Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part from Aftermarket / Moto-Electrical, engineered to match the original manufacturer (Tohatsu/Nissan) specifications for fit and performance.
How do I know if it fits my vehicle?
Please check your service manual or original piston part number. This piston is specifically for the 3-cylinder 70HP, 75HP, and 90HP TLDI models. If your part number matches 3Y9-00004-0, this is the correct fit.
What does "0.5 O/S" mean?
It stands for 0.5mm Oversize. This piston is designed for cylinders that have been bored 0.5mm larger than the standard factory size (usually to repair cylinder wall scoring or wear). It will not fit a standard, un-bored cylinder.
