Any reasons not to go to electric start and remove the pony?

With the right bell housing you could have both, but sounds like you have good reasons for converting.

Unfortunately it is not as simple to convert the engines that have the side mount vertical cylinder ponies to DE start because the reach of the pinion is so deep from the mounting face. I am no expert, but I think these are usually setup to turn the pony pinion which will still have to be manually latched into the flywheel for starting.

A 12 volt starter is certainly possible and I would not use 24 volt in your case. Just takes big cables for the 12V because of the 2x amperage.

The hot start could certainly mount in place of the pony water connections.

You will want to investigate the fuel system priming capabilities since most pony setups do not have hand primers.

Probably will also want to install a cold start aid ether injector system. The OEM CAT injectors of that era are cumbersome in my opinion. You can use a spray can by hand as well or better than the old CAT cartridges or you can use an electric injector for remote start.

Please take the time to post pictures.......don't get too many boats on here.

maybe this will work, its still available, from my 1940 d13000. thanks 4 looking

Yes Mike, that would work if there is mounting provision.
A current conversion in place of the pony would use the 24v 50MT Delco starter (no less voltage). A non commercially available custom adapter plate is required, type depending on flywheel housing configuration (www.tractorparts.com) or others. Drive end housing and helical drive gear is readily available. Basically the same conversion that would be used to convert the early D8 tractors.

You may want to look into an Espar coolant heater so you can maintain independence from shoreline power and have easier starting without ether.

How about you convert to propane, pipe the air intake for the pony to outside the engine room and install a venture style mixer, the throttle on the original carb will still work as normal. Not sure how the coast guard rules come into play, propane like gasoline vapor is heavier that air, not good in the bottom of the boat.
a 20 pound propane bottle will run a pony for a long time.

is it a given that he does not mounting boss on the right side of the flywheel housing like mine does? i think it was a airstart location, didn't all 13000 flywheel housings have this boss? sorry i dont see alot or know much about the ins and outs.

I agree with cc. We need some pictures of this vessel!
