I found a couple of pictures of Irwin 28 with the outboard motors.
This admittedly does not make the sailboat any prettier, but it helps with:
- no oil in the bilge,
- no fumes inside,
- no noise inside,
- lots of extra room for additional batteries, sails even future electric motor

Seems like 9.9 hp should be plenty with these features:
- 4 stroke
- 2 cylinder
- 12-volt charging
- 4 stroke
- 2 cylinder
- 12-volt charging
- high thrust prop
- deep (long) prop
- deep (long) prop

Do you have experience with outboards on the Great Lakes?
I would really appreciate constructive comments...
UPDATE (August 13, 2008):
1) I have delivered the boat with a loaned 9.9HP 2 cycle up Chicago River, Chicago Harbor, to Belmont Harbor.
2) We sailed and motored in hefty winds with the same 9.9 HP, which was sufficient.
3) I hate to lean over the transom in heavy seas and cord-start the motor. I rather have the battery starter in the cockpit.

BTW, I have been using the 55 pound of trust electric motor on my Day Sailer and it works very well on protected lake, but not in the strong wind. Don't use it on full speed, or you drain the deep cycle battery too fast. You can slowly cruise around for a good hour.
