So I bought a 1967 Swiss 6 15' runabout with an Evinrude 33 hp...It was in great shape. Solid in all the places that normally are suspect. After a bit of cleanning and waxing I got her in the water last weekend. The engine wouln't get me up on plane! 5 mph was the best I could get on the return trip up the Susquehanna River. After some adjustmet to the throttle linkage 30 mph was much better. I have to admitt I was just a bit worried on that first outting...but the second one had me all smiles. This being my first boat (other than a flat bottomed row boat), I am sure to have a great time
