| I just recently purchased a 76 ski Tique that the previous owner let the engine freeze and crack the block. I think I have found another block but I am having trouble finding the 2 piece rear main seal for a reverse rotation engine. Any suggestions or help would be greatly appreciated. |

I question that part number because Summit,O'Reilly's,Jegs,Advance etc all show that it is available but in their description does not list reverse, only marineengineparts state it is. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

This may be rather silly of me, but the 2 piece rear main seals are smooth and the oil control/wick/helix lines are on the crankshaft so why spend the bucks on a "marine" seal when you can use an automotive 2 piece seal for quite a bit less money? What year block are you looking at?

If you look it up by part number all except eBay are within a few dollars of each other - eBay is 10 - 11 cheaper. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

But if you look up a rear main seal for a 77 ford 302 and come up with a FelPro part number like BS30136 or 2901 for example, it's a bunch cheaper. (edited to add the 2901 seal) Must be paying for some "marine rubber"

I wonder what the difference between the two is- Felpro is not calling it marine ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1711&sort=&pagenum=1&yrstart=1966&yrend=1970" rel="nofollow - 69 Mustang HM SS 95 Nautique Super Sport |

Using Summit prices for consistency Felpro 30136 not labeled marine...... 18 dollars Felpro 2901 not labeled marine.........27 dollars I think you're paying for that word

| Must be safe to assume you're looking at a block built sometime before 1983? |

| Yes I am looking for a pre 1983 block |
