Given you are in a budget boat, I'd recommend you find a used 4-6HP 2cycle and mount it in the normal location. Get a long shaft if you can find one. This will be enough - you will find pleny of opportunities to spend more money on your boat, if you feel you can afford a bigger, new 4 stroke engine, you should buy yourself some new sails instead.
