Taking a 8mil and having it remachined for a stock stroke is like buying a Bugatti and paying a shop to swap some Honda motor into it because the oil changes cost to much. Can it be done, absolutely. Would you be better off selling a 8mil shortblock and buying a stroke stroke short block of your choice absolutely. Not laughing at anyone but hopefully you can see why I think that's a rediculous suggestion. The dude didn't buy a 8 mil to turn it into a shiny billet 701

Less bark down low, probably same power up top.

Ive got a couple hundred hrs on my stock stroke 850 over the last 2.5 years. Changed wrist pins a few times and pistons once.

Blow out all the water. Proper fogging(flame arrestors off, spray til engine is pretty much stalling while revving) take out plugs and spray some more for good measure. wet vacuum out the engine bay. Leave the hood off. Little care goes a long way.

Klotz ski craft 32:1. When i changed pistons i couldnt believe how clean they were. I didnt even have to at 100 hrs but i did anyway.

How do you "blow the water out?"

What product do you guys recommend for fogging oil?

@eastcoastjumper how much to do you weigh?

@dmpus how much do you weigh?

These additional questions are relevant to dmpus' overall inquiry:

What is the best size most reliable engine for a surf ski (likely a Rickter Edge) at say for example my body weight of 205 lbs...?

Should we be including the Kavinci 997 in these discussions yet?

Is 62T crankcase stronger more reliable than DASA crankcase or vice versa?

in Surf, A well ported 701 works well. The larger motor lets you get away with not having as much momentrum, you can turn into a wave and pin the throttle. Taylor Curtis has an awesome package with a 701 with OEM 155 pump in the Edges.

Water is blown out by cranking and revving engine out of the water. Fogging oil is used ie. Stabil. They are pretty close in size. No as it's not as readily available. Dasa cases are 62t cases that have been ported so no, they aren't as strong.

Think he may be talking about the Billet Cases.

Why does this matter to the OP?

How are billet crankcases relevant? Billet crankcases don't prevent bearing failures...

@DAG: I don't know. That is why I asked. The OP's original question is what is a similar powered engine which is more reliable? I am just peeling the onion a little further to ask essentially is there something more strong or reliable about the DASA billet crankcase than the Yamaha 62T crankcase. If you want me around (and I am not saying that you do, you'd better get used to my stupid questions -- because that is my highest and best use on any forum...) I just paid off the house yesterday. I would have preferred to just buy a $25K-30K prebuilt Edge. But my wife told me explicitly that she would divorce me. (I would have preferred to give up one nut...) Now I have to learn and save my pennies and proceed slowly. Oh, and love ya bro'...

about 3 peeps with similars set ups as dmpus in our riding group (eat coast freeriders) have blowned up their dasa's in the same way (crank going thru the side of the cases) and in a short time period . Is this a coincidence ?
Lower rod bearings failure seem to be the cause of the failure. I believe they were all ADR cranks...not sure. Maybe dmpus can confirm!

I had an ADR Crank that I caught the rear bearing right before it let go a year ago. Stock Stroke but failed just the same.

The crazy part is that I've used stock SBT cranks in my high HP applications and never had one go out due to lower bearing failure (except on a gp800 crank)
and they give a one year unconditional warranty!
