[avasdaddy]

I just bought a 97 seadoo sportster today in really good condition, not excellent but good. its a single 85hp motor. what could i expect to get to sell this boat in the central pa area....any offers i am accepting best offer

 

[deepdiver]

Sad. You just bought it and didn't even use it?
I have no idea about prices but hate to see this as a "flippers" site. This is a users site.

 

[avasdaddy]

how about you check my profile man. i have 3 seadoo jet skis and a seadoo challenger completely re-done... thanks anyway and thanks for wastng mine and your time commenting

 

[deepdiver]

Sorry to offend you. Your profile doesn't show any ownership, otherwise I would have seen it. Good luck.

Relax...

Arguing on a chat board is like a monkey poo fight. Funny as hell, but doesn't' accomplish anything.


OK... a Sportster in good condition will get you $3000 to $4000 dollars. If it's the original engine, and has some cosmetic flaws... a little less.

We are on the back side of summer here in PA, so if you can't get it sold in the next couple weeks, you will be better off to sit on it until next spring. The price will be prime as the trees are just starting to turn green.

Yeah I agree with Doc, somewhere around $3500 if it is in good shape. What kind of bargain did ya get?

 

[avasdaddy]

i was planning on taking 3500 but i got it for 900 cause it wasnt getting any spark. the coil is getting 24v but nothing coming out of it. guessing the cdi box?? its at me buddys house who is a mechanic.

 

[seadooya]

if you got volts at the coil, and nuth'n out of it, trim the plug wires and/or replace coil.

 

[RFoster130]

Wow 900 is a bargain if you can get it running fairly cheap.

 

[Dr Honda]

A 720 CDI is a high voltage system. You should see +120v when the engine is cranking. The wire from the MPEM that connects between the CDI/coil pack, and the mag is just a "Kill" wire. ( It grounds the CDI) if you disconnect that wire... the MPEM will have no effect on the ignition. Pull that wire, and see if you get spark.

Don't run it that way. The MPEM is your rev-limiter. If you try to run without a rev limiter, then you could kill the engine. BUT... that will verify if you MPEM is the problem.

i should of mentioned which i forgot the key wont beep when i put it on either..

 

[avasdaddy]

so i found that the person who had the boat before me took out the beeper so i replaced it and it does beep everytime. the boat still cranks but wont start. i ohmed out the stator and it had 55.6 ohms but not sure whats correct? any suggestions on what to check to see why i still am not getting spark....is the only way to check the wire running from the mag to cdi is cutting it? is the wire black with a red/green chaser?

 

[avasdaddy]

also is there a way to test the coil with an ohm meter

On a 720 engine, the mag coil for the ignition is 40 to 70 Ohms. So, that is fine.

Unfortunately, no... there isn't a way to test the coil since it has the CDI built into it. To test it, you need an ignition testing tool that is a "dealer only" tool.

But, I will say this... you shouldn't be seeing any voltage on the wire going back to the MPEM. Did you try to disconnect the MPEM from the black/red/green wire that goes from the mag, and the CDI/coil yet?? If you have that disconnected, and you still don't get any spark, then I would say your CDI/coil pack is dead.


If you need a 720 CDI/Coil, I have a couple. (PM me if you would like to buy one) If you are local to Pittsburgh, You can come to my shop and I can let you test your engine with one of my CDI's.

 

[RFoster130]

Have you taken the plugs out and grounded them while cranking to see if they are getting any spark at all.

 

[avasdaddy]

do i have to cut the black/red/green wire to disconnnect? also, i did ground plugs... dr honda how much do you want?

 

[Dr Honda]

PM sent.


No... the wire will unplug somewhere in the electrical box.

 

[avasdaddy]

I disconnected the black/green/red wire going from coil to the mpem and it starts right up now.. does this mean the mpem is bad? if so does anyone have a working mpem available? does the mpem control timing or can i bypass it with a toggle switch?

 

[Dr Honda]

The MPEM does not control timing, but it is the rev limiter. If you try to run without it, and the pump comes un-hooked (cavatation, or bouncing out of the water) you could pop the engine from over reving.

I don't have an extra MPEM, but you could wire in an aftermarket MPEM for a ski. (they are around $200)

 

[avasdaddy]

ok thanks drhonda. i spoke with 3 dealers in my area and they want over 900 for a factory mpem...i was thinking screw that haha. i was also told by one of them that the mpem did control timing but for 200 dollars i will most def. put that in. where can i find that part?

 

[avasdaddy]

so i go out to start the boat today to see if i cant find anything else out and it wouldnt start with that wire disconnected so i connect it and what do you know it fires up and turns off with lanyard on and the push start... it did not work like 1 out of every 5 starts without disconnecting the wire going from coil to mpem....any ideas??

Well.... that dealer was an idiot, but most likely you were talking to the parts guy, and not a mechanic. On the 800 engine (challenger) the MPEM controls timing. But the 720 is a self contained CDI, and the only thing the MPEM does is to kill/stop the engine. (and it's rev limiter)

I'll PM you since the source for the aftermarket MPEM's is not allowed to be posted.

Bad MPEM. The will go intermittent sometimes. Since it uses a transistor to "Kill" the engine... since you told me that there was voltage on the kill wire... I'd say that the transistor has gone bad.

 

[avasdaddy]

ok. the sportster works great... i had it out today side by side with my challenger and i am concerned about my challenger because i have brand new solas impeller and brand new wear ring and drive seal and for some reason my sportster is running faster out of the hole and top end than my challenger.. the sportster hit 43 on gps is that about right? i had it out two days today without a single problem...boat is going for sale for 3600obo...any ideas on challenger? its got 160psi and just changed plugs it sounds good and the whole out drive is new so i dont understand it.. carbs are clean
