Why are them engine hatches on some 28's raised and some flat with foam and vynil? I can see why some of them are raised for a blower application but some I see are raised on a N/A engine.

higher x dimension and exaust clearence

A single 28 should be able to have any NA engine under a flat hatch. My 525sc fit under mine with a 2" raised area for the flame arrestor and I had a notched transom which raises the X dim 3" over standard. Von Bongo's 28 had a 575sci under a flat hatch.
The engines sit much higher for twins and a raised hatch will be needed in many cases.

Plus they look sweet, if you can do without the pad.

for 3k you need to get all over those 174's in the swap shop to fill your hatches!!!

Then I could not afford a new interior but it is a thought.

Welcome to my world. Thats why they make colored duct tape

Towels work great also , if u cannt find the right color duct tape.

But you would have to have something to tape, my back seat is gone LOL

Anyone have pics of a raised hatch with a sunpad on it? Thinking of getting a thin pad on my raised hatch but afraid it may look out of place.
