My twin Mariners 60s are currently running 13.75x17 Solas ally props, running with just myself on board it tops out at 5200rpm but I feel it lacks some sharpness on the throttle. Cruising this weekend it sat happy at exactly 4000rpm doing 23knts, I would just like that little more "poke". I also felt that manoeuvring at idle speeds was a little numb.
I'm toying with the idea of going to 15" props, these bigfoot engines actually come with a 15" prop as standard, would it have 17" props on it because its a twin setup? Do the same prop rules apply with twins as they do for singles?
There is a place on this planet for all of Gods creatures.........right next to my tatties and gravy.
