1989 650 jet ski starter drive spins but not turning motor,drive is working fine when removed.

there are no gears just a direct drive from the crank to a jet pump ! if theres no propultion of water it could be several things !
1. plastic bag etc in the intake to impellor pump assy !
2. impellor gap to housing too much ie worn impellor !
3. impellor not turning because splines on either the shaft or impellor worn !
4. drive coupler damaged and spinning on shaft !
Try running on a hose pipe and look at rear of engine ( remove plastic cover so you can see the 2part coupler and drive shaft ) .
Check the impellor assy !

no i do not know where to download it from but its easy to do
there are two different starter solenoids and you will need to know this information before ordering a new one
so follow these instructions and it will be easier for you

DESCRIPTION
a solenoid is composed of copper coil windings
with a metal projectile inside
when a electrical current is passed through it it turns the metal projectile into a negative magnet and shoots it into what ever it need to move

(1) is pre engaged and is connected to your starter motor
and will take quiet a bit of knowledge and quiet a few tools to disconnect the starter solenoid from the starter motor
these are designed to make it harder for the diy mechanic to work on
so that you have to spend money in a work shop getting it repaired
most machines now days are fitted with this type of starter

(2) is a normal starter solenoid and stands alone
you will need to find this out before you replace it
and obtain the new starter solenoid from your local dealer
and make sure it is the right one for your (wet bike / jet ski)
these are designed for the home diy mechanic
and are very easy to replace

LOCATION
if it is a pre engaged type
from your main live battery terminal there will be a long red cable that goes direct to your starter solenoid that is attached to your starter motor
disconnect your main red cable and the two wires
undo your starter motor complete it will be easier to work on
may be dearer but easier to replace the whole unit

the non pre engaged type
your normal starter solenoid will be close to your battery normally in a rubber housing of some sort
the solenoid has two main live polls (one main cable goes to your battery with a label mark this with BATT)
(the second main cable goes to your starter motor with a label mark this with START)
and two wires coming from it (they go to your starter button)
and is placed between your battery and your starter motor

SOLUTION
make sure your battery is disconnected and both live and earth cables are undone and disconnected and remove the battery
your main RED live wire from your battery
follow it until it attaches to a block that block is your starter solenoid
disconnect the block by undoing both the nuts that hold the cable in place on the polls
disconnect the two wires
and replace in the same position as the original one
reconnect the cables and the wiring in reverse to the way you took them off
reconnect your battery
and start up

hope this info is ok
good luck

if its xlt 1200 its inside the big black electric box at rear of engine ! unbolt it and remove the back cover !

bendix gear stuck or broken !

is the starter button putting out power to the starter?

To get access to the starter you will probably have to lift the motor out of the machine. Most Kawaski hulls do not give you much room to work. When you take the exhaust off you may have enough room to unbolt the starter.

Unbolt the electronics box (swing out of the way), take off the box mount plate, and remove the exhaust upper manifold and expansion chamber. This should give you good access to the starter.

The seals in the drive pump can be replaced by taking off the ride plate and pump housing. To replace any other seals (engine or hull) you will have to remove the motor from the hull.

take the spark plugs out of the engine and try to spin the imrellar shaft it should spin fairly easy and yes jet ski motors will freeze and bust most shops tell u that u only have to blow them out this is not true u need to run rv antifreeze thrught the engine in cold temps but you may have a froze impellar bearing that will bind up your motor take your whole impellar assembly out and try to turn the motor and see what happens

yes but its not easy you pretty much have to take all the exturnal parts off carbs, exhuast airbox if u have one but it can be done make sure you have a swivle for your socketsbest place to get a starter is sbt.com short block tech
