Problem fixed: Poor water pickup. Not much water coming from the tell tail.

Removed gearbox lower leg to replace water pump. Replaced pump and gaskets. Although the gear was left in neutral, I found it difficult re-locating the drive shaft and gear selector into the power head. Found it slipped in easlily when the engine was turned upside down and shafts lowered verticall downward. Also removed the exhaust cover outlet assembly and de-clogged the water valley area. NOTE: This motor is susceptable to salt clogging because it is difficult to properly flush the motor with fresh water. "Ear muffs" can't be fitted due to the location of the water pickup. Circulating the water in a bucket or tank/drum can be limiting to correct flushing. Also replace the clogged thermostat which had also suffered from salt corrosion.

Problem fixed: Lost Key, ignition switch replaced

Not a difficult job replacing the ignition switch but I had to remove the starboard seats in order to access the bolts holding the remote control box which housed the ignition switch.
