Wish they had gone for less weight. at 375 it’s no lite weight. But much better than the 560 of the pregnant Kawi. Lol

2 smoke or 4 stroke?
Last of the 2 strokes I heard from @cyclone
In the picture the "TR-1" engine sure looks like a DOHC 4 stroke.

Thing sure has an ugly front end.But they did a better job than kawi did with the size and engine package the tr1 is a great 3 cylinder engine and being 200 pounds lighter overall than the 1500.

Saw that it is just 69lbs (nice) heavier than the previous 2 stroke model.

Yep.... this one is gonna cost me. I have a 2018 that I'm building the motor on right now. Love the two strokes but these will be sweet once we can bolt up a turbo to it.

The two stroke was 73 hp for 291 pounds or 3.99 pounds per horsepower.

This four stroke is 100 hp for 375 pounds or 3.75 pounds per horsepower.

Looks nice.

56mph? Gotta be a mistake. I was doing 70 on a stand up in 1994.

It also needed a new top end once a month

I like the wide tray. Always felt cramped on a 440/550.

This thing has my attention. Had no idea the Kawi was so heavy.

Also like the lack of gaudy graphics

Being a 4 stroke..are they EPA legal to ride everywhere?
As far as I know, yes. Well, anywhere that allows jetskis. Up here in Washington, we have an area in Puget Sound (San Juan Islands) where any jetski is banned.

If you still had it and was clean it pull about 3500 today.

Had it for 4 years, was in clean condition with a few upgrades and sold it for $4500. Buyer was taking it to Brazil to race it.

I belive you. My 750sxi was pretty fast but nowhere near yours. I need to convert some of those mini DV tapes to youtube. Nothing like crashing so fast the lid comes flying off

Sold my 90 super jet two years ago for 1k. After 28 years I had gotten enough use out of it. Glad to see them step up with a 4 stroke. I would love to demo or rent one of these just for old time sake

Is this Jacobs, The Fish Or McCluggage? Holy Chit-I had a Jacobs PJS Race Gas 440 Practice Motor in my old 550 W/ a 440 Pump. Blew that up in 1 hour. That SX 750 Smoker is no Joke. Almost as fast as my FX-1 was back in the day;)....All my flat-nose SJ friends sent their stuff out to Group K under the Radar, we'd be at Temple Bar, ready for our 6AM launch to camp-and I'd fly right past um on my FX. Gawd I miss that ski.Long Live the 2-stroke.

nope, but i did practice at senators with Jacobs, Fish and myself had the 1st 2 HX's. His arrived a few weeks before mine. mac helped with a broken leg at race in 84 I think it was.
I watched the races last week on ABC, from Florida and Georgia. Its a shame how bad its become. Farthing son did well, so did Rustys son.

That's badass, @SJP you're Drypipe Kawi was a runner and the price was right.

Yeah - that was a cool ski for the $. Loud as F but I think that was half the apeal for me at the time. I broke down and reserved a new super jet. I want a new 4 stroke for long runs but the 1500 is just too much literal boat. When physically it does not fit the stands, trailers, etc I am over it.

@Lavey5150 here are a few old pics of the skis

Jacobs mod 1992 550 with the efi hit a top speed of 57mph on the courses i think the next fastest ski was about 52-53 and some were 750s.PJS had game up on everyone too bad bad business practice put them under and out.

Some of the current vintage class 550s are pulling some impressive numbers too right now but not near 57 mph.Quite a few older westcoat 520 and pjs cylinders are in use today with older skis and instead of an outdated 440 pump they are now using the 750 pumps.
