The cooling system might look weird BC it's connected to a hose right now? But the guy I bought it from said it is unique in that it does not run through the engine, so it can circulate seawater/freshwater... Not sure I fully understand but it sounds good.
SN reads 5236734 on the sterndrive...
Good tip on the fuel filter.
Someone else was saying the stern drive is actually a TRS, which maybe an older model of the Alpha. Here's the service manual I dug up:https://www.slideshare.net/jkmmemdd/mercury-mercruiser-stern-drive-units-tr-and-trs-1979-service-repair-manual-80794687
Just bought this SRV 240 last week. Trying to get some new parts for it but I'm having a tough time identifying the exact make and model of the engine and drive to get the right parts.
Here are some pics:
