Great Lakes Bass Fishing Forum

Hey guys,

I have a 96 ranger 391v with a 200hp merc efi.
I was recently fishing lake erie and snaped the crank shaft on my motor just below the flywheel.

I took apart some of the motor and can not find the cause of this all the pistons seem to be ok.

I just don't understand where the pressure would come from to snap the crank shaft.
I'm kind of just hoping the crank shaft is the only thing wrong haha like thats not enough right.

Anyway I don't really know where to go from here I figure I can spend over 2k and hopefully fix it or just by a new re-built motor for around 5k either way it sucks.
Or buy the crank shaft myself and make it a winter project.

Anyone who might have any input on what they would do or that may of any mechanics or places to find re-built motors would be greatly appreciated.
I live around the cleveland ohio area.

I wish buying a new boat was an option but its not I still owe around 5k on this one and part of me just want to sell it as is and hope to get around 3.5-4k and just eat it and then start saving for a new rig but I know if I either fix the motor or buy a re-built one I can probably sale it for 11-12k I think anyway.

Thanks Joe

I'd check out e-bay for a new engine. Hopefully you can find a great deal. I just bought a new trolling motor that retails at BPS for $789.00 for $490.00.

It is really odd that the crank would break with no piston/cylinder damage.  How do the cylinder walls look?  Motor turn over by hand freely?

You can rebuild it yourself if you are good at working on motors - not too hard.  I did a 150 XR6 a years ago - I had trashed the crank due to a bearing failure.  Block was ok.  Honed it and re-ringed and it was good to go.  I had about 1700 in the rebuild.

If you do elect to go with another motor - I would really want one with a warranty.  Buying a used motor with no warranty is like buying a time bomb.

Good luck!

With new boats pushing 50k repowering older boats is starting to be a viable option...If your boat is in good shape and you really like it a new motor may be money well spent..I have seen brand new in the crate 200s for around 10 grand....That gives you the warranty you may be looking for and you will have a boat with a brand new motor..
If you don't like the hull then you have kind of a dillema..Hulls without motors seem to be very hard to sell...
