Hi all

This NZ winter we have replaced our tired 1988 V6 motors in the 268DA with some late 90"s vortec 2bbl Tks motors offering 190 hp at the prop. So total hp is probably similar to the original 205hp engines which were measured at the flywheel. Engines are a lot smoother and now have top mounted oil filters and single multi rib belts to eliminate the belt squeal on the earlier motors. Should make the engine servicing downstream a bit easier.

So the next stage in the upgrade is looking to replace the current 17p vengeance props with some 19p.

I can move to 14" 19p vengeance 48-16316 or I do see the larger 15.5" 19P Mirage Plus 48-13700

The goal here is midrange performance/economy, normally cruise around 3000rpm.

Any thoughts on Vengeance verses Mirage plus? What stainless props are others running on their 268DA twins?

Thanks

Darrell
 
I'd stick with the Vengeance - if, in fact, you do want to go SS that is, since Al is more than adequate for those engines. The Mirage Plus is better suited for higher HP engines with more torque. I don't think the V6's you have are properly suited for the Mirage.
 
I'd stick with the 17's. I'm running 19's on mine, and when we have her loaded with gear, fuel, water, and people, she struggles out of the hole.
