What to know before buying
Listing details to confirm
Fitment claims are inconsistent: the title says Johnson and Evinrude 60–300 HP, a feature lists 65–250 HP and years 1978–1990 and newer, and the detailed application examples focus on particular Johnson models, mostly from 1976–1983. Confirm the exact outboard and trim-unit model before purchase. The broad Evinrude compatibility is not substantiated by comparable model-specific examples in the supplied details.
Who is it for?
A good fit for
- Owners identifying a replacement by 320788, 0320788, or FSM065 who can verify the part against their outboard's trim unit.
- Repairers of Johnson power tilt and trim units whose exact model appears in the listed applications.
Less suited to
- Buyers who cannot confirm their outboard and trim-unit fitment from the supplied model-specific information.
- Those seeking a full trim-cylinder repair kit, since this listing identifies an end cap assembly seal rather than a broader kit.

Frequently asked questions
What part numbers does the listing associate with this end cap seal?
It lists 320788, 0320788, and FSM065. Compare these with the existing component and your outboard's parts information.
How should I check whether it fits my outboard?
Verify the full engine model and the power tilt and trim unit against the model-specific application details. The listing's broad horsepower and year claims do not fully agree with one another.
Is this listed as a complete trim repair kit?
No. The product is identified as a trim-cylinder end cap assembly seal. The supplied information does not specify a broader repair-kit bundle.
