Check out the lower unit pictures on this site. All of the early K Models
has water pumps although of three different designs. Post war KD Mercury
and WD,WF and WG models have the third design.
There are air cooled outboards such as the prewar Bendix and postwar models
made by a number of makers and sold under various brands.
The short answer to nate's question is yes. Don't crank it out of water.
I can't get the prop off I've done it a couple of days of go and it came out without a problem. The second time around I have taken out 4 screws but it won't come off.
Four Screws? Please explain.
Prop is held on prop shaft by the acorn nut on end of prop shaft.
Corrosion is not likely issue if you have removed prior.
Did you find a washer and rubber bushing under the acorn nut?
Often the washer has been replaced with a standard washer which
has too large a diameter which can be jammed into recess at rear of
propeller and cause a problem to remove. That may/may not be the issue.
To combat corrosion preventative maintenance called for grease to be
applied to prop shaft anytime prop or water pump was service or annually.
Seldom done if my experience is any indication.
I'm attempting to clean the water pump and I removed 4 screws around the prop area that are the pump/prop onto the lower unit of the outboard. There is a slight opening between the water pump and the lower when I remove the screws but it won't come out readily. Did I possibly reassemble the water pump/prop back on incorrectly by not lining something up correctly. If that's the case then I'm screwed. The crank shaft is still moving when the prop is moved which gives me hope that I didn't break it. The new coil came in today so I plan on a test run tommorow.
I put the new coil in today and the ohms meter is transferring electricity but there is no spark, what are some possible issues?
It would be helpful to see picture as I can't see what you are saying regarding
the water pump/gear case/prop shaft/prop difficulty. I have been called dense.
The brass plug in gear case is almost always fused to aluminum gear case by
corrosion. If stuck best to leave it be.
