So after my last outing I noticed one of my engines was making a weird rattling noise. Checked clean out plugs, couldn’t find anything. Decided to check around today as I plan on going out tomorrow and both bolts on the front left motor mount are out, engine is off from the holes by about quarter inch. I found the bolts in the bilge. It’s under warranty but I’m sure it’s going to be a week or two to get it in the shop. How hard you think it would be to get things aligned and get the bolts back in. Should I even attempt to run it without the bolts in. The other three mounts and bolts look secure. Everything looks good on the other engines mounts. Pretty frustrating on a brand new boat.

That sucks...Don’t take offense to this, but if you are asking how difficult this would be, it’s probably too difficult for you and you’ll end up cross threading the bolts..

That being said, I think the average mechanic could easily repair in minutes...
 
Looks like you could get them back in fairly quickly. But wouldn't run without them. I would also check all the other motrmount bolts make sure they are all tight
 
I think if it was mine I’d throw some locktite (blue) on the bolts, use a pry bar to push the engine in place and CAREFULLY reinstall the bolts. As in, start them by hand with no tools to ensure they aren’t cross threaded. Not a technical repair by any means.
 
Oh wrap the pry bar so you don’t scratch up the gelcoat in there.

Must have not put thread locker on those bolts...I'll be checking mine and all of the clamps, hoses, etc. this weekend. Hopefully you can get it fixed up without much hassle.
 
There is red thread lock on them. Any reason the dealer would remove these for a 10 hour service? That was done fright before my last outing. Would like to know before I call them tomorrow with my angry voice. Recommended places to push? Exhaust manifold looks to be the best option looking now, I don’t want to do any damage though.
 
I‘d stick the bar right down between the hull and the engine mount bolts and push it over there.
 
Unfortunately very consistent with what I found with my boat. Many bolts and screws were loose when I got mine. I took a Saturday morning and went through the whole boat and tightened up everything I could find and think of.

But, back to your issue, @Dixie Highway hit it right on the nose. Don't run without them, but easy fix. Just be careful to start by hand so you don't crossthread.

Man, you can't map it out for someone better than that. Nicely done, @Dixie Highway .
 
Alright now I know what I will be checking in the morning tomorrow.....
 
I took a screwdriver, some antiseize, and a ratchet set. Went through the whole boat... Doors, hatches, tower, etc. Anything I could find. Cheap insurance for some peace of mind. I did say antiseize--while I was there I pulled each connector and threw some on. Protects against corrosion and seizing all in one.

Yep that will be happening tomorrow.

None taken. I’ve got some basic mechanical skills, oil changes, brake rotors/calipers, trailer wheel bearings etc, never dealt with pulling motors or motor mounts. My biggest concern was the weight, I got some tow straps and such but no great way to move that much weight. First thing I did was push around on the top of the motor and she wouldn’t budge. Turns it it didn’t matter. Called a buddy for a second set of hands before I even posted here, with a little muscle and pushing on the bracket from the very bottom and the other guy putting the bolts in it was pretty easy.

Can’t forget the beer and some swear words! Wouldn’t be a project without that ??
 
I would check the coupling clearance to determine if it is shimmed properly.
