Yes they have been out for a while its a RCMK twin they had a recent recall for the cranks but those look like the new ones being water cooled and everything.

yeah, new ones

martno1fan

Id make sure they are the new ones as Gizmo is still out of stock so id think if they were available Bruce would have them in stock by now ?.

Seems your right these are the new ones,maybe Bruce is waititng till he gives replacements out before putting any on his site.I like how RCMK do buisness,fixing problems and making sure its customers get replacements if need be.Good to see they have fixed the crank problems,think this will be my next engine not long till christmas now .

Having modified a couple of the 520 twins at this point, can pretty much say original picture posted on first post is the original engine that is having the crank issues.
The mating of the two cranks was done via half shaft mating with an overlap, sadly they failed rather quickly sending RCMK back to the engineering dept. Word is for them to mate two cranks and absorb the pounding of two independent engines the cases are being redone as well. I know at this point the two engines I had done are yet to receive updated parts from RCMK, tho have no doubt RCMK will make good on there goof up

Scott someone i know over here bought one of the first ones and had it sat on the shelf,only a few weeks ago he got a package from them with new cranks and cases i believe.He didnt even know of the issues as far as i know ,not bad customer service lol.

Here are the pictures of the new S520.

WOW Impressive machine work.
With degree of complexity now in the design, really curious whats going to happen with the price

** Curious, is there a picture showing if the outboard case half's of PTO and MAG sides are still running 2 bearings side by side ?

Price: $552.00
But as it was posted earlier Bruce is taking care of customers who purchased the first version before the reworked model goes on sale to the too the rest of us.

Hi Guys
well this how it goes with the S520 Evo, Ive had mine since they first came on the market (its still unrun in the box) due to the crankshaft problem !

I recived an email from Mr Park yesterday Sat 25th to say that he will be posting off a complete new bottom end to me on Monday.

so those of you that have this motor have nothing to worry about.

Bob.

qdemon

Watch this Space Sam you will be seeing mine shortly

Bob.

(qdemon on Jim's).

Hi Bob,a mate over here who has one of my hulls also has this motor and was sent a new bottom end,he hadnt tried the motor and was sent the parts without even knowing about any problems lol.That to me is great customer service .
