Trim System
EMP Trim Cap & Seal Kit - 8985P
High-quality EMP aftermarket Trim Cap & Seal Kit for BRP E-Tec Inline 3 and V4 outboards.
Replaces OEM numbers 0769114 and 5008985. Excellent solution for common trim leaks and pressure loss.
Compatible Applications
BRP / E-Tec Inline 3 & V4 outboards. Verify with your engine model and serial number.
Common E-Tec Trim Pump Issues
- Fluid leaks around the trim cap — most common symptom of failed seals
- Trim drifts down after raising — pressure loss due to bad seals
- Pump runs but trim is slow or weak — air entering through worn seals
- Noisy or continuously running pump — low fluid from leaks
Replacing the cap and seals with this kit often resolves these issues.
Installation Guide
Tools Needed: Socket set, torque wrench, gasket scraper, clean rags.
- Let engine cool. Support the outboard and relieve hydraulic pressure.
- Remove the old trim cap and clean the mating surface thoroughly.
- Install new seals and cap. Torque to factory specifications.
- Refill hydraulic fluid and bleed the system if needed.
- Test trim operation and check for leaks.
Refer to your BRP service manual for model-specific details.
