Polaris engine problem?

Hello,

I am thinking about buying a Polaris Genesis I, 2001 model. The unit had a
warranty repair. The piston and connecting rod were replace due to oil
starvation. The unit has only 18 hrs and good condition.

I am not familiar with PWC engine. Is this a bad sign that I should stay
way from this unit?

I appreciate your PWC advice.

You can't replace the connecting rod on a watercraft engine because the
rods are pressed onto the crank and it becomes an assembly. You need to
find out what the total repair really was (crank/piston/cylinder/head)
and why it happened (did the oil line come off that one cylinder -
otherwise, hard not to affect the other two cylinders if an oil pump
failed). Lots of times, the shop assumes it knows the problem and fixes
the damage without fixing the cause. It's not necessarily a bad thing
if it was diagnosed and fixed properly, otherwise it can be ongoing
headache that you don't need.

The FI had multiple problems starting with
a very cheap terminal board in the electric
box. They also had some problems with
the timing of the ficht causing a lean
problem at certain RPM's. They either
had a intake or exhaust manifold to fix it.
If the unit does not have a warranty I would
steer clear. The unit also had issues with
the stop start switch, stator, and CDI.
Get the drift.

Hi,
Called the dealer who repair the unit. They were not very helpfull. They
suggested that I bring in the unit and let them to a complete evaluation for
$70. Another way for them to make money.
