don't worry i couldn't spell earlier .

Does seem to me that Honda have the inflatable v floor sorted . It too flexes and gets uncomfortable in a chop , but I guess all sibs do . However you just blow it up and go no friggin about with toggles and keel trips etc its just one piece .

i think that that is the problem

the earlier <2002 and zodiac310 and below have a seperate inflatable keel that is inflated through a hole in the air deck, whilst the later and 340 models the keel is connected via a pipe to the underneath on the main floor and takes its pressure from the main air deck

so its not possible to inflate the air deck fist then the floor as both go up at the same time

i did get mine straight once or twice by inflating air deck with boat on its side and sticking my knee in to it ! whilst misses blew it up (huumm)

not best choice of words

Ok, just checked the dimesions of the propeller and it's a 9-11. Presume this means it's a 9" prop with a 11" pitch.

I've got a 17 years older(1988) version of the same engine which I've been using on a 3m Avon for years without any ventilation problems at all. This one has 9 1/2-10 stamped on it which I assume means it's slightly bigger in diameter but with a shorter pitch?

Could this mean that the newer engine I'm getting problems with is geared slightly too low and hence slipping when accelerating or would the different proportions in diameter and pitch cancel one another out (ie smaller prop with longer pitch is the same as larger prop with shorter pitch) ?

The prop from the old one fits ok so will give it a go next time I'm on the water but I just wondered what people's thoughts were on this...

I know there's loads of posts regarding pitch etc but couldn't find anything specific to my problem.

Thanks for any comments

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).

rgds,
Heretic.

10hp is the max recommended but the max allowed is 15hp. I find mine runs very well with a 15hp the boat can cope with it. I did a speed run along side another boat this weekend and got 26knts gps with very low fuel 1 person and minimal kit onboard That was early one morning with flat water it was running perfectly you can feel the wind lifting the boat up of the water. I find if you have a few people in the boat the extra hp helps. I also did a bit of kneeboarding off my boat for the first time i thought it towed very well. Two people in the boat driver and spotter and relativly light person on the board.
