2001 Mercury 25 hp 4 stroke MID section removal
Hello all! I just picked up a 2001 Merc 25 hp 4 stroke Big Foot that has is giving me no water flow through its tell tale hole. After hours of problem shooting and dismantling I am now stuck at this point...
Power head has been removed and cleaned out, thermostat replaced and exhaust cover taken off and cleaned out, lower unit has been removed and water pump repaired (the old Impeller was fine but there is a new one in it now).
I am now almost certain there is a bad gasket right at the top of the water supply tube that is in between the top of the driveshaft housing and the adaptor plate. I attempt to shoot water up the water tube but I only get a small trickle of water up through the adaptor plate. Now here is the question... I have all the bolts off the adaptor plate and all bolts from the bottom of the driveshaft housing but I cant separate the two from each other! Is there some trick I'm missing???
Any help will be appreciated.
