Re: no power

thats pretty much the way it is with out trim tabs or a drive mounted foil to help the boat get on plane when it has a heavy load<br /><br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=24;t=012910 <br /><br />i use a doel-fin but just read the link it covers what your asking my boat will not plane with 6 people in there seats with out it planes fine with it<br /><br />tommays
