I've just recently acquired my father's old '84 Hunter 34. Which had an owner between us. The boat went through Hurricane Katrina unscathed, the previous owner had the Yanmar 3GMF rebuilt. Im currently trying to get the motor turning over. I believe the pistons are seized possibly due to water intrusion through the exhaust during another hurricane we had that the boat may have been tied too tight with the rising surge.
I've pulled one injector but the other two are stuck. I tried bumping the starter but it won't turn over. I tried spinning the crankshaft by rotating the pulley nut clockwise.
I've read here that putting a diesel/oil mix in the cylinders then trying to spin it by hand may work?
Where can I get the special Yanmar injector pulling tool?
Is it possible for water to have risen into the exhaust and into the cylinders and caused them to seize, it's been about 3 years with zero activity. What else should I be looking at rebuild wise?
I hate to pull the heads and all since it was just redone.
Thanks!
