Casey,
Welcome to CCfan. Pictures of your project will certainly help. Is the engine the original to the boat? So you understand the principals of a direct drive inboard, I suggest you start with taking a look at this video. |

The 307 OMC was an option in '72, so there are Mustangs out there with small block Chevies for sure. You'll need to prop the boat appropriately with the extra cubes. Hopefully you're installing a reverse rotation engine to keep the boat from leaning to stbd excessively.
Welcome! |

Reverse rotation- nice!
350 was never an option in the 16' mustang. The larger displacement (cubic inches) will require a prop with more pitch in order to get optimal performance from it. The most common engine/prop combo for that boat would have been a ~220hp 302 and a 12x14 federal prop. An old school hand finished (federal or oj) 12x15 would be a good place to start. If buying new, splurging on an equivalent sized Acme (1214, 12.5x13) would also be a strong consideration. |

Casey,
Does the engine have adjustable mounts? If so, the install should be pretty easy. If not, then wedges are used between the mounts and stringers. Still not too bad of an install just not as convenient. Keep alignment in mind. I suggest you do/check the strut to log alignment first before you drop the engine in. Speaking of stringers, what's their condition? have you checked them? Now's the time to check without the engine in place. |

Yes, lags. What I didn't mention is material. In the good old days, The lags were silicon bronze which has a fantastic corrosion resistance but they don't make them anymore. The next best is stainless but, make sure they are type 316. The 18-8 stainless from China you find at the home improvement or hardware will rust. Mcmaster has the 316 in 1 piece quantities. |

Gotta say Pete, I've never witnessed Silicon Bronze ever being used as engine lags.
I believe most were all grade 5. Fastenal has S/B lags, But they are very expensive and they only have 3/8" and 1/4". |

Come on Al! I thought you went as far back with boats that I do!!! BTW, I never have checked with Fastenal since I strongly disapprove of the company. Are the S/B lags square or hex heads? |

Casey,
One may be corroded more than the other but, once installed, mounts should be tight both up and down as well as side to side. How about those pictures? |

I should have figured, but you never know. I'm thinking that i just need to tighten them up as they are the adjustable kind.

Casey, Submitting to the diary section is great. Keith reviews each submission and then will enter yours. We sure don't want any Matercrafts showing up there! For posting pictures in the forums, use "post reply" and not the "quick reply" Click on the icon of the tree with the up arrow. Boxes will come up to prompt you for loading from your computer. Some also like myself use a photo hosting site like photobucket. Give it a try. |
