Saving Old Seagulls

Were the centres in both ends of the crankshaft there for checking the shaft or were they for centring that end of the crank with the centre on the inner face of the crank web for main bearing grinding & big end pin hole location,

That is a very good point Charles, One I did not think of.

Happy to give it a go. Let me know if you want to give it a try.

Do you have a lathe? If so put the crank between centers and do the test again. it would be interesting to see the results.

What cunning plan re the prop?

It could be sent to me and I can cast a new one.

I can use the old one as a pattern to make a new one even if one blade is missing.

Sorry Polybus, My bad! I miss read ant thought you had used a puller.

And now you know why Not to use a puller.... ever!

I would say just use a grinder to get the rest of the flywheel off, you can't heart it any more!

Have you still got the old one? Could it be rebuilt?

I didn't think there was any difference
I guess you are after the one with the red label?
This is mine after I rebuilt the mixer (thanks BnC) It lives in the lounge

So it the engine over heating when used on the boat or only in the wash down tank. is there a lot of water coming out of the tell tail or is it only a dribble? I have made a lot of props and tweeked all of them and loaded the engine up to almost the point of stopping, as long as you have good water ...

I would say have a look at the water jacket, I had the same problem and found the brass fitting was half blocked.

Keep at it I'm interested in the outcome.

I think I've seen that motor in New Zealand, at a place called Waiuku.

I think you are correct! I know nothing about though!

Plug looks good to me! Nice colour

Not me!
The shipping to New Zealand was too much!

Yes very simple and easy to work on.
