Hi<br />I recently purchased a used speedboat on ebay.<br />It has a 50 hp engine i was told but who know's.<br />The plate with the serial no is painted so i can't find out the age.<br />Anyway after fixing the pull start(job and a half after welding etc to get spring working again) i run it up with rabbit ears to try and flush. Noticed no water coming out of any holes and im not sure of where they should be i can only see 2 tiny little holes.<br />There is two silve screw ,one says flush and one vent.On the other side there looks as if a small screw is missing other end of prop.Anyway after running it for about 5 mins i noticed the head was hot and steaming so i decided the water pump can't be working.Decided to drop the lower unit to have a look.By the two bolts on either side behind the bolts 2 holes that i think must have worn away with the use of spanners. Should i fix these ?? or will it not matter.I Noticed no oil in the bottom part as i think there should be? Right at the back closest to the transom is what i think is the water pump.Is it driven by the connecting rod above by the engine? I just want to know if im not barking up the wrong tree.<br />Ihave got a manual comming i just want some insite before i do anything else.<br />Thankyou from LONDON ENGLAND
