OBO 1975 Invader Trihull w/70hp Johnson Seahorse in Oklahoma City, OK

1975 Invader Trihull 14' w/70hp Johnson Seahorse outboard. Just had on the Grand Lake July 4th weekend and it doesn't like to run very well at idle speed & is hard to start (runs great just above idle & up!). I don't know anything about outboard motors, especially older ones! I've always had newer inboard/outboards, so someone that knows about these motors may be able to work on it to get it running great at idle & starting. It comes with a new marine battery, new gas tank & connections, 2 props, anchor & anchor light and 2 new tires & new marine lights on Dilly trailer! Also, tagged until June 2014. Asking $1200 OBO. Please call or text [removed phone].
