Stripped it down - I can confirm the drive shaft oil seal and ball race behind the top vent hole does completely prevent ventilation. Thus the...
- well I wanted to know what was wrong - but there are other things more interesting to take apart . . . no, it was just servicing through...
Yes it is an older motor because pics of the later ones show the impeller/ water pump sited behind the prop instead of at the top of the gear...
Thank you for the manual westvanhan, now on my desktop. The water pump is at the top of the gear housing on this model. I've separated it from...
Good thinking Barry. As mentioned I poked a thin wire into the top hole and it would not go right through. Which is why, in my ignorance,...
As I mentioned above the old oil is not milky just darker with no obvious particles or sludge. This model has the impeller in a housing at the...
I can pour the oil in the bottom hole with the box upside down but how do I fill to the correct level? I would like to fill it as it should be...

Thank you gentlemen. I read the Mercury warning buzzer only operates for low oil not it's output. There is a section in the manual which...
I am grateful for your work gentlemen. However I feel as it's no. is 'SH' it may be the Shawnee also the Signa looks a little too posh to be...

Any idea which model my Thunderbird is? serial no. - SH 66105 Max H.P. - 75 capacity - 1000 I tried everywhere, maybe the my UK boat is...
Thank you for the further information with steering which I shall experiment with. The steering has no play and I have changed the toe in in...
Thank you for your information, jehardiman. My boat does not have rudders it is a twin outdrive. My thoughts on the matter were brought about by...
