Long shaft outboard on a short shaft boat.

[sithethai]

I’ve been using a LS 15hp two stroke
My boat is definitely short shaft it’s only the engine is so reliable I’m persevering,
How much speed do you think I’m losing due to the extra drag.
Thanks

Id say its an exponential thing, the faster you go the more you loose, bit like wind resistance.
