first run in my boat, typical questions probably boring for the experienced

[cli55er]

took out the boat for the first time. must say these things are very simple to launch.

gave it fuel throttle first time and it reeeeevvvvveeddddddd then about 5-8 seconds later i was on plane. took it a bit. got up to what the speedo thougth was 50. ran really well. didn't die or sputter.

the port side motor runs about 500 rpm higher at full blast compared to starboard motor. port: 6500 starboard 6000 full throttle.

seems like the port motor moves the boat better when running one engine at a time too.

i wonder if i have a decent wear ring on the port side and a bad one on the starboard side.

the dang oil jug leaks oil out of the low sensor hole. that seal doesn't hold the oil worth a crap.

it may just need to have the cable adjusted on the starboard side to get more RPM to match the port side. not sure.

other than that it ran fine.

reverse....pretty much takes all she has on the throttle...is that normal?

thanks.

Hank :cheers:

These boats live and die by a multitude of adjustments.They are a hobby to own one.Good luck you will be able to get her right by forums and a good manual.Those old speedsters haul azz.On a jet 100 or so rpm`s mean alot at top speed.it should do 55mph and get there really fast.

 

[Dr Honda]

OK... the only question I see is about reverse. Jet boats just don't do backward well. If it backs up at all... then it's working.


As far as the RPM differnce... I would pop the air boxes open, and make sure the throttles are sync'ed engine to engine. Also make sure they are opening the entire way. BUT, if you make an adjustment to the cables... MAKE SURE THAT THE CARBS AREN'T HITTING THE STOPS ! A big mistake people make is that they adjust the cable until the carb hits the stop on the open side. When that happens... eventually, you will break the cable from mashing the throttle lever to full. So, push the throttle handle till it stops, and adjust the cable until that cabs just miss the stop.


While you are in the engine compartment, check the compression on the starboard engine. The other reason it could be running lower RPM's, and that it's not pulling as hard as the Port engine is that it could be getting tired.

Let us know what you find.

 

[cli55er]

thanks Dr. Honda. i am grateful for the information.

i checked the compression before we went out and it was 135 on all 4 cylinders. so assuming 150 is perfect, i think it isn't too bad yet.

i think the cables are just jacked up cause someone in the past was not kind to the thorttle linkage and levers. i adjusted them for stiffness on the levers and they are loose again, so yeah....pretty rigged up. i will take the tops off the carbs and follow your advice along with the 95 shop manual (i found it online)

it does back up....its just slow...so i will go with that and be happy. ;0)

i am going back out with my dad tomorrow. much more motoring experience than me, so we hope to find out more then.

today was a lets see if it leaks/floats/runs and how fast etc etc.....plus i have never launched a boat before....nor retrieved (obviously) it was very easy.

i'll touch base tomorrow. thanks again friend!

Hank

 

[cheappc]

It was easy? wow lucky for you!

My first time out launching, I took my girlfriend, my boat wouldnt start, when it finally did start, it died again and I hit trees, the dock, another boater, it was horrid!

Also coming back in after I finally got it going was scary too.. I had to jump out in the cold water, I was afraid to keep running the motor all the way to the shore.. I was afraid i was going to eat a rock in the impellers...

So I beat it up alot, Im really glad it was a used boat I bought, my friend bought a brand new seadoo challenger and she paid $25k for it and the same thing happened to her, it hurt me everytime I hit against something, so when it happened to her it really hurts, $25,000!!!

Now Im glad I bought a used boat, because Im learning so much...

