Firstly love the forum information. I have recently bought my first boat came with the above motor long shaft I think the numbers are not very clear I think the serial number is 8023229 if I can have the year it be awesome so I can chase a workshop manual. Another issue I am having is the engine start first go but doesn't pump water out. Just playing around with it I took the water outlet hose off the body and sucked on it. After that there way excellent flow of water. I have to do that every time I restart motor. Could this be a water pump issue or some stuff is blocking the out let. Apparently the engine was rebuilt 10 hours or run time ago. Thanks for the help

Alex;

Where are you from?

Engines beginning with an 8 were built in Australia.
