1992 Mercruiser 4.3 Alpha 1 Gen 2 cam shaft plug install

[nic420]

I rebuilt the motor, installed it back on the boat but forgot to put in the cam shaft plug back in. Found out while braking in the motor and noticed a leak by the flywheel. Motor runs awesome! I was wondering is there an easier way to install the plug without completely raising the motor from the engine mount or taking the motor out of the boat? Tire now and just want to see her run.

drive off, motor at least up to work on it. remove rear housing, coupler, flywheel, replace cam plug

what else did you forget?

motor at least has to be pulled out, FH and FW removed to get access to back of block to drive in and seal the welsh plug at the back of the cam bore.
