Twin screws
Posted: Sat Jul 15, 2017 9:45 pm
Anybody else got twin motors? I'm equipped with twin Mercury 25hp (not counter-rotating, but at this hp I doubt it matters). Only the port motor is linked with the tiller, but there are still several advantages:
1. Department of Redundancy Department
2. Maneuverability in tight quarters or if rudder fails
3. Small enough to manual start easily
4. Light enough to pull out by hand and maintain
The PO stacked the second throttle on the original, and they stick out a bit into the cockpit, but it's not a problem. I'm sure I'm carrying a little more weight aft which may affect my weight distribution, especially for trailering (see my recent post about trailer woes), but Mercury lists these motors at 174lbs each, and I doubt a single 50hp weighs much less. One concern I do have is that my motoring speed doesn't seem very fast, maybe 7-8 knots at 3/4 throttle, and PCI lists a 9 knot speed with a single 20hp.
Anybody else have experience with twin screws on a Telstar?
