1965 west bend 450 45hp turning over problems

I’m having a hard time trying to get my 1965 west bend 45hp outboard to start. My starter is barely able to turn the engine over and once it hits the compression stroke it struggles. I currently have a new replacement starter that replaced the prestolite starter than was on it when I got it which was doing the same thing as the new starter. I think it’s an engine problem not the starter. The exhaust is not clogged, and Everything looks good but I can’t figure out why the starter cant push through the compression stroke. Any help is appreciated.
 
Low compression on one or more cylinders can cause hard turning.
Bad bearings in the block and lower unit can also cause the problem.
Pull spark plugs and see if that makes a difference???
Drop the lower unit and see if that helps???

I’ve got high commpresion numbers. At the moment I can think of them but I pull both plugs out and it turns over great. I put one plug in and it struggles. I will remove the lower unit and see what happens. I’ll keep you updated
 
The comp #s need to be real close to each other.
It can be 160# or 90# just need to be close.
Any more than 5-10# can indicate problems.
The power cable: check it for bends, swelling along the line and the connectors are bad??
 
140's great.
Then the starter or the battery cables might be the problem??
A new starter can be defective??The cable ends check for corrosion or swelling along the cable.
