Re: Inboard outboard air cooled engine
I've got the lower unit which I beleive is good, and a 12hp Briggs. Do I sacrafice the 12 footer destined to become a hydroplane?
If so I could be transported back to my childhood days with a few weekends worth of work. The trips I've made listening to the putt,putt,putt. Steering lines in either hand. The wooden rudder swinging to and fro, the bow slicing the waves, the patter of the water on the bottom.
Ok! Here's the plan should I proceed! Build a box to cover the opening in the bottom, fiberglass box to bottom of boat, both inside and out. Make some sort of cowling to go under the boat that would mount around lower unit, not so much to keep water out, the box will take care of that, but to devert the water so as not to make a suction under the boat, ok to gain speed! Mount engine to top of box connecting the engine shaft to the lower unit using the end of a crank that I had sawn off from a bad outboard engine. Make up a sleeve from galvanized pipe that will slide both over the crankshaft on the engine and over the spline that connects to the drive shaft. Use three set screws to secure the top to crankshaft and three to secure the splined end that goes to the drive shaft, or through bolt at the crank and set screw the bottom at the driveshaft.. Or I could have them welded. This way if I need to remove the engine I can unbolt it and and seperate it from the lower unit easily. I'd have the drive shaft cut and welded. Try to rig up some sort of foot shift possibly, don't know if it would work, haven't thought it out that far yet. I plan to have forward, neutral and reverse. I may use rope steering with a wooden rudder, rope steering subject to change.Going to think on it a few days, see if I really want to tackle the project. I like it, I like it alot!
Any ideas for exhaust? I'm thinking big rig stack with a flapper, only in miniture form!
