Gday to you all out there. Now I have a little problem which I need some advice on. I acquired an older 8hp Mariner which hasnt been used for approx 8 years. I did the right thing and pulled the spark plugs lubricated the cylinders etc and pulled it over a few times all good. I took the leg off and checked the water pump all good. Time to see if it will run. Using a pair of muffs I gave it a couple of pulls and it started straight off. Problem; there is only a dribble of water out of the pisser. I took the leg off again and attached a water hose to the pipe which comes from the pump still no real water. Question how do I clean out what I assume must be a blockage in the block? Any advice appreciated. Regards Thommo From Tasmania; way down under.
