You are wasting your time with WD40. 

WD40 is a 'Water Dispersant' - Hence the WD - (blend no 40), It is not a pentrating oil and has very limited 'oiling' properties.

 

You need proper penetrating oil, save your WD40 for what is was designed for - getting water out of electrical junction boxes.

yeah I didn't know until my friend said about it.

Looking back at the photos as Tracy D'arth says the engine does look particularly rusty. I also see that it is a heat exchanger cooled engine. Is it used in salt water conditions by any chance.

That explains things a little more. I really think you'll be very lucky to get it moving successfully. It will probably need the parts replacing.

It is an unusual problem that I've never seen happen before. The only thing I can think of is that the o-ring, item 18 in the diagram has failed and allowed water to enter between the spindle and bush. Thats only a guess, but I can see no other reason.

when I got the boat it was filled with rain water, after it dried run fine. but during lockdown my float failed drained the batter and filled with rain water again, it was over the starter motor so that area would of been under water with a lose nut

The loose bolt would make no difference to the water getting in. All that bolt does is hold the speed control lever in position. The spindle is held into the sleeve by the internal bolt.

As I have said previously, that's the way it comes out. But unfortunately you need to remove the timing end cover and remove the internal lever and springs, then it is clear to come out vertically from the top.

Its the cover at the forward end of the engine. You will see the crankshaft pulley coming from the centre of it. This pulley will need to be removed first. It is held on with a left hand thread bolt.
