Chrysler 100hp tilt trim operation

[lund101]

I have a new to me 1980 Chrysler 100hp outboard with factory controls, my question is how do I trim the motor, I can tilt the motor with the switch on the gear/throttle lever, but haven't quite figured out how to trim the motor, can't find any other switches for this. Thanks

Re: Chrysler 100hp tilt trim operation

If you only have one cylinder that looks like a shock absorber and only two hydraulic lines, then the engine is tilt only. This cylinder will be inside the engine mounting clamp on the hydraulic motor side. There usually is a plain shock absorber on the other side. If there is a large flatter pentagon cylinder with five bolts holding on the cap, centered between the engine clamps in addition to the tilt cylinder, and four hydraulic lines, then you have tilt/trim.

In the case of tilt/trim, the first movement is the large cylinder and this adjusts trim. If you hold the switch past the trim up limit, then the engine will start to tilt. Tilt is not powerful enough to move the engine while operating the boat at more than about 1000 to 1500 RPM.
