I also have a Mitsubishi TLE43. If you go 2 stroke I would say it is a wise choice.
Very dependable 2.2hp motor. Staton sells this motor for 299.00 but you can get the motor from Visa motors for 188.00. I did. http://www.vizamotors.com/
He is out as of last week but should have more by now. You just need to give him a call. Very good people and fast service.
