I have a 1973 Mercury Mercruiser with a 140hp engine and a 2:1 ratio. The boat weighs about 2400 pounds. It had the original prop on it until I wrecked it last weekend. I have the owners manual and the prop is listed in there. It's a 15 1/2 inch prop with 19 pitch. Heck, I can even tell you the original mercruiser part number. It's B-48-58-422A4. The number is listed in the manual and it's printed on the prop. Problem is nobody makes a 15 1/2 by 19 prop anymore. What do I do now? The nearest marina is 70 miles away and I can't afford for them to test the boat out and find a suitable replacement. Nor can I just start buying pops at random and hope I find one that works. Can anyone here tell me anything newer prop would perform the same as this prop did? If you can I would appreciate it. Or, am I totaled screwed.
