?87 Suzuki 150hp?swapping lower units

[wjob]

Any one know if I can easily swap lower units between 1987 and 1989 150hp engines? Somebody told me I might have to first remove power head from 1987 and insert or modify something there before I can install the 1989 lower unit?

Several other questions:

1. What?s firing order on '87 150hp when standing behind engine, looking forward?
2. Are the electrical systems interchangeable between the ?87 and ?89 models?
3. My ?89 has a badly rusted steering arm, possibly a piece can be welded on but also considering finding a good used one and swapping it out? What?s involved to swap one out?

thanks
Bill

A manual would be of great help to you.
Go to brownspoint.com. There you can compare parts and numbers for the different models.
You may have to replace the shift rod. If that is the case the power head has to come off.
To replace the steering arm the power head has to come off.
If this motor has been near salt water you can expect bolt shearing problems.
