Can you help me "please"

[Guest]

Can anyone out there please help. Quite a simple Question, which is best with the piece of wood or without the piece of wood. In other words will it help the boat or will it not. At the moment its not glued in but years ago I saw a model with one and thought that sounds like a grand idea. Is it? can you help? Many thankings for taking time out to look and even help. Steve

What sort of hull is it?

If it is a speed type hull, it will tend to keep you in a straight line, and you might have difficulty turning. In this situation a simple P bracket will do, just to support the exposed propshaft.

If it is on a scale type slow runner, no problems.

What does concern me is the steep propshaft angle, this will use a lot of power trying to push the bow of the boat down, rather than pushing the boat forward, and if it is a fast boat will need a lot more power to get it to plane.

Hi John, its a home made some errrr 20 odd years ago, no plans at all, for an out and out speed boat. If i was to put the prop back on it only just with a max of UMMMM 2mm clears the underside of the boat. The shaft is in the keel of the boat rock solid it dont move. Its another one of my boats that my daughter found and wants me to get working :-) (see jet arrow thread). So if i read you right, your saying leave it off to keep up the speed? because of cornering.

I would suggest that you experiemt with it fitted and without it fitted and see what you think.

There will almost certainly be plusses and minusses with both arrangements and it will be a case of which you think outweighs the others for your own purposes.
