bc: Now that you have found the dipstick you can see how small the opening is on the early model. About the size of a pencil. I use the hand pump near the carb for oil changes. By adding a short piece of hose to the hand pump you can make things much less awkward.
Yes. As best as I can tell the early models did not have a T-stat so "raw" water, what ever the boat is sitting in be it salt/fresh/polluted fresh/brackish, ran freely thru the A-4. Some folks used a recirculating loop to route some of the hot water back thru the engine. This valve gives you some control over the operating temp but must be adjusted manually. Then the Dole T stat was offered as a aftermarket upgrade and allowed for hands off temp control. You can see what it looks like on the pictures sent earlier.
Check and see if you have the Dole housing and we can go from there.

Edit: +1 on what Sam said about refilling the oil slowly.