 

[cli55er]

yeah that is why i bought used too, i didn't want a 12 year note or to pay for that long or that much.

i paid 2k and i'll learn all i can and use the crap outa it.

i learned today that telling your father passenger if he is holding on before doing a left 180 is not that same as hold on really tight cause i am going to have some fun. long story short he flew out....it sucked. we lost both our glasses and had to make it back blind as bats. and then we docked and loaded that way. my pride is hurt and he has a knot on his head. so what a great day.......live......and ......learn. good thing is.....we have life jackets. cause if he had passed out that would have sucked. he flew right in front of me, hit me and went in the water. i yanked the safety switch just in time. i will never never do that again....and to tell you the truth seeing your father fly out like that and go under the boat......makes you want to sell things....

no grief please i just want people to learn from mistake today. the youtube videos of people doing that crazy stuff in these things is not always going to work out the best. i know what happened could have been worse, but i am glad it wasn't and i wont do that again.

well, Dr. Honda....here is what i learned today......if i give the starboard motor full throttle on its own....it get barely anything it just REVSSSSSSSSSSSSSSSSS to max and goes goes goes, but we really don't go more than about 10 mph if that.

give the port side motor gas and it reves to about 4k, holds there and starts to pick up, but we never plan out.

give them both full gas......starboard motor revs high and finally with the help of the port motor we get on plane. about 10 or more seconds later.

the first time i gave it full throttle....it got on plane in about 2 seconds. it was fast....then it never would do that again after that.

there is diffenetly something wrong with the starboard motors out drive or impeller or wear ring or something.

thoughts?

thanks,

Hank

Hope your Dads alright,that speedster is way over powered.Replacing the wear ring is simple,$35.00 and a couple of hours work. Mine doesn`t have the power[single 110 hp],but after sealing the shoe,new wear ring and a solas xo impellar change ,I`ve been having a great time on cedar creek[east of Dallas].That was,Until I sucked up a rock near the ramp[thought it was a stick]had to remove gate got stuck in stator.Now my speed is reduced and cavitation is back.This winter I`ll have to remove impellar and have repaired.Again be careful

 

[Dr Honda]

The motor that is reving out is cavitating. With as bad as you are saying it is... you have an air leak. Most likely, it's coming in around your drive shaft seal. It could also be a bad wear ring, or impeller. Just plan on doing a clean-up on both pumps, and driveshaft seals.


135 psi is getting tired. If you are going to keep the boat... plan on a new top for each of the engines. Do it sooner than later. Right now, you may be able to just put in new pistons and rings. If you wait until they shatter... then it's a full rebuild.


Either engine should be able to get it to plane out on it's own.


The engine that is hooking up, and not reving... if you were closer to 150 psi... it would come up to 5500 RPM's, and accelerate. (eventually coming up to 6200 rpm's since you have 657x engines)

If you get the performance issues worked out... you will have a good time with the boat.

 

[cli55er]

here is my plan this winter.

1. rebuild carbs.
2. rebuild top end
3. rebuild driveline parts
4. rebuild pumps.
5. new impellers and wear rings


maybe by next summer i will be in good shape then. ;0) anything else i should do as a normal PM item on these boats?

thanks,

Hank

 

[Dr Honda]

If you do all that... your boat will run like new.

Just an FYI... you may not need new impellers. Just check them out once you get the pumps off.

FYI 2... Skat-Trk swirl are the best for "Out of the hole" or towing a skier, and Solas Concord or best for top speed and fuel economy.

 

[cli55er]

bring back this thread. i have pulled both pumps from the rear of the boat. had so much silicone on there i had to pry them off after taking the nuts off. one of the impellers was badly damaged, the other looks brand new. i noticed when spinning the blades they would grab then let go of the wear ring and the wear ring would spin with the blade when it grabbed. not good. i was able to remove the wear rings by hand with the impellers in place.....again not good. the housing was toast i would say.

so i ordered all new pumps from onlyseadoo.com (seadoosource.com). also ordered new driveline seals on both sides. they come put together already with everything installed except the impellers. i am sending off my impellers to Impros for inspection/repair as well. i have been working with Nick and so for he has been a great asset to have. he shipped me the impeller tool while still working on the rest of my order so i can save time and send my impellers off for repair.

no wonder i was having crap launches and bad cavitations. the pumps were put together by a moron/idiot. one of the pumps also had water in the oil....blugh....not good again.

