Hi . I'm pretty much a newbie when it comes to owning a boat and diagnosing problems .
I have a 1992 Lowe "pro fisher" 16 ft . 30hp 2 stroke Evinrude . Manual tilt / trim .
If I run the pin in the second hole the boat will get on a plane but will dig the bow into every little wave .
If I move the pin to the third hole the bow feels like it wants to come up but the prop keeps ventilating .
The cavitation plate lines up with the lowest part of the hull pretty much perfectly .
I have two group 27's under the casting deck on the bow as well as a group 27 at the transom for starting the engine .
The only people I can try to get advice from have heavy fiberglass boats with 100+ hp .
I am getting about 22 mph at a maximum rpm of 4500 rpm .
If I get a blow out the tachometer shows 6500+ rpm , so I'm not too sure if I should worry about a faulty tach .
I can not figure out what prop is on the boat now to use as a reference .
I was convinced I needed more engine to get on a plane until I came to this site .
Now I am considering a Davis instruments hydro foil to discourage the ventilation and get the bow up .
I am also wondering if a 4-6 inch Jack Plate might make more sense so I can get the prop further from the transom to take advantage of the rise of water behind the boat .
I can not move the motor down any further its already as low as possible without modifying the transom .
Curious what you guys have done to correct problems like I'm experiencing .
Please share your experiences and solutions .
