Secured a hoist and stand Saturday. down to the block without a cam shaft and still don't know what the issue is. Should've had it out Sunday but been busy. Short block may be in the cards. I'll know this week.

I just finished engine replacement in my 71 Martinique. It's really easy. Be sure to mark everything and take pictures of your cooling piping. A good rebuild manual is a must. I bought a long block LM318 from marineengine.com. I swapped necessary parts from old to new and bolted it in. Good luck and enjoy.

Paul do yourself a favor and get this book
You will have to pull it,to properly rebuild you might have to bore it and have the crank turned and that cannot be done with it still in.Pull it apart and have a machine shop check it out and make sure they know it's marine and reverse rotation. Then if you need a block go from there. Don't know where your at but I checked the Chicago Craigs List and there were several 351's on there. |

take it out, it really isnt that hard and trust me working on an engine stand is way easier and faster than climbing in and out of the boat.

Engine rebuild questions
Looks like I'll be rebuilding/replacing my 351W. Clacking noise when it cranks then quickly dies. I pulled the valve covers and the oil is mixed with water. Not sure if there is a hole in the block or what. I'll be pulling the intake manifold and the heads tonight after work to see what I can see. I've replaced car engines and done a good bit with old Ford engines but never rebuilt any, but I figured I can tackle this with some help from the Grand Poobahs and such. I know I may be getting ahead of myself but, if it is the block am I going to have a tough time finding a replacement? If the block is in good condition can I rebuild it without removing the engine? I've seen the reverse-rotation rebuild kits on ebay for $525. Is there a better place to buy, a better price anywhere? What else should I rebuild or replace while I’m in there? Getting tired of being towed… |
