Here are some more pics of exactly the order and orientation of the seals. I didn't reinstall them back on the crank but just put them over the end of the crank for illustration purposes. I also put them in the bottom crankcase half as well in the order they were actually installed. The bitch...

Here are pics of the pushed out outer seal and disassembly of the motor via photobucket - http://s893.photobucket.com/user/trx...?sort=3&page=1 Curiously though, the inner seal was perfectly in tact. Maybe pressure blew thru the inner portion of the inner seal and it stayed in place but it...

Ok, thanks!

Unfortunately I think that's what happened (on several occasions), I'm a newb to PWC and my inexperience has bit me hard this time! There was definitely water in the motor, twice! And, after the first time I had no idea (I rigged a hose off the pump line cuz I didn't have the proper adapter)...

Yes they were installed right, I took my time and made sure. I used yamabond 4 on the cases and also a thin coat on the outside of the seals. Dealership told me yamabond 4 is the same exact product as threebond 1211 just a different package. I already had yamabond. Whether I "hydrauliced" them...

I didn't know if WSM used oem seals in their kits or not. Actually I didn't even think it mattered. Are WSM seals bad??? I bought the full kit through the guy who did the machine work and figured they were good. They were installed right and meticulously. But for whatever reason they pushed out...

Ok, I have the motor ready to pull after several hours. But, what do you think caused this??? I don't want to do this again! They were seals from a WSM kit.

I just rebuilt this motor and have about 5 hours on it. It ran excellent till my last run at the lake a few days ago and it just died and wouldn't re-fire. I thought it was because I was almost out of fuel and I switched to reserve and had air in the fuel lines. Then after messing with it at...

Thanks!

Yes. And that reminds me, do I really need to run those things? They seem like a serious restriction? However, I do realize that the carbs are jetted from the factory with those in place, so... But for now I'm just looking for opinions on how the plugs look with everything stock.

Hi, I have a Yamaha 1100 (wave venture). I built the motor from the crank up. The only thing it has other than stock is boyesen reeds. I put about five hrs. on the motor now and it runs excellent. I'm running all stock jets and set low and hi needles to service manual spec plus a 1/4 turn out...

Yeah, well I turned the H/S & L/S needles out 1/4 turn and installed the intake sytem and ran it for about a half hour slow and fast and the plugs looked almost the same lol... so, I guess it's good. The boat runs really good and fast so I'm happy. Just didn't wan't to burn a piston first off...

My only concern is my plugs are burning a little light for my taste. However, I've been running the machine with no intake cover or flame arrestors, just open carbs so I could get to the needles for adjustment if I needed. Do you think this created a lean condition with needles at factory settings?

Hi, new to the forum and PWC (multi cylinder engines) although I've been a mechanic on bikes and quads for years. I have a newly rebuilt motor that was just broke-in and it seems to run great from bottom to top. Plug readings are identical tan to light brown. However I want to make sure my...
