Ok, hi all just registered
Im a total newbie to all this, but having use my own Cadet fastroller acti-v 340 a couple of times now, I have noticed something similar.
I drive it on an old (20rys) Evinrude 10hp 2-stroke, and occasionally itll "spin up". I thought this to be the prop leaving the water through ?
Ive used it only on Loch Lomond, which can get a bit wavey in the perpetual wind you get there, and I had assumed it was this which was causing apparent "slipping" of the engine.
Last weekend I was out, and the water was dead calm, I was able to whip about carving tight turns, without any hint of this phenomena.
On another note, I can always let rip with the throttle from a standing start and whilst the bow rises up like an angry elephant, theres no slippage. My point is Ive only noticed it when Im haring along and there is a swell (say, 2feet) in the water.
Dont suppose this actually helps
, but it is possibly another line of thought to consider. ie see how it runs on a nice calm day before doing any drastic mods
On a completely different note, how do you find a 15hp runs on your boat ? I thought 10hp was the max allowed - Im thinking of a new engine
Ill maybe open a new thread for that question.
Next time Im out, Ill be sure to experiment and see when and where I can reproduce the effect.
Thankfully my own keel runs pretty straight down the line (first thing I checked when I got it).
