Re: update 1889 searay 220

are you useing a hydrofoil mounted on the drive or trim tabs on the hull ?<br /><br /><br />i use a foil and at speeds above about 30 MPH it has to much lift and starts to plow the bow<br /><br /><br />i usally run at about 25 to 26 mph and at those speeds its fine plenty of bow lift<br /><br />i have swim plaform on the transome that makes trim tab install bad or the foil would be long gone<br /><br />tommays

Re: update 1889 searay 220

the tabs are going to push it DOWN they should be all the way up at speed <br /><br />at that point the only way to raise the bow is to trim the drive higher<br /><br />at some point you will start to get Prop Cavitation and then your to high<br /><br /><br />what speed and RPM are you geting now<br /><br />tommays
