Curious if I am doing something wrong here, because I haven;t gotten replies on my last two post concerning this problem. I've read the forum rules and have tried to follow them. I've checked all the topics on this forum and read numerous posts but can't find anything similar. Is this just too old of a boat or too hard of a question or am I breaking some forum code of conduct???
Hi Finnegan70, No it's nothing you've done as to why the low response to this type of question.. One of the main issues is that the detailed internal workings of the TR/TRS style drives isn't as well known by most forum members and if you didn't work exclusively around this design drive and/or own one (or more) nor didn't perform your own heavy service work to it, it's sort of hard to try and give detailed information about the internal workings of it especially over a forum mainly due to their complexity over the standard designed stern drives out on the market such as the Alpha and Bravo stern drives from Mercruiser.
Mercruiser had other high performance drives as well but they're typically not brought up that often nor talked about too much on boating sites such as this one. iboats tends to be more centered around typical recreational type boats for local lake type boating vs performance type boats or heavy work load type boats that tend to require more of the use of the TR style stern drive.
iboats used to have a member or two that could help give some good advice about the TR drive but I haven't noticed them posting in quite some time now. TR drives do tend to come up from time to time on another boating forum called Offshoreonly and there are a few members that known some general basics of how it works enough to talk about it some as the members either were or still are owners of the TR design drive... But even still the topics do tend to go quiet kind of quickly sort of like what is happening here.
Wish this old Merc master tech still posted as he was a good knowledgeable guy with the older stuff like what you have as an example,

I can say for sure that this design stern drive would not use a shear pin where the prop contacts the props shaft. The prop hub would be of a solid hub design and even solid hubs will eventually slip to where the hub inside the propeller would need to be inspected and changed out by a propeller repair shop set up for this kind of difficult work.
Here's going to be a parts catalog for the TR stern drive of your year and size for you to look through as to see how the parts would work together....

The next step would be to find a service manual for both your engine and stern drive and start studying it the best you can for a better understanding... The trouble shooting section would be the first place to look at within an OEM service manual.
I'm also going to go-ahead and merge your other topic here with this one as maybe it will help gain some other type interests or traction for you.
Hope your problem isn't to severe and please keep us updated as you tend to find out more of what seems to be happing as while we might not be able help as much as we would like to, we still like to read how it's all going on your end.... Good luck to you with it.
