bendix is very reliable especially on the 4tec, have only ever seen 1 or 2 with a bendix problem, normally it is something else like sc bearing failure, timing chain failure, valve issue, etc. removing the bendix is a pain so I would make sure that is your problem, you have to remove the pump, driveshaft, sc, pto housing, flywheel, just to get to it.
what exactly is your ski doing?
