Stavanger, Tuesday
I guess I would choose engine size depending of how well the boat sails to windward and how my home harbours is. If my only concern was to get home when the wind died, then 3-4 hp would have been enough to push my 3 ton Johanna. However, although, my harbour is well protected from swell or currents, the place can be quite windy. For this reason backing out of the berth and getting the boat moving (and turning) quickly enough calls for quite some power. The vectored thrust of a powerful outboard is particularly welcome when a stiff breeze pushes on that thick mast. There isn’t that much room for error here and even a 6hp engine would be on the small side.
Now I just had a look on the web. Yamaha still makes a range of engines with high-thrust legs (FT series). They not only have special propellers, but the gear ratio is around 3:1 against the normal 2:1. I notice that they are e bit lighter than the model I have since they now use around 200ccm engines. The 45kg 8hp model FT8DMX (manual start, extra long leg) could be an alternative on Redwing, or what do you think? It also comes in versions with electric start and even with remote control. I guess other makers also have similar models.
After a few years with an adjustable bracket, I found a position which the engine worked well in, both for sailing and motoring, so replaced the adjustable bracket with a fixed one to bring the engine closer to the boat. If you install a bracket that moves up and down on rails, sort of, the trick is simply to install a 2- or 3-part tackle (What is it called?) to raise and lower the engine. I had that on Malena.
