Stick with this... I get to the point eventually!!
Last year right at the end of the season I fitted some used Trem launch wheels to my Zodiac 340 Acti-V... not used the boat since then. Just set it up to examine after winter storage and find I've done something stupid... fitted the wheels in apparently the most suitable place but the outboard tiller catches the wheels when raised and prevents a hard right turn.
They are this type as fitted to another ribnetters SIB and are rated to 180kg ...
The normal/cheaper Trem design (and many other makes) doesn't have that extra "button" near the bottom of the transom so are only rated 100kg and it's this button that's giving me trouble in relocating the legs further out on the transom.
Mine is an air floor and fitting the legs at a similar height to that in the image brings the inside end of the button bolt and nut where it will chafe on the back of the air floor which presses very hard against the transom at that level... apart from the immediate position I have it in now where the air floor is held a little off the transom due to an existing bracket. Hence me fitting the legs at this slightly inward position so there was no chance of the floor rubbing through on the nut.
So the only way to fit the legs far enough out so they miss the tiller is to either leave off the button which downrates the legs by 80kg and really don't want to do that.... or to raise them 30-40mm so then the button will fit with its inner nut above and clear from the air floor... but the problem then is the top of the tyre is so close to the underside of the boat floor I'm worried about it rubbing through the fabric (have had this nearly happen before).
Seems the only way to set the legs higher on the transom retaining the button is to fit smaller diameter wheels. Quite happy to do that as we've had legs before with the smaller tyres before and it's never been a problem with rough ground etc.
But I can't find anywhere smaller rubber tyre plastic wheels with a 30mm bore which I need.
Any thoughts appreciated!
