It sure looks like you solved a problem I had with timing belts in the early 70s. I found that I couldn't get timing belts without excessive slack. This made accurate timing impossible. Your setup looks to correct that issue.

In the older Mercury motors like the 44 ci 50 I found going up to double oil in the mix worked very well. These motors didn't need as much Octane rating as the later designs and the extra oil seemed to help with ring sealing and prolong the life of the rings and bearings. We often ran these motors several hours on a typical race weekend and endurance races of 3 hours or more were common. If I managed to avoid getting the motors wet, losing a water pump or getting torn down at a race these motors would run a couple of seasons with only basic maintenance.

25 to 1 sounds about right. By the 70s they had all gone to 50 to 1. I don't remember exactly when that took place. The claim was that the oils were better so less was needed. I just kept running the new oil at the old ratio and never suffered a lubrication related failure. The most common problem was sticking pistons due to water pump failure or water pickup issues. The older motors with the solid flywheels wound break the crank right at #1 throw but the flexplate flywheels cured most of this problem. Some guys had problems with reed failures but for some reason I never had one fail.

I ran OPC stuff back then and we had to run stock reeds at the stock reed stop settings. One of the first thing an inspector looked at on teardown was the reed blocks. I have heard that reed failure could be related to driving technique. Large and frequent throttle changes can lead to premature reed failures. I do not know if there is anything to this theory however.

3rd Gen, would you consider bringing yourself and your T2x tunnel to an APBA Vintage and Historic event? You and your rig would fit right in; we would love to have you as part of the group. Email me for details (jtigerjr@hotmail.com) if you're interested.

Very cool Ed, I'll look forward to your email. I do remember meeting you a few years back up in Hague at Rogers Rock, and indeed it would be great to see that T2x running after hauling it's parts all that way. Thank you also for your kind words on the Propeller story. BTW, that story is actually a reprint from an article I wrote for BoatUS Magazine.
