## Specifications

### Identity
- Brand: DVPARTS
- Model: 320788
### Dimensions and installation
- Weight listed: 3.52 ounces
### Part references and fitment
- Part numbers listed: Part Number：320788 0320788 FSM065
- Broad compatibility claim: Compatible with Evinrude Johnson outboards from the 1978-1990 and newer with 65, 85, 100, 115, 140, 150, 175, 200, 235, 250 HP

## Before you buy

- 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.

## 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.
