    I know they have the 6.5 cheaper!, but I know that its to heavy for what I'm looking for. Just would like to be at idle without the prop spinning.

    use a go kart clutch ..strong and will easy handle the power and you only need a sleeve on the shaft to bring it up to 19 mm

    Kiwi - it is the 52cc scooter engine and the Honda clutch assembly that adapts to a 5mm square end.

    wallyeye,

    It is a 5mm square end. At least that is what the machine shop told me that machined the shaft for me.

    Now, it's just off to the water patrol to get it inspected and taking the bill of sale and water patrol inspection/approval, together with proof that you paid last years property taxes and then get a title as an outboard and getting that little sticker that says "I paid my taxes" and stick it on there!

    I went duck hunting this morning with my new 59cc long shaft mini motor that I made from using this form. It went through the weeds great and it ran pretty well. However,



    The honda clutch kit kept getting really hot and smelling funny! After I got back I took it apart, and found nothing wrong with it. Has anyone else had any problems similar to this? From looking in that housing I see the bearings, but I do not see any way to lubricate them. Should I pour some oil down there, and let it soak through. Do you think this will help?

    this is a sign you have too much pitch on the prop so the clutch is overloaded..reducing the pitch will increase the revs and keep the clutch better engaged ..like all outboard you need a rev counter like a tiny tach to check the rpm at wot ....

    Could that be done by lowering the motor down, which would also reduce the angle of the long tail/shaft?

    the pitch on the prop is the twist on the blades .you have too much twist ..dependent on what its made of you might be able to bend it a bit

    The prop is made out of die cast alum. It is a Young's Prop. I do not think that it can be bent. I could always lock out the clutch and solve the problem correct?

    Well the props are always the problem with these motors ..I dont think the youngs prop lets it rev high enough really a prop with less pitch is what you want but locking out the clutch is one sollution ...people tell me that if they start the motor and drop the prop in the water it stalls ...you will see some information above on using model boat props which are intended for these motors as many model boats use the weed wacker engines .....I have two on order ....

    Are you building something similar? I would like to try something else, if possible.

    I am using the 59cc motor and I am not having any kind of trouble with stalling, even if I start it out of water, rev it up, and then drop it in the water.

    Do you think that these boat props will push a big boat?
