Im having a bit of trouble with my motor,annd I know this is a topic thats been discussed alot.I have a 1979 175 hp black max 1750.The problem has me shaking my head.
I had no spark at all in the bottom starbord cylinder,I changed the coil and now have spark[second time in a year].I put a timing light on to check all the cylinders,The middle and lower starbord cylinders seem to have a weaker pattern than all the others.I swapped the stator wires on the blocks and the problem did move,so Im asuming its the block.
Is there a possibility that theres a trigger problem sending to much voltage to the coil and blowing it out?The other problem is when I checked the serial # it comes up as an international engine that can have 3 different stators.The one tell tale sign is if it has a voltage regulator on it.I can see something that looks like it can be it mounted under the starter selenoid with 3 wires coming off of it,but Im not sure.Id like to get back on the water asap so if anyone can help me Id apreciate it.
Thanks
