Hello, I have been researching gearing in vdrive transmissions and they range but alot of them are 1:1 in thier final gear. a powerglide transmission for an automobile is also that. My idea so far(im sure it has been done before) is to add a custom thrust bearing on the end of the transmission cone, run a shaft with a prop right off of the yolk. I was wondering if anyone knows where to look for ideas.for the surface drive im thinking fixed. not like an arneson. using trim tabs for trim and a rudder for steering. also, this is just an idea so please dont hate haha. any information on the topic would be appreciated.

THANKS

Just a idea check these out lancing marine surface drive may give you some help.

I will def look into that. Thank you!!

Mike08K,

do you have a rudder system design in mind?

Would the rudder be retractable to allow for low water depth operation?

These drive shaft angles would have to be altered...but its an idea

im thinking something like this. this is off of an old 70's surface drive. input off this design would be appreciated as well. thanks for the response

Are you a fabricator ? Also what hull are you thinking of mounting this to?

You're going to need a fabricator, a machinist, an engineer, and all their tools/time. That couldn't possibly cost less than 15k.

How much of those assets do you already have?

Love that old 70s photo
They just needed to extend the drive a foot or so to get to clean water and it may have caught on.

Well I am a fabricator. I have a access to a CNC with my machinest cousin. As far as a engineer that why I need you guys hahaha

Also pismo10 ...that is def a cool one haha def the pic that inspired my idea

Also a 22-24,deep v hull..

Thanks for the responses guys!!

go for it the worst thing that happens you spend some time and money and it doesn't work out, but maybe it will!
