Re: Fitting atomic 4 into Catalina 30 (that was made for universal diesel)

Providing parts are still available, probably the easiest and least expensive solution is rebuilding or partially rebuilding the 5411. The good thing is that the liners are bore-able to .020 oversize or can be replaced.

A service manual is found here:

http://www.westerbeke.com/onlinemanu...hnical_man.pdf

To get the engine unsiezed, take off the head (loosen the bolts incrementally in the reverse order shown on page 12 of the above manual.)

Take off the oil pan.

Take off the connecting rod cap bolts and caps. Do not mix them up. keep them with their respective rod. Take a long, preferably hardwood dowel, and insert it as best you can into the underside of the piston and drive the piston out through the top of the block with a medium heavy steel hammer. Do the same with the other piston.

You'll probably find that this frees up the engine, the bottom end of these engines is exceptionally robust. If there was no water in the crankcase and the crank spins freely, it's probably ok. The condition of the rod bearings can tell you a lot.

I did a poor mans' rebuild (rod brgs. rings, honed the cylinders, unstuck and cleaned the injection pump, replaced governor bearings) on a severely flooded M20 about 12 years ago, at the time I lost track of it about 4 years ago it was still running strong.

Your intended use of the boat could reflect the amount of expense you invest in the engine.....

Beware of driving the pistons out the top, if the cylinder has a ridge, as many well worn engines do, you will break a piston ring land.... and if there is any possibility you will reuse bearings, make notes of how they are oriented and where they came from...

Re: Fitting atomic 4 into Catalina 30 (that was made for universal diesel)

The Beta 14 is an excellent replacement for the 5411 for less than $9,000.

The 5411 is based on a Kubota engine, cross reference the model # on the Kubota site and buy your internal engine parts for about one half Westerbeke/Universal's price. Example glow plugs for a Westerbeke genset,$59
Kubota engine parts $29 - SAME plugs.

I am also parting out a 5411, send me a PM and tell me what you need.

Atomic Four parts: I am selling my entire collection of A4 engines, parts, etc.
Check on E Bay, 2dogsfishin or search Atomic Fours.

Ya the head is off and as of now possibly missing (an old man was helping me and has the head system and appears to be stiffing me. So aside from dealing with that I may only have the engine block and the gear box). I took off the oil pan
and it looks ok inside I think. A little rusty up in the piston chamber. The build up on the top of the piston doesn't look bad.

Re: Fitting atomic 4 into Catalina 30 (that was made for universal diesel)

She's your boat, so do as you see fit, but...

A4 will be a big liability for resale (no judgment intended, just fact)
You will spend more time and money to get it to fit and work than you planned
The re-engineered install may have some unforeseen shortcomings

IMHO- Same time and dollars would be better invested in rebuilding/replacing the diesel

YMMV

Re: Fitting atomic 4 into Catalina 30 (that was made for universal diesel)

I just picked a 5411 up on craigslist, mostly for educational value. Had water in cylinders, seized of course. Injectors and lines are AWOL. Crankcase had black oil in it (good sign) so I assume the bottom end is good. I will try to free up cylinders. Depending on how far I get, I may have parts available. Head needs to be redone.

Re: Fitting atomic 4 into Catalina 30 (that was made for universal diesel)

I removed the 5411 and installed a fresh water Yanmar 2QM15. It was a pretty simple swap and only had to make one new engine cover for the frontside. It sticks a little farther forward than the 5411. The engine and parts all cost $1,000 total.

Re: Fitting atomic 4 into Catalina 30 (that was made for universal diesel)

Looks like i was able to get ahold of a rebuilt engine block for the 5411 along with most parts. i'm having the cylinder head looked at to make sure it's usable. My timing cover/gear case cover is cracked around the water pump mount (like someone dropped the engine on it.....). Does anyone know where i can find a used one to replace it. There's on on ebay for $400 so i'm trying to get a better deal than that....

I have parts available. Everything except except tranny, fuel filter, injectors and lines. Make me an offer on the gear cover.
