water coming over transom at speed

[Das Boot]

Hi All;<br /><br />Bought a Zodiac GT about 15.5 feet long, it has a Mariner magnum 40 HP short shaft...........<br />anyway at WOT (about 5000 rpm) and around 30 mph...... Water is being pulled in over the transom where the motor clamps on.....I wonder why? and what i can do to stop it?<br /><br />Thanks;

Motor is sitting too low. You'll need to mount it a bit higher.

Thank You Gents......... you are correct, during a run last night with my wife at the wheel i observed how the water was being splashed in.<br /><br />First i'll try to move the engine up by raising it 1 set of bolt holes, if that dosn't work i'm in for major surgery

Not really. A jackplate would get you higher if need be. There are some fixed plates that are not too expensive that will work.<br /><br />Such as These

Thanks for the info Admiral;<br /><br />I'll look into the jacking plates if necessary.
