Question, What is the going rate to rebuild a set of 1100 QV4's ? What is the turn around time ?

merc only 80 grand is what I hear. No idea on time but at that cost one would hope rather quick

80 grand is per engine. Not for a set.

As bad ass as they are, I wouldn't even consider a boat with any QC4V'S in it. I don't know what real-world longevity for them is but according to Merc "refresh time" is required at "200 max hours". $80,000 ea. every 200 hours is some expensive fun!

Definitely the 1% er. Think about it, guys at that level are not pulling and sending them in, so R& R plus I am sure other items need work means add another 40-60K on top of the 160K.

Every 200-300 hours!

Does anyone know the true cost to buy one new?

Diamond Dave

Very good point. Also valve lash is at 75 hours then every 25 thereafter. I wonder what a shop could charge for that?

I had 1100's in my MTI, never one issue. I checked the valve lash myself, easy job, just time consuming. Sold mine approaching 300 hours, still strong.
There are several out there that have gone over 400 hours w no issues. I believe the yellow DCB was one of them.
Ya, rebuilds not cheap...not arguing that.
But, they will go way past 200 hours.

80 grand that’s insanity, gotta be making some bucks to throw away to afford that.

My buddy Todd had some detuned 1100s from Ben at Chief that were half that price and never missed a beat.

salt water motors cost more to rebuild than fresh water motors as they throw more stuff away. leadtime isn't long as they dont rebuild your motors rather they swap long blocks and salt water accessories if yours are corroded
