Switched from dual 44's to a single 48 on my 62t 760, going to drop the motor in tomorrow during the day and see if it starts. :)

Had this motor built and put less then 10 hours on it. Back em if you want, say you never had a problem but it is what it is. I have probably hyrdrolocked or seen someone hydrolock a motor 50-100 times in the last 3 years. 1-50 actually bends a rod, I will give that much but crack a journal...

We have tried sealants, new seals, cleaning old seals, new screws and it never ceases that multiple people in the group have water in the box (though the 08 was a bad installion by the Factory monkeys from yamaha) I have wondered many times about a plug on the top and a plug on the bottom so...

Whats the biggest bildge pump someone has successfully used in a standup? I finished my build the other day and used a 1100 gph attwood. The only complaint was I had to get an adapter and a little silicone to make sure it did its job and didnt come off. It can also double as a fire hose if my...

I am just wondering which would make better power a dual carb pjs 550 (ports are pretty insane, its a reed port spacing that bolts onto a pp crank) or a stock 650 with upgraded carb... Seems like a dual carb fully ported 550 would eat a 650s lunch along with less fuel and cheaper parts...

Thumbing through ebay saw this with a temp gauge. Being that seadoo, yamaha, kawi, have never thought to put a temp sensor one would think there is no logical reason to put one on there, then again most the time they dont change anything on a jetski for years on end... Is this a good idea or...

I did a quick search and didnt see what I really am looking for... My questions is with the cats trim I got it looks like it puts my brand new cable in a bind and it wont last long, is there a different screw on part that I can put on the end of my steering cable instead of the screw on piece...

YouTube - The study of Waveology - for the back -flip First day was pretty good. We have some more footage of steveowe when he gets done editing he will post up as well. We are using a waterproof camera from the middle of everything so timing is a little tough but there it is, my first backy...

Can you run a 550 coffman waterbox on a superjet and would it be better then the stocker if so? the fittings look like I could make it work.

One of the board members is doing all the machine work and porting work. Will let him chim in when ready if he wants to, I am am sure my words will not do his work justice and from the looks of it, its amazing and I can't wait to run it. The platform is a 61x non ported cylinder and 64 Y...

Fired it up to head to ocean, no problem get there and all it does is click:crutches: pull plug and see something, SteveOwe let me ride is ski in the ocean though so it was a great trip after all. I thought the motor was rock solid, been running like a champ all summer long and now it decides to...

To start I am having a big motor built after being frugal all summer and gathering parts as they came up reasonably cheap and finally nearing the end. My question is do motors really loose that much value. I did a quick search in the parts section and found numerious stroker motors that were...

I picked up a protec girlded head the other day that has 4 inlet/outlets. Most I have seen have 2, what should I do with the other 2? I am runnning this on a 84.5 sleeved bb on a 760 case with a b pipe. Compression is going to be about 190~. I am planning on tapping the exhaust manifold for...

Our local group of guys met on the river and had about the best time of any ride all summer. The river is usually really calm Except the occasional boat. Today we met some boaters and steveowe talked it up and they filled their balast and let us play on there waves for 1-2 hours. They were...

Ebay item, I cant believe they are only at 10$ granted shipping is 50 but still 60$ for 62t cases is awesome right? I am high bidder but dont really need these thing... what does it cost to get a crank rebuilt to stroker specs, just something to up the displacment. It doesnt say in the title...

I know what it is and what it does but dunno why replace the stock one? is it mostly for making two singles into dual carbs on the cheap or is there a purpose? I did some searching and found some mention of backlash but saw no definitive post on this subjet. I am rebuilding and rejetting...

I changed directions sold the top end (it was shipped out today) since its winter and carb parts took so long I am sending my stuff off to be worked over, I found a cheap 61x cylinder local, BB sleeves that look like the NW sleeve ones and have the pistons sitting on the shelf, and carb parts...

I was looking on ebay trying to find some carb rebuild kits and came across this, I looked up part number and only found it corralted to a kit... if there really is 6 rebuild kits 50$ is a killer deal I think for mikuni kits right plus all the other stuff included...

I was searching online and found somebig bore sleeves for 75 a sleeve brand new with instructions so I called the guy up to see what the deal was. They have different sleeves apparently freestyle, superstock and modified I think (wasnt paying attention to the last two after I heard freestyle but...