driveshafts look to be fine.

i have taken all of the interior out now.....just want to say....DAMN YOU CANADIANS for putting those bolts where you did. i didn't think i could bend in those positions and my body says i can't this morning now.

i have contacted Keith Haas about the interior as his price is really good considering what all i would have to go through to make my own including buying the material. i'd gladly pay his price and just have it ready to go.

i also order a bimini top. 1" double walled with support poles, 3 bow 46" high for 129 shipped. haven't recieved it yet so i can't comment just yet on the quality.

no motor work this year, it should beable to run another season or two i would think. i also figured out my wiring issue and the thing now beeps at me when it is in the wrong settings to start, etc.....also replaced the temp sensor that was bad on that one motor that was sounding off the alarm constantly....probably prompted the last owner to disconnect it i'm sure....lazy ass.

i have 6 weeks to put this all back together.....thats the camping trip, wish me luck

more to come.

Hank

 

[Dr Honda]

Sounds like you have a full plate.

Not to make you upset... but your pumps were probably OK. The factory rings fit well... and if you have aftermarket rings in it now... sometimes they don't fit very well.

Keith is a great guy, and will take care of your needs. I'm glad he's a member here.

Post up with your progress. :cheers:

 

[cli55er]

yeah they were aftermarket "white" rings. i could spin them by hand and they pulled right out. i put them back in by hand too....no need to press or hammer them in. just went right in. looked like they tried to silicone them in......you could see where it scuffed up the pump housing really badly on the mating points between the new ring and the pump housing. looked like the metal was wiped in one direction....like the ring was spinning inside the pump housing along with the impeller almost....i'd say at this point even factory ones would be alittle looser than when it was all new and i really don't want to buy all new seals and bearings for a possible bad pump.

i'm not upset about buying new pumps....they will have all new bearings and seals and shafts and wear ring all done for me and they will look good as new.

the driveline seals were toast for sure.

i'm just hoping after all this i still don't have cavitation.....like as in the ride shoe is leaking air too.....blugh...that would suck. it looks like the ride shoe may have been taken off at one point....as there is silicone smeared everywhere.

i think based on the way the boat was acting when i got it, i had bad impeller one side and was sucking air in through the driveshaft seals. fingers crossed that is what it is.

thanks for checking Doc!

Hank

 

[parrothd]

You need to put a small/short screw from the outside of the pump into the wear ring to stop the spinning..

 

[cli55er]

got the pumps rebuilt and put together. just need to seal the seams all around on the ride shoe just to be sure and then reinstall the pumps.

i also have new driveline seals ready to go in.

i have 2 weeks before the state park trip, so i hope to have a trail run next weekend.

will keep updating.

Hank

 

[cli55er]

got the pumps put on, fixed all my little bad spots on the boat with epoxy putty, redid the seats and put them in, installed the stereo, put new lines on the pee lines and the exhaust lines (lowes vinyl line...worked awesome). took the boat out yesterday to test.......FREAKING AWESOME!!!! got on plane in about 3 seconds and topped out at about 50 and hit a max of 55 on a good run. attribute that to weak motors. the right motor was running 500 rpm more up to about 3/4 throttle, then at full throttle it was running about 500 less than the left. i get 6500 on the left and 6000-6200 on the right at max throttle. i'll get that all worked out when i rebuild the top end next year. for now i'm just going to enjoy the crap outa it. i even got air jumping my own wake yesterday cause i could literally turn so fast and then get onto plane before the wake went away. it was insane! thanks for all the help everyone! oh...i also kept it on plane down to 20 mph...i didn't try less.

also tried moving on one motor at a time.....no problems there either. and also this was with a full tank of gas.

motors are too loud for the radio during riding though....;0( need to figure out how to insulate it back up again...all the foam is gone in the engine bay.

i love it when i fix someone elses crappy attempt to fix something. makes me happy and feel far superior. ;0)

Pictures would be greatly appreciated, your boat sounds awesome!
