Anyone got advice on these motors.
Does the command thrust work ok?
Does it affect top speed and hole shot?
I imagine that bigger props will help at slow speeds in the ruff stuff.
Would be as a twin set up to replace etec 90's

They always used to be aimed at pushing heavy loads, like barges, punts, etc. Lower geared to swing a larger diameter ( not larger pitch) , get a better bite for thrust against resistance, not speed. .
I've got a 115hp CT on a 5m cuddy cab
No issues with holeshot or top speed, It leaps out of the water and a max speed of 70kmh so I have no complaints at all
It also planes at a lower speed than the 90hp V4 Johnno it replaced, These are such a torquey motor right through the rev range and cheap to run
Ran a counter rotating set of 90 CTs on a 5.2KC, great holeshot and top end speed. Great fuel economy, highly recommend them.

thanks mate. Was there a temptation to go the 115’s as they are the same weight?Quote:
