1995 Searay Sea Rayder Sportjet revival

This jet boat was quite the basket case when I got it. It had no spark, then erratic timing, then ran backwards and a whole lot more.
Lets see if we can get this 95 120XR sport jet powered Sea Ray back on the water!
Here are some of the special parts and tools I used to get this thing running and lake worthy again:
➡ CDI Electronics 174-9710K1 Stator: amzn.to/47IHD8z
➡ Innova 5568 Timing light: amzn.to/48HP9ll
➡ CDI Electronics 511-9766 Spark tester: amzn.to/3u2Oo7r
➡ CDI Electronics 144-1889-51 Rev limiter box: amzn.to/3UccnvB
➡ Ride plate Screws 10-824830 : ebay.us/9XGgcE
➡ Ride plate Seal 830123-1 : ebay.us/2UTyMt
0:00 Intro

3:52 New stator

Thanks for publishing this video it has definitely helped me work on my jetboat which is pretty much the same as yours (96 bayliner jazz powered by the same motor as yours) My motor is freshly rebuilt and bored .030 over but hasn’t even been ran yet because I couldn’t figure out what was preventing it from running since it got rebuilt. I was just getting ready to start taking the motor back apart but thanks to watching your video I figured out that my rev limiter is bad. I couldn’t even get it to sputter until I unplugged my rev limiter. Believe it or not it was turnkey prior to the rebuild even with chewed up cylinders and pistons and next to nothing for compression which I discovered after I already bought it and tried to actually run it on the water. Rookie mistake obviously on my part not to do a compression test and water test prior to buying it but I was fooled by how easily it fired up and seemed to run good. So now it spits and sputters with lots of smoke but still doesn’t quite fire up but now that you included setting the timing in your video I’m going to check and adjust mine and hopefully that will bring life to this motor. I actually have my motor on a stand right now and was thinking about rebuilding my carbs while I’m at it. I went looking for your video of rebuilding the carbs but couldn’t find it. Am I just missing it or is that not on here yet?

[@trythistv]

I haven't gotten that video done yet, I should try to finish it up soon, they are very simple carbs.

[@prestonbonesteel166]

That would be great! I’ll keep an eye out.

[@tiffanyevans3899]

Beautiful footage at the end there! Looks fun.

[@trythistv]

I've kinda got the best drone pilot ever.

[@styleauto1025]

Very good video thanks for doing this

[@trythistv]

It was a lot of fun to get this thing back ship-shape again!

[@ameliahoffman5960]

Hey there, I recently purchased a ‘93 Sea Ray Rayder Sport Jet from Wisconsin Dells that ran last summer but needs its carbs cleaned and won’t start for us. This restoration video was absolutely inspiring! However, I have NONE of your know-how😔… Is there any way you could point me in the right direction, or tips where to take it?? I would pay handsomely to get this beauty back to her former glory! 14:20. Love what you’re doing!

[@trythistv]

Hello! The first thing I would check is the ignition system. You can either pull the plugs and use a tool like I did in the video: amzn.to/3yde7fh Or you can just try to start it, using a little starting fluid or some gas dribbled into the carbs. Once you've verified if there is spark, pulling the carbs off is fairly simple, and I have some video footage of rebuilding the carbs on my boat, I just haven't taken the time to figure out whats missing and put it all together or re-shoot any missing information, but I will work on that soon and get a video out about rebuilding those so you can watch and rebuild your carbs. They are fairly simple on these.

90’s cup glory boat

[@trythistv]

I swear the boat is floating in water, that is not vodka...

[@styleauto1025]

I had the very same issue with a 90hp i can send you the video i had the same issues with the gasket i didn't replace it i just put it back on it doesn't go very fast do you this it the gasket i need to replace?

[@trythistv]

Is the video on youtube somewhere? I'd be happy to see if I can notice anything from it. If its revving up but not going fast, that seal is a likely culprit, there are some other things it could be, but I'd start with making sure that is sealed up real well

[@BrandonRodriquezmx73]

Do you have the part numbers for the ride plate gasket and the screws. Mine has the same issue.

[@trythistv]

I sure do! Screws 10-824830 : ebay.us/9XGgcE Seal 830123-1 : ebay.us/2UTyMt Those were the part numbers I ordered that worked great for me. If you look at those links, some of the listings on ebay have more than one screw so you can get a deal like I did and have some spares.

[@mikehaddad5429]

Just got one of these. What battery do you have in yours?

[@trythistv]

I've got a group 24 marine starting battery, I believe mine is an interstate but any good brand (not everstart from walmart) will work great!

[@JoseHernandez-di7lm]

Hi do you know how oil I need add to make 5 gallons of gasoline

[@trythistv]

If you're wanting 50:1 ratio that is typical for jetskis, outboards and jet boats like this you will want to add 12.8 ounces of 2 stroke oil to 5 gallons of gas! Hope this helps!

[@LEFTHOOQ]

Mate I have the same one. Engine was rebuilt runs great but won’t go more than 10-11mph. Any idea where I can start looking. Many say wear ring. Thank you

[@trythistv]

Does it rev up and not go, or does it feel like the engine is just lugging and not making power? I had cavitation (feels like a slipping clutch, engine revs but doesn't make the boat go faster) and it turned out to be the ride plate was letting air into the pump. The wear rings on these are stainless steel unlike the plastic rings used by Seadoo, so it is possible, but I would look up in the pump from underneath or from the back and see if you can see a big gap around the impeller before you start digging into replace the wear ring. I'd be looking for air intrusion if you're getting cavitation.

[@LEFTHOOQ]

@@trythistv it revs and goes, it just doesn’t reach a faster speed than 10-14 mph. It sounds like it’s working fine. Could it be a wear ring ?

[@trythistv]

@@LEFTHOOQ If its revving up and sounds like its running fine then it is something related to the pump. The wear ring is a possibility but rare on these due to being a stainless steel wear ring. I'd inspect the wear ring with a flashlight and see how it looks.

[@user-pwfus]

How much would you sell something like this for?

[@trythistv]

I've seen them non-running for around 1500, and in running condition for around 4k, really nice for around 6k, I'm hoping somewhere inbetween those, mine is running really good, carbs freshly rebuilt, everything gone through mechanically (pump oil changed and all that), and I've got a basically new bimini top for it, new stereo, speakers and all that so I'm hoping for 5k or so

[@JohnKyle-m3r]

Is the engine not starting the only thing a bad rev limiter will do? If unplugged, will it run normally?

[@trythistv]

If I recall correctly, it would make the spark intermittent sometimes, would randomly be fine, other times no spark, when unplugged it would run normally but if anything went wrong and the throttle stuck or something then it would likely go kaboom in a very bad way
