Trim Cylinder Assemblies
    Pre-Alpha and Alpha One Trim Cylinder Assemblies

Before you order your trim cylinders and hoses you will need
to read the casting number on the side of your cylinder housing.
The casting number is on the inward side so you will need to remove
the cylinders from the drive unit to read the number.

Early trim cylinders were narrow and they had knurled end caps.
These were typical for 1981 units and older.
Both the port and starboard cylinders were identical and all
four of the trim hoses were the same length.
Old Style cylinders used Hi-Pressure-Low Volume trim pumps.

Mercruiser then came out with the fatter trim cylinders in 1982.
The fat cylinders use Low Pressure-Hi-Volume trim pumps.
The reverse lock valve is built right into the pump.
There is a casting number on the inward side of the cylinder.
Early fat cylinders had a casting number of 98703 or 98704.
It is important that you know your casting number because there
are now two different length fat trim cylinders.
Also, the port cylinder is not the same as the stb cylinder.
