More boat woes with my PCM powered Mb Sports boat. Just before purchasing, the previous owner had a new steering cable installed. To do so, the tech removed the engine. It appears that, when he reinstalled the engine, it was installed too low when lined up with the driveshaft. After trailering the boat and running it a total of a few hours, a tracking fin bolt has punctured the oil pan. The fact that they were close enough to the pan to allow the bolts to make contact at some point is what makes me believe the engine was reinstalled too low. Anybody ever hear of this? Obviously the engine will have to be raised a bit, but I'm wondering how much wiggle room there usually is when lining up the transmission to bring up the engine? |

If the boat was properly aligned, it may be that the engine sits very low. Yes it does seem odd that the tracking fin punctured the oil pan, long bolts? See if the alignment was done properly (without moving the engine of course), and if not, you may have a leg to stand on with the shop that reinstalled the engine. |

With all four mounts sitting where they belong, how much space do you have under the pan? It's possible longer screws were used in replacing a tracking fin. It's also possible that the engine didn't go back in gently. This is the first I've heard of pulling an engine for a steering cable... ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

Sorry, I am away from the boat and can't get pictures for the time being. I have begun searching for oil pans for Ford 351 based marine engines. Hoping I can find something! I am wondering how much room there is to move the engine and maintain proper alignment? The weird thing about the whole situation is that, prior to this happening, the boat ran smooth with no vibrations or signs of misalignment. Could I raise the engine and maintain alignment? There must be some play in the prop shaft to be able to do this, right? |

Check out this thread: http://www.correctcraftfan.com/forum/forum_posts.asp?TID=25604&title=85-sn-2001-351w-oil-pan" rel="nofollow - http://www.correctcraftfan.com/forum/forum_posts.asp?TID=25604&title=85-sn-2001-351w-oil-pan Someone found one on Amazon, there was some business about relocating the dipstick, but otherwise it sounded like it worked. Definitely give Billy at mycorrectcraftparts.com a call too, and also try Jody at Florida Inboards. |

No, there is none to very little. The strut is the starting point and then forward through roughly the center of the log. It doesn't take much engine movement to get to the less than .003" needed between the coupling faces. If you don't understand this, please take some time reading up on alignment. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

could take the pan to a shop and have it tigged. No need to replace ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

| Might as well replace, how much is getting a pan tigged cost? Going to have to pull the engine anyway to get the pan off. While its out, shorten the bolts for the fins, no need for more than a couple of threads exposed above the nuts. |

We plan to shave off a thread on the fin bolt. There is roughly 3 full threads exposed above the nut right now. The shaft appears to be slightly lower than centre in the shaft log, which should help our case in trying to get a little more clearance on the bottom. How much room do you guys have from the bottom of your pan to the top of the tracking fin bolts or the closest obstruction? |

J, You should not be worrying about how many threads you can shave off the machine screws for the fins. You, need to do a complete alignment!!! Start from the basics. it sounds like that "back yard tech" just through the engine back in the hull.

Obviously a complete realignment is in the works as the engine is going to have to come back out to do the repair or replacement of the pan. But as you said before, there's not much room to adjust the engine and maintain good alignment. There were no vibrations or obvious signs of misalignment before this issue cropped up, so I'm lead to believe, based on your previous statements, that even when correctly aligned, we're not going to gain much room down there. Thats why a thread or two will likely come off the bolt. I don't want a repeat of this issue! |
