Boat is a 1999 we think from Hin no
What was the original engine fitted in these please

Currently has a 5.0MPI V8 reporter engine

Trying to work out the gear ratio of my drive,no serial no. Stamped on it

Could have been a 4.3, a 5.0 or a 5.7 fitted originally. See the chart below on how to identify gear ratios

Thanks for this. But unfortunately. There is nothing to indicate any serial numbers or anything. On the leg or anywhere else. The engine has been changed and the serial numbers on what we have do not match up. Obviously we don’t want to order the wrong drive.
