    Hi everybody,,

    Sylvain, from France again for another classical question for which I found no answer…

    I found two kinds of outboard brackets :

    The first one is very simple, and can’t move. But it’s easy to build : http://www.accastillage-diffusion.com/publicmedia/formatted/537/41/fr/T50015.jpg;maxh=229,maxw=305.jpg

    The second one is articulated… but is it necessary? :http://www.discount-marine.com/sites/default/files/images/produit/5156/support_moteur_reglable.png

    If I tilt the engine when I do not use it, the fixed version is not enough?

    Many thanx

    Sylvain

    Salut Sylvain.

    Many of us use this kind of bracket https://seamarknunn.com/acatalog/removable-alloy-outboard-bracket-3622.html?gclid=EAIaIQobChMImtjV_crQ2AIVSrXtCh04igL-EAQYESABEgJEkPD_BwE

    The plate is fixed to the transom by through-bolting (use a backing plate inside the buoyancy tank) and you fit the rest of the bracket only on days when you need the engine.

    With the engine tilted nearly horizontal the hélice is just lifted out of the water.  If you have the articulated bracket, it would lift the moteur further out of the water but I would worry about the mainsheet catching on the engine.  I moved the mainsheet attachment point on the boom a bit further forward than usual to help with this problem.

    Bon chance!

    fixed; with a flat socket on transom that the bracket slots into works well for me. sourced from Ralph Roberts who also suggested where exactly i should fix it on my wooden boat. big question is; do you have it to port or starboard?

    Hi Mike,

     

    Many thanks for your anwer,

    I just see it, I did not receive the email notification about it!

    I had seen this kind of bracket but I didn’t know there were two parts 😀

    So I understand much more how it works and so the advantages of it..

    I’ll see if I can buy one…

    About the buyoancy tank, I suppose I’ll have to open it if I want to insert a backing plate inside it… and to close it whith fiber glass and polyester to make it dry again?

     

    Many thanks!

    Hi Nicko,

     

    I think I’ll put it on babord…

    But one more auestion to every body : when going with engine, you turn right and left with the rudder (keeping the engine on a fixed position) or with the engine (turning it)???

    i found that when in a big area of water steering by the rudder was most convenient but when manoeuvring in tight places using the outboard gave more control

    It makes sense…

    The turning radius may be smaller with the engine and larger with the rudder, I suppose…

    Also there has to be a good flow of water over the rudder before it will work effectively. The engine’s propeller works at very low boat speed, and can be pointed in any direction.

    Ha yes it is true that without speed the rudder will not allow to maneuver at low speed, while turning the engine, yes … Thank you for putting this point forward, I had not thought!

    Sylvain, you ask about placing the backing plate, cutting an opening and re-glassing.  No, that should not be necessary.

    Do you have a hatch on your rear deck? On my Mk 2 I was able to fit the backing plate inside the rear buoyancy tank by reaching through the hatch opening.  The transom is thin, flat glassfibre and cannot support the load of the outboard and bracket so if you fit a piece of plywood or Paxolin, cut to shape and bedded onto mastic makes a good way to spread the load.  After bedding the backing plate, drill through for the bolts and get some help fitting the bracket, because you cannot hold a spanner on the nuts at the same time as you turn the bolts.

    Bonne chance.

    Mike,

     

    Thanks for your post…

    My Wayfarer is a Mk1 GRP, so the transom is made of wood, around 20 or 25mm (I d’ont remember…), and looks very strong.

    But there are no hatch in it…

    So, it looks like I’ll have to open the buyoancy volume… :-p
