Hello sailors
Now my boot is out of water for the winter and looking at the motor (in well) it looks some kind of weird! The shaft has an angle of about 15 degrees against vertical (it looks as if the propeller wants to overhaul the motor). Is it normal? Should the shaft not be vertical in the water, and if not... what is the reason?
Have look at this announce and you will see what I mean!

Curious about any explanation
Motor angle in well

Re: Motor angle in well
It could be that the propeller has to go free from rudder movements.
For old 2-stroke engines without a built in motor oil container the transverse heel of the motor is not a problem. However, for 4-stroke engines, this may cause greater oil consumption and maybe also cause not sufficient lubrication. So a model equpped with an oil pressure pump, not relying on splash lubrication will be preferrable. Be sure to ask about this when you buy a new motor.

Re: Motor angle in well
This summer I tested to have my engine in the well.
I have a brand new Mercury 4ML.
My findings are these:
- it works ok with the engine in the well, no problem with water in the well
- it is necessary to tilt the engine so it dosen't chop the rudder.
- I needed to manufacture a kind of "collar" on top of the well to avoid cooling water inside the boat...
- I won a race with engine still in the well
Next year I will most definately remove the external engine mount.
I will also try an electrical engine, easier to stow away when it's not needed. But all the electric engines looks to big to fit...

Re: Motor angle in well
The previous owner of my boot had 3 very good solutions.
He fixed a tube under the control water jet outlet to eject the water at the rear of the boot
He fixed two metal fittings on the 2 smal exhaust outlets in the upper part of the shaft (glued with some kind of metal cement) and fixed a double plastic tube to eject Idle exhaust fume at the rear of the boot.
He used the holes that were previouly holding the external motor support, so he did not have to make any new holes.
He mounted a remote control (gas and gear), so he could control the motor without having to open the back door.
If you are interested I'll send you some photos

Re: Motor angle in well
Hej!
Here are some photos
You can see at the back of the boot (she is now in Berlin) the control jet water running (right) an the exhaust fume (left).
The control jet fitting is a garden hose fitting which has been widen to fit on the outlet (11 mm diameter) and is hold in place with a metal plate and a screw.
The 2 exhaust fittings have been glued with some kind of metal cement like this one (http://www.loctiteproducts.com/p/epxy_m ... ncrete.htm). They join in a single transparent plastic tube connected to the hull outlet.
Exhaust fumes are not very hot, most of it is expelled through the propeller, the upper exhaust is just for idle, when the pressure of exhaust gas is not sufficient to push it through water. Thus a normal plastic hose is OK.
I have head of a german sailor who joined the three tube together so there is only one outlet on the external hull for exhaust gas and cooling water. It might be worst testing.
