Suzuki tilt question

Our 5 year old boat has a Suzuki 90 4 stroke. When we tilt the motor down, there's a point where part of the motor seems to engage with the mounting plate, maybe the alignment's a bit off, and it moves a lot slower for the last 20 degrees or so, maybe due to friction. Is this intentional, or does it sound like there's something wrong with the mechanism?

Thanks

It's the way the tilt/trim mechanism is intentionally designed, in two stages.

The tilt phase swings the motor's foot up and down while out of the water for storage at various angles, and moves very quickly.

The trim phase adjusts the motor trim once the motor is mostly down. It is a fine, slow moving adjustment, designed to be precise, and capable of being adjusted while the full force of the engine's power is applied through the foot.

The tilt and trim functions operate with one following the other and are controlled by the same lever/switch in the control console.

Each function has a pair of hydraulic cylinders that accomplish the desired adjustment in balanced form. Take a look sometime. Long narrow ones for tilt, short fat ones for trim.

You motor is just fine, and as it was designed to be!

Thanks! That's good to know.

I figured it might be a fine adjustment, but I noticed it only slowed down after part of the motor bumps into and then rubs along a part of the motor bracket, kind of like closing a bent staple remover.

One less thing to think about.
