000 hours. This is a sturdy little tractor motor. If really concerned have a mechanic look it over, or an engine oil analysis. Parts are quite available with some creativity with a few exceptions. Now if it has not been maintained well, then that it could be near the end. I would take one over a Volvo any day!

Re: Universal 5424 Diesel

The instrument panel isn't available, but one is from Catalina Direct for a Cat with the same engine. You'd just have to be a bit cunning with the wiring.

See here :

Catalina Direct: Electrical

You can replace the instruments with generic ones. I've replaced several, installed a quartz hour meter because the one in the rev counter broke, and replaced the ignition switch.

If your panel needed replacing though, I would use a CAD program to design a panel, have it made, and use generic instruments.

The electric pump is just a lift pump and any low pressure diesel pump should work. Catalina Direct have the correct one, though. For $237.
