My set up and why I installed one. http://greenhulk.net/forums/showthre...o+785+strainer

Pro 1200 is similar, but totally different.....

Both Pros do around 63 MPH from the factory. They both use the same hull design and are very aggressive. They both achieve similar HP, but go about it completely different.

Pro 785 uses a high strung 785cc engine turning almost 8k RPM with trick parts such as 44mm carbs, exhaust valves, and factory installed triple pipes.

Pro 1200 uses brute force with a 1200cc engine turning almost 7k RPM with a single pipe. Much more simple design, and were domestically made engines. (785 were Japanese Fuji design)


I want to say for some reason, i think the Pro 1200 has problems with the drive shaft? Someone else might be able to touch on that subject as I never had a Pro 1200.

There's a member named Derwood on here who owns both Pros, and might be able to give you a nice comparison of the two.

Here's the sales brochures for both skis.

There's a ton of info in the "tech" section if you ever have some free time and want to do some reading up.

I found a second Pro, working in getting her home. It’s a 2000 Pro 1200. Were they a bit slower due to its weight? Much difference between a 99 pro 785 and a 2000 pro 1200?

I can't speak for the 1200, but I believe it's more or less a standard domestic 1200. Meaning smooth power curve, runs more like a standard engine on a regular boat.

Pro 785 depends heavily on the pipes. They hit around 4500rpm and when they do the ski goes from being slow to wanting to rip your arms off. I like Pro 785s so much because they have such a ridiculous power curve.

I remember first time I got on it, I went from an SL 750. I gave it a little gas to 4000rpm and it felt slower than the 750. I thought I really screwed up. And then the pipes hit and I was addicted.

1200 should be more like a 4 stroke, more linear power curve without a big jump. I don't know if Polaris did anything special to the 1200 engine or not. I assume they did something, at least.

785 was a special motor. It is basically a standard Fuji 750 with a stroke for more displacement and all the racing stuff thrown on, bringing it from 80hp to 135hp. The paint is wearing off on one of my pro 785 engines and underneath it's Fuji blue paint, lol.

1200 is not special. They could have done some slight tuning, but it's the same engine found in the Virage TX and other 1200 Polaris PWC.

I know someone else can chime in a lot better than me, but when I was choosing between 785 and 1200, my researched showed 1200 didn't hit as hard and wasn't as fast.

Pro 785 0 to 30 is still pretty close to an Ultra 260x. Ultra is little faster, Pro 785 is a little over 2 seconds 0 to 30 and Ultra 260x is a little under 2 seconds. But you can still throw a pro 785 around, jump, etc. Ultra 260 weights over 1000lbs while Pro 785 is 480lbs.

But I'm getting off topic. I think Pro 785 is better than the Pro 1200, but I never rode a Pro 1200 so I'm just pretending to be an internet expert.

Great info. Damn I’m liking the 785 more and more. Wish I could get on the water. Might need to take a trip south! As far as the East Coast Watercross. Can anyone enter? I’d love to get into it but have zero experience. What are the classes? I’m in NYS so I could easily hit the Watkins Glen one.

I have a throttle cable question. On the 785 the threaded end was stripped to a point where I couldn’t tighten the cable up enough to get all the slack out of it so I went to eBay and ordered a used one on eBay. It came in with a section of threads missing but less than what I had. It looks to be worn down and doesn’t look like a factory machining. The company I bought it from said he went to his shelf and said they all looked like that. And said it comes like that but I can send it back if I wanted to. Here is a picture of it. It this normal. To me it looks like it was worn down from being loose in the bracket.
Also is this MFD stock from the 99 Pro 785? It looks like it was not installed from the factory like this. Has anyone used gps speedo’s on any skis?

I saw a post on somewhere here that there was a carbon fiber plate behind the MFD. Did someone make them? Anyone still have a carbon fiber panel that the MFD sits in? Mine is pretty beat

mcmaster carr is your friend. If you want cool stuff on a Pro 785 you have to make it yourself now a days. I need new beach house sponson mounts and I can't find them, so I'm just going to make them.

You already have a template with the old version, all the hard work is done. You just need to cut.
