2004 Yamaha 40 hp trim and tilt shaft

[pstephens46]

Fairdeal has an F225. Completely different model, with a completely different trim and tilt unit, than is the OP's model and unit.

OP's model has but one cylinder and one piston. Fairdeals has one tilt cylinder/piston and two trim cylinders/pistons.

Op's uses a piston within a piston within a cylinder.

F225 tilt piston on the left. 40 tilt/trim piston on the right.

I should have been more clear in my response to Solo's comment. I was referring to the F225 he and Fairdeal both own.
