All single carb 750 came with 40mm throttle plates. If a larger carb is used make sure you also have a low pitched prop to go with it. You can install all of the parts including the jets from one of Gorgy30s (pacific jet sports) new 38s into the body of your stock 40 and basically have a new...

Any CDKII will fit your manifold and flame arrestor. The only other option is going to Mikuni and that will require changing the manifold and F/A as well. I know Gordy30 on ebay has some new CDK38s that will work without tuning. There may be some new and cheap CDK40s left over from polaris...

Find a 750sx nozzle.

Jetski and boats that we consume (except for some new AM hulls) are made in the Western hemisphere where everything is at least twice as expensive. Plus nobody can destroy good equipment like a jetski or dirtbike owner can. You have to either pay up for new or settle for SBT and used junk.

This is the problem with old skis. Their previous three owners had the same attitude.

The Kawasaki pump isnt as efficeint below about 15mph. Is your engine fourcycling from 1/4 to 1/2 throttle? If not the response will suffer.

Your 701 will bolt in and the 650 pipe will also work. You want to use the ignition box from the 701, it should be marked 61X or 62t. The wire in the head should pull out unless someone glued it in. Once the carb and pump have been tuned the power increase will be very noticeable.

Maybe someday hood tricks will be cool again.

Is the problem lack of power or lack of hookup? Cavitation will be felt as excessive vibration at low speeds with normal or high rpm. If the pump is smooth then look at the engine.

The price is different for every neighborhood. What would get you a pat on the back in one may get you prison time in another.

Reads like a trailer park tragedy.

I think the honda pump would be the poorest choice because its steep impeller angle. Most PWC drive train are six feet long and will take up a lot of floor space. A Mercury Sportjet is very compact by comparison. I would use a modern Yamaha or Kawasaki direct drive engine and put the pump in a...

I know one guy that killed a gang banger in Dallas. It cost him (his daddy) $14,000 to get no billed. He was also ostracized by everyone that knew him. Months after it was over he said, "All I had to do was drive away". Think about that before you let someone "make your day".

Silicone grease is ideal.

That is what happens when they are stored water in them. It would have been fine if the hood was propped up so it could dry out instead of creating a green house. This is why almost ALL old skis are junk.

There are plenty of BB/strokers out there that run no better than a good ported stock cylinder. There is a lot more to consider than size and looks.

The arm should be flat when installed. If it is sticking up it can hold the N/S open all the time. A 2.3 will a be a little rich with a 115g spring.

A spot of thread sealant will keep everything like new.

Very talented people have been in and out of the boat building business since the beginning. Making a boat and making a living building boats are two very different things.

They are both excellent but both will need some repitching for best results.
