Compatibility / Fitment Guide
| Verified Yamaha example | Fitment condition |
|---|---|
| 90TLR, 2006 and later family | Parts diagram must list 6D8-44341-01-CA / matching housing set |
| F75LA / F75TLR, 2006 and later family | Confirm lower-casing diagram and four-bolt/gasket pattern |
| Legacy 75 / 85 / 90 two-stroke family | Only where 688-44341-00/01 or a documented 6D8 supersession appears |
| Selected F75 / F80 gearcases | Exact model and serial-specific diagram required |
Physical check: compare the old housing's four mounting holes, centre bore, water-channel opening, O-ring groove and both gasket profiles with the photographs.
Exclusions: Parsun or Hidea compatibility is not guaranteed by brand/horsepower; use only where their parts information cross-references the same Yamaha housing geometry. This is not a complete impeller kit.

Frequently Asked Questions

No. Confirm the exact housing number and gasket pattern in the serial-specific lower-unit diagram.
Is it genuine Yamaha?
No. It is an aftermarket housing kit.
Does it automatically fit Parsun or Hidea?
No. Fit only when the parts data and physical housing pattern cross-reference exactly.
Note: Inspect the mating surfaces, pump cup, impeller, driveshaft and water passages during service and use the manufacturer's gasket orientation and torque sequence.
