Volvo Penta lower unit 3855907
Looking for one of these for a decent price. Limited availability out there and they cost an arm and a leg. Does anyone have one laying around? DP-SM 1.78 gear ratio.

Hey hb welcome to the Cobaltchat forum. So glad you found us!
Haven’t seen one of these listed out there. Maybe BigBlockPower will source one for you. Do you own a Cobalt? Any pics?
Again welcome aboard mate!

Thanks! As a newbie, not sure how to post pics. Also, how do you put your details (boat, location, etc.) at the bottom of your post?

Gotta love that $10k stainless arch option and of course the extra extended swim platform!

Yep, but the Arch keeps me from going under a bridge to 2 of my favorite lakes on the Chain!

Ooh. Sorry to hear that hb. Those two items are built like a tank and are my favorite features on our 263. Well maybe the 425 horse Merc with captains call are first...then the arch and platform.

Re: Volvo Penta lower unit 3855907
Thanks! Ha, no, earlier this year we beat up the prop on something in the water, fixed that, but this time whatever happened there’s a big whole in the housing so unfortunately I can’t do a core return.

Beautiful 272.!
Does your insurance not cover submerged impact?
I damaged a pair of Bravos years ago and Allstate Covered it.
2 new lowers. You may want to ask as this is a big ticket going forward.

Re: Volvo Penta lower unit 3855907
Survey was ordered by insurance company and the surveyor said it was internal, blew out of the housing from normal wear and tear. Our mechanic (who we have had done work before and is highly respected in our area) said in all his years he has never seen this.
