Earlier model R, MR andAlpha One, as well as Bravo drive units, use theshorter trim cylinder. DO NOT attempt to substi-tute trim cylinders or damage to drive unit and/ortransom assembly could result.

Trim cylinders can be identified by a casting numberon inboard side of trim cylinder.

Shorter Cylinder: 98703, 98704, 98703--1,98704--1

Longer Cylinder: 14034--1,14035--1

! CAUTION

Ensure work area and all components are clean

before reassembling trim cylinders. Power Trim

components can become damaged if dirt getsinto system.

NOTE:Before reassembly, lubricate all internal partswith Quicksilver Power Trim and Steering Fluid orSAE 10W-30 or 10W-40 Motor Oil.
