I found a crack in my lower unit housing. It runs from the edge near the prop forward towards the actual lower unit itself. No oil is missing from the lower unit.
I used the boat a couple of weeks ago at the coast and the damage must have happened on the last day we fished because the clean up was done in the dark and I think I would have seen this during the washdown.

Can the housing be repaired or am I going to need a whole new lower unit?

One opinion from a mechanic said it looked like strike damage due to no flex in the stainless prop....He said it didn't look like freeze damage and I'm not sure we've had a freeze since it was last in the water and flushed.

pics are needed

if you hit something at the coast, call your insurance company

On Merc it's generally freeze damage from water sitting behind the prop with the motor tilted up . On suzuki I've seen it a number of times with no visable impact damage. It can be welded.

Suzuki 150...What do you think might be the cause if it's a non strike problem?

Just found this today about 2. Just trying to get some info so I know what I'm dealing with. Thanks for the replies.

hmmmm!!!! question?? if you fill a beer mug half way with water and put it in the freezer will the glass break? I think I have money on the correct answer.
