B4 Out they come Col in action

[SteveE]

Phase 1 of getting B4 back in the water... Rebuild 2 engines:

 

[ACE]

Good Luck with your project !

 

[Sneds]

.....................and I was moaning about having to fix the bog!

Good luck, please keep us informed with some "work in progress" pics

Those two engines are approximately the same size as my boat.

I'd seen B4 out the water for over a year at PS, wondered what was going on.

What's the problem with the engines?

 

[SteveE]

The oil in the bilge is from the Starboard engine putting a rod through the engine casing.. The Port one dropped a valve we think...

 

[Morpheous]

That explains the grumpy looking looking person in the pic, is that you are the engineer who has to sort it out

How long before you hope to be back in the water?

 

[SteveE]

No thats Col on the tools, Barry on the Hiab and me on camera....

With a good wind end of July... Lots to do, and the list is getting bigger...

C'mon Col I bet Vicky did all the work as usual and you just posed for the camera

Glad I managed to fix my transom shields without getting the engines out though. Putting it back together will be quite a job I guess.

Bit tight being Mercruisers. But not so bad.
Crane was a bit of a squeeze. Lifts 3.9tons @40ft, so dipper arm is huge (as you can see)
We even had to take the hook off!

Why did they fail? It doesn't look like a very old boat to be having engines rebuilt?

The 250 d tronics are not the best motors, there on the limit, im sure latestarter will know all the pitfalls.

Nearly every one ive stripped has suffered crank failure due to oil overheat, especially in the BMW days, and cylinder head damage due to cracked valve seats causing the seat to fall out the head!

Appears that a rod bolt broke (not unheard of)
Can update once stripped.

In which case, why rebuild them? Isn't it just gonna happen again? Better just to dump them?

Exactly my thoughts, boat engines should be built to last many decades, like mine, now 44 years old and still going.

Would B series cummins fit?
