Hi

I found this bolt in my bilge when i was winterizing.
I'm worrying about where it could come from.

Is someone able to tell me which bolt it is?

Thanx

trans output shaft to drive shaft coupler bolt?
i'm not familiar w v-drive but my dd may have one or two 2" bolts that secure the bell housing to the engine.

[Ndawg12]

Check all the bolts that secure the starter too, I think they're actually longer than 2" but not positive.

I'm thinking drive shaft coupler also.

[Bake's Marine]

Looks exactly like a shaft coupler bolt to me!

Yep, it holds that shaft coupler bolt tight.

From the above posts, I'm going to guess your drive shaft coupler bolt came out.

For some reason when I bought my boat, I found about 40 large washers in the bilge, mostly stacked together. They don't look like they belong anywhere on the boat either.

No it didn't.....................

Just for kicks you should replace that nut.....and maybe the others while your at it.

I'd replace all the nuts and bolts and lock-tite them all. Of course, don't lock-tite a stainless nut to a stainless bolt.

Pete, does that weld them together or something if you do use lock-tite?

Pete, why loc-tite? what are you supposed to do when you need to check alignment or replace strut bushing?

blue loctite just gums up the threads a bit and doesn't make bolts unbreakable. Just tends to keep 'em from coming loose. Red loctite on the other hand can cause some consternation.

I think there are 3 colors indicating different hold strengths but I think the question to Pete is; why is stainless any different?

IIRC, this was hit on in an earlier thread and as I recall it was due to SS fastener on SS fastener violence. SS, it was stated "has a tendency to gall the metal when it comes in contact with another SS fastener when you don't use anti-seize of some sort. I haven't experience this yet, but I don't work with SS a lot either. I do know that after using "red" Loctite I have broken a number of low grade steel bolts/bolt heads trying to get the bolt out afterwards. I can only imagine the amount of grief, cussing and blood I would spill if I ever user "red" on a SS shaft coupling bolt when it came time to take it off. Not to mention it takes an 80 lb Russian contortionist with hands the size of a Barbie doll to get to the shaft coupling bolts.

[Pistol Pete]

Sorry guys,
I meant I wouldn't bolt a SS bolt to a SS nut.
I would loc-tite a SS bolt to a nylok brass nut.

[Nbk]

Thank you all for the advice

[Sliderfiii]

Blue Loctite would be the one to use.....I found out about SS bolts to nuts fusing if you don't use anti seize the hard way!

[tvano]

to the op; did you find where the the bolt belongs?
