A 46 with QSM's is a nice ride.

If that is what you want to do you better find an expert. I know a yard in NJ that specializes in Bertram repowers. It is not as easy as droping a new set of motors on the engine beds. The shaft location comming through the hull has to be changed.

That sounds closer to the cost for one engine in the C-18 range. Or was that just the cost of the engines without any of the other costs?

8V-71TI boats had 2" shafts and 28 X 32 or 33 , 3 blades , 8V-92 TI boats had 2 1/4 shafts and 28 X 29 3 blades I believe. 2-1 reduction on 8-71 1.5-1 on 8-92

SeaBoy... Love those 46 Bertrams! Good luck on the repower but remember you won't ever get a return on the cost. We did the same with a 43 Post and fitted her with new 3196 electronic CATS. All was good until we decided to sell her. At that point it was just another used 43 Post and sold for the same price as those which hadn't been repowered.

Not trying to give you grief but do your homework before you spend those hard earned dollars on a repower. My suggestion is to just find another boat which is ready to go.

Lets confuse this a bit more. Can you still buy the pervious generation 660 hp QSM11 "Recons" from Cummins? That would certainly be attractive for a 46. Those QSM 11 weigh a LOT more that the perviously mentioned 1500 lbs. More like 2400, but if the 8V-71's weigh 3000, that is still a weight savings of 1200 pounds. So you get old model 15 liter V-8 MAN power levels, which supposedly worked great in the Viking hulls in that size range, and probably better economy with 6-71 weight.

I repowerd a 43 Hatteras with 635 HP QSM 11. Went from a 19 to a 28 knot cruise when seas let you. One nice thing is you can pull back to 21 to 22 knots and still burn less fuel than the old 6-92's.

I've always liked this Hatteras repower video. It will give you an idea of the transformation.

Yeah thanks very much. I have the owner right where I want her. Dealing with a lady who is going through a divorce so she is letting the boat go for next to nothing. I wouldn't mind re-powering if I have to, I will still be up and running for less than 80K.
I am due to have an engine survey this weekend, so I will have a better idea where I stand mechanically.

No, the "timbers" are called stringers. Each of the four stringers to which the engines mount ought to be capped in metal, either steel or aluminum, attached with both adhesive and bolted transversly through the stringers to spread the load and to spread the engine's thust as well. The metal capping the stringer is the engine bed.

OP, a whoole lot of labor is involved in swapping engines, if you are going to pay for the labor, which is the major expense in my experience, you ought to go with a more modern engine, like the QSM.

When it comes time for the exhaust, call Dave Cook at DeAngelo Marine Exhaust, he'll do you right.
