Freaky, settle down ole mate ..... there never was 2 washers used in the "Seadoo" rod swap @ top end. REMEMEBER it is crank guide not piston guide.  They may be needed when using his 1mm O/S piston  ???

OldFart is right, the 1mm oversize piston kit includes extra washers(spacers). The first run of pistons had a larger pin opening boss than the OEM. The second run will have the same opening as the OEM. I should have the improved rod kit out soon.
