Will a crankshaft from a 61X case work in a 62T case?

What is the difference between these two heads? I have an ADA 701 head and was wondering if I could buy 760 domes for it and use it on a 760 cylinder?

I saw on Ross Champion's 2009 SJ that there were tubbies installed on top of the stock molded tubbies.....has anyone else done this???

If you have the Worx, Wamiltons, TBM, R&D or other specifically for a 2008 or newer SJ please let me know your experience using them. I have the short JD 08 plate and not really liking the ride.

Hey I wanted to throw this out there....what is your opinion on the UMI steering kit on a B1? I have some points that I will share after I see a few posts. If you have or used one, chime in.

Tried searching and only found a thread about the TBM plate and of course D cut stocker. I bought a new 08 JD plate but I'm not really liking the handling. Nose is down and sprays water up in my face like a mofo. I like to carve and used long plates on my 98 SJ - even in the surf I liked my...

I hate the UMI system. You can't get rid of the slop without really tightening the steering and the bearings are the worst design for salt water (duh). I bought teflon washers to eliminate the race bearing but the main bearing is still part of the system. Stock systems are better IMO except...

I need a new dampner but I have no idea what brand this is:

I've seen a few posts regarding why it's not a great upgrade from a 701 cylinder to a 760. Although it is larger displacement it might have weak bottom end? Some other topics of filling in the cross circuit...what's that? Is a 701 62t just larger exhaust bolt holes? Maximum bore for each...

Okay....I finished my 09 empty hull build. It runs sweet. Love the new hull! For my next project: I have an extra running Blaster with tons of aftermarket parts. I also aquired another 09 SJ hull. So, now I will strip the blaster to build the superjet. I will find out what parts are...

I been waiting for an answer from ADA directly....and am still waiting so I thought I'd ask x'ers here: Do they make ADA 86mm domes? If so can you put them on a 701 head or do you need to get a 760 head?

Has anyone run water injection on a b pipe? I have ski that has the headpipe taped with a water injector.

Just wanted to share some advise as two friends recently had issues with their skis. Had a friend who tore his SJ motor apart thinking the crank was seized...it ended up being his start/stop switch. Just had another friend email his engine was toast. I looked at it and it was his impeller...

If you have an 08-09 Superjet can you post a pic of where you place your registartion numbers? I see a few pics like YAMACAT's and that seems to work well with the limited space avail due to the factory decals.

Now that I finally have the title.... Took a new Yamaha certificate of origin for a 2009 Superjet to DMV and forgot that they are banned from CA. Supervisor was confused. Luckily, boats are not tightly regulated (like cars or dirt bikes) in CA. It didn't need a visual inspection. The lady...

For superjets, Yamaha usually keeps the gelcoat color for 4 yrs but changes the decals every 2 yrs. That said, anyone have peeps on what the new decals will look like for 2010?

What is the difference between the 2006-2007 waterbox and the newer 2008-2009 SJ waterbox. The part number is different.

Looking for the color codes for 1998-99, 2000-2002, 2003-2004 and the new 2008-2009. Seems the 98-99 is royal blue-ish but the 2000-2002 is purple-blue. If anyone has repainted with a custom blue color please let me know that code as well. thx
