Re: Motor Mount and Thrust Plate design - hoping for feedback
Yup. A lot of design elements get constrained by the space you have to fit it in. I ripped out the old engine beds and started from scratch. That made sense for my installation. But my boat is

Re: Motor Mount and Thrust Plate design - hoping for feedback
Dan, that's an excellent drawing!? And I get your point strongly. I'm totally in luck that the center of the propeller shaft, at its angle hits nearly exactly at the top of the bed. Unfortunately,

Re: Motor Mount and Thrust Plate design - hoping for feedback
I was thinking you needed that 90. I might move those spacer blocks between the motor plate and the thrust plate more inboard. As much as possible while still leaving room for the hub/bearing.

Re: Motor Mount and Thrust Plate design - hoping for feedback
Carsten, thank you!? I'm planning on having the plate itself be 1/2" stainless steel - very heavy and sturdy. And all of the supporting items 1/4" stainless steel. What's not shown is that the

Re: Motor Mount and Thrust Plate design - hoping for feedback
You're a genius, Steven.
If you're angling it as a direct shaft drive, just keep the base plate VERY thick. I'm thinking of a half inch plate steel plate here.
Just a simple engineer's mind.
Keep in

Re: Motor Mount and Thrust Plate design - hoping for feedback
Thanks, Dan and Ryan!
Ryan, I'll do that! I hadn't thought of using a threaded bar to prevent the motor from sliding down. I could easily create something to hold the motor up during

Re: Motor Mount and Thrust Plate design - hoping for feedback
Only 3/8 bolts to hold the motor? I think you'll be fine. My ME1616 motor is held with four 5/16 fasteners. It was fine. I tightened mine with a quick clamp pulling the motor pulley to snug

Re: Motor Mount and Thrust Plate design - hoping for feedback
It’s worth looking at the thunderstruck solution - that have a top bolt connecting to the plate vertically with locking nuts and with an eye to fasten to the motor and that is used to tension the

Re: Motor Mount and Thrust Plate design - hoping for feedback
This looks great. Very tidy.
You need to add a way to tension the belt. Make the mounting holes for the motor vertical slots to give maybe 1" (25mm) of overall travel.
I think your mounting of

Re: Elco outboards
I had a 6 hp Tohatsu 4-stroke for years. Great motor.
They now also have a 5-hp propane-fueled 4-stroke. I may go with one of them if I can’t get a suitable electric outboard by spring.
